- !important attribute
- For basic functionality of the !important attribute with overloading
- of several styles of an element, changes in inherit(), merge() and _parse_properties()
- are sufficient [helpers var $_important_props, __construct(), important_set(), important_get()]
-
- Only for combined attributes extra treatment needed. See below.
-
- div { border: 1px red; }
- div { border: solid; } // Not combined! Only one occurrence of same style per context
- //
- div { border: 1px red; }
- div a { border: solid; } // Adding to border style ok by inheritance
- //
- div { border-style: solid; } // Adding to border style ok because of different styles
- div { border: 1px red; }
- //
- div { border-style: solid; !important} // border: overrides, even though not !important
- div { border: 1px dashed red; }
- //
- div { border: 1px red; !important }
- div a { border-style: solid; } // Need to override because not set
-
- Special treatment:
- At individual property like border-top-width need to check whether overriding value is also !important.
- Also store the !important condition for later overrides.
- Since not known who is initiating the override, need to get passed !important as parameter.
- !important Parameter taken as in the original style in the css file.
- When property border !important given, do not mark subsets like border_style as important. Only
- individual properties.
-
- Note:
- Setting individual property directly from css with e.g. set_border_top_style() is not needed, because
- missing set functions handled by a generic handler __set(), including the !important.
- Setting individual property of as sub-property is handled below.
-
- Implementation see at _set_style_side_type()
- Callers _set_style_sides_type(), _set_style_type, _set_style_type_important()
-
- Related functionality for background, padding, margin, font, list_style

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.

+
+**Dompdf is an HTML to PDF converter**
+
+At its heart, dompdf is (mostly) a [CSS 2.1](http://www.w3.org/TR/CSS2/) compliant
+HTML layout and rendering engine written in PHP. It is a style-driven renderer:
+it will download and read external stylesheets, inline style tags, and the style
+attributes of individual HTML elements. It also supports most presentational
+HTML attributes.
+
+*This document applies to the latest stable code which may not reflect the current
+release. For released code please
+[navigate to the appropriate tag](https://github.com/dompdf/dompdf/tags).*
+
+----
+
+**Check out the [demo](http://eclecticgeek.com/dompdf/debug.php) and ask any
+question on [StackOverflow](https://stackoverflow.com/questions/tagged/dompdf) or
+in [Discussions](https://github.com/dompdf/dompdf/discussions).**
+
+Follow us on [](http://www.twitter.com/dompdf).
+
+---
+
+
+
+## Features
+
+ * Handles most CSS 2.1 and a few CSS3 properties, including @import, @media &
+ @page rules
+ * Supports most presentational HTML 4.0 attributes
+ * Supports external stylesheets, either local or through http/ftp (via
+ fopen-wrappers)
+ * Supports complex tables, including row & column spans, separate & collapsed
+ border models, individual cell styling
+ * Image support (gif, png (8, 24 and 32 bit with alpha channel), bmp & jpeg)
+ * No dependencies on external PDF libraries, thanks to the R&OS PDF class
+ * Inline PHP support
+ * Basic SVG support (see "Limitations" below)
+
+## Requirements
+
+ * PHP version 7.1 or higher
+ * DOM extension
+ * MBString extension
+ * php-font-lib
+ * php-svg-lib
+
+Note that some required dependencies may have further dependencies
+(notably php-svg-lib requires sabberworm/php-css-parser).
+
+### Recommendations
+
+ * OPcache (OPcache, XCache, APC, etc.): improves performance
+ * GD (for image processing)
+ * IMagick or GMagick extension: improves image processing performance
+
+Visit the wiki for more information:
+https://github.com/dompdf/dompdf/wiki/Requirements
+
+## About Fonts & Character Encoding
+
+PDF documents internally support the following fonts: Helvetica, Times-Roman,
+Courier, Zapf-Dingbats, & Symbol. These fonts only support Windows ANSI
+encoding. In order for a PDF to display characters that are not available in
+Windows ANSI, you must supply an external font. Dompdf will embed any referenced
+font in the PDF so long as it has been pre-loaded or is accessible to dompdf and
+reference in CSS @font-face rules. See the
+[font overview](https://github.com/dompdf/dompdf/wiki/About-Fonts-and-Character-Encoding)
+for more information on how to use fonts.
+
+The [DejaVu TrueType fonts](https://dejavu-fonts.github.io/) have been pre-installed
+to give dompdf decent Unicode character coverage by default. To use the DejaVu
+fonts reference the font in your stylesheet, e.g. `body { font-family: DejaVu
+Sans; }` (for DejaVu Sans). The following DejaVu 2.34 fonts are available:
+DejaVu Sans, DejaVu Serif, and DejaVu Sans Mono.
+
+## Easy Installation
+
+### Install with composer
+
+To install with [Composer](https://getcomposer.org/), simply require the
+latest version of this package.
+
+```bash
+composer require dompdf/dompdf
+```
+
+Make sure that the autoload file from Composer is loaded.
+
+```php
+// somewhere early in your project's loading, require the Composer autoloader
+// see: http://getcomposer.org/doc/00-intro.md
+require 'vendor/autoload.php';
+
+```
+
+### Download and install
+
+Download a packaged archive of dompdf and extract it into the
+directory where dompdf will reside
+
+ * You can download stable copies of dompdf from
+ https://github.com/dompdf/dompdf/releases
+ * Or download a nightly (the latest, unreleased code) from
+ http://eclecticgeek.com/dompdf
+
+Use the packaged release autoloader to load dompdf, libraries,
+and helper functions in your PHP:
+
+```php
+// include autoloader
+require_once 'dompdf/autoload.inc.php';
+```
+
+Note: packaged releases are named according using semantic
+versioning (_dompdf_MAJOR-MINOR-PATCH.zip_). So the 1.0.0
+release would be dompdf_1-0-0.zip. This is the only download
+that includes the autoloader for Dompdf and all its dependencies.
+
+### Install with git
+
+From the command line, switch to the directory where dompdf will
+reside and run the following commands:
+
+```sh
+git clone https://github.com/dompdf/dompdf.git
+cd dompdf/lib
+
+git clone https://github.com/PhenX/php-font-lib.git php-font-lib
+cd php-font-lib
+git checkout 0.5.1
+cd ..
+
+git clone https://github.com/PhenX/php-svg-lib.git php-svg-lib
+cd php-svg-lib
+git checkout v0.3.2
+cd ..
+
+git clone https://github.com/sabberworm/PHP-CSS-Parser.git php-css-parser
+cd php-css-parser
+git checkout 8.1.0
+```
+
+Require dompdf and it's dependencies in your PHP.
+For details see the [autoloader in the utils project](https://github.com/dompdf/utils/blob/master/autoload.inc.php).
+
+## Quick Start
+
+Just pass your HTML in to dompdf and stream the output:
+
+```php
+// reference the Dompdf namespace
+use Dompdf\Dompdf;
+
+// instantiate and use the dompdf class
+$dompdf = new Dompdf();
+$dompdf->loadHtml('hello world');
+
+// (Optional) Setup the paper size and orientation
+$dompdf->setPaper('A4', 'landscape');
+
+// Render the HTML as PDF
+$dompdf->render();
+
+// Output the generated PDF to Browser
+$dompdf->stream();
+```
+
+### Setting Options
+
+Set options during dompdf instantiation:
+
+```php
+use Dompdf\Dompdf;
+use Dompdf\Options;
+
+$options = new Options();
+$options->set('defaultFont', 'Courier');
+$dompdf = new Dompdf($options);
+```
+
+or at run time
+
+```php
+use Dompdf\Dompdf;
+
+$dompdf = new Dompdf();
+$options = $dompdf->getOptions();
+$options->setDefaultFont('Courier');
+$dompdf->setOptions($options);
+```
+
+See [Dompdf\Options](src/Options.php) for a list of available options.
+
+### Resource Reference Requirements
+
+In order to protect potentially sensitive information Dompdf imposes
+restrictions on files referenced from the local file system or the web.
+
+Files accessed through web-based protocols have the following requirements:
+ * The Dompdf option "isRemoteEnabled" must be set to "true"
+ * PHP must either have the curl extension enabled or the
+ allow_url_fopen setting set to true
+
+Files accessed through the local file system have the following requirement:
+ * The file must fall within the path(s) specified for the Dompdf "chroot" option
+
+## Limitations (Known Issues)
+
+ * Table cells are not pageable, meaning a table row must fit on a single page.
+ * Elements are rendered on the active page when they are parsed.
+ * Embedding "raw" SVG's (`

+# HTML5-PHP
+
+HTML5 is a standards-compliant HTML5 parser and writer written entirely in PHP.
+It is stable and used in many production websites, and has
+well over [five million downloads](https://packagist.org/packages/masterminds/html5).
+
+HTML5 provides the following features.
+
+- An HTML5 serializer
+- Support for PHP namespaces
+- Composer support
+- Event-based (SAX-like) parser
+- A DOM tree builder
+- Interoperability with [QueryPath](https://github.com/technosophos/querypath)
+- Runs on **PHP** 5.3.0 or newer
+
+[](https://travis-ci.org/Masterminds/html5-php)
+[](https://packagist.org/packages/masterminds/html5)
+[](https://scrutinizer-ci.com/g/Masterminds/html5-php/?branch=master)
+[](https://scrutinizer-ci.com/g/Masterminds/html5-php/?branch=master)
+[](https://masterminds.github.io/stability/sustained.html)
+
+## Installation
+
+Install HTML5-PHP using [composer](http://getcomposer.org/).
+
+By adding the `masterminds/html5` dependency to your `composer.json` file:
+
+```json
+{
+ "require" : {
+ "masterminds/html5": "^2.0"
+ },
+}
+```
+
+By invoking require command via composer executable:
+
+```bash
+composer require masterminds/html5
+```
+
+## Basic Usage
+
+HTML5-PHP has a high-level API and a low-level API.
+
+Here is how you use the high-level `HTML5` library API:
+
+```php
+
+
+ TEST
+
+
+ Hello World
+ This is a test of the HTML5 parser.
+
+
+HERE;
+
+// Parse the document. $dom is a DOMDocument.
+$html5 = new HTML5();
+$dom = $html5->loadHTML($html);
+
+// Render it as HTML5:
+print $html5->saveHTML($dom);
+
+// Or save it to a file:
+$html5->save($dom, 'out.html');
+```
+
+The `$dom` created by the parser is a full `DOMDocument` object. And the
+`save()` and `saveHTML()` methods will take any DOMDocument.
+
+### Options
+
+It is possible to pass in an array of configuration options when loading
+an HTML5 document.
+
+```php
+// An associative array of options
+$options = array(
+ 'option_name' => 'option_value',
+);
+
+// Provide the options to the constructor
+$html5 = new HTML5($options);
+
+$dom = $html5->loadHTML($html);
+```
+
+The following options are supported:
+
+* `encode_entities` (boolean): Indicates that the serializer should aggressively
+ encode characters as entities. Without this, it only encodes the bare
+ minimum.
+* `disable_html_ns` (boolean): Prevents the parser from automatically
+ assigning the HTML5 namespace to the DOM document. This is for
+ non-namespace aware DOM tools.
+* `target_document` (\DOMDocument): A DOM document that will be used as the
+ destination for the parsed nodes.
+* `implicit_namespaces` (array): An assoc array of namespaces that should be
+ used by the parser. Name is tag prefix, value is NS URI.
+
+## The Low-Level API
+
+This library provides the following low-level APIs that you can use to
+create more customized HTML5 tools:
+
+- A SAX-like event-based parser that you can hook into for special kinds
+of parsing.
+- A flexible error-reporting mechanism that can be tuned to document
+syntax checking.
+- A DOM implementation that uses PHP's built-in DOM library.
+
+The unit tests exercise each piece of the API, and every public function
+is well-documented.
+
+### Parser Design
+
+The parser is designed as follows:
+
+- The `Scanner` handles scanning on behalf of the parser.
+- The `Tokenizer` requests data off of the scanner, parses it, clasifies
+it, and sends it to an `EventHandler`. It is a *recursive descent parser.*
+- The `EventHandler` receives notifications and data for each specific
+semantic event that occurs during tokenization.
+- The `DOMBuilder` is an `EventHandler` that listens for tokenizing
+events and builds a document tree (`DOMDocument`) based on the events.
+
+### Serializer Design
+
+The serializer takes a data structure (the `DOMDocument`) and transforms
+it into a character representation -- an HTML5 document.
+
+The serializer is broken into three parts:
+
+- The `OutputRules` contain the rules to turn DOM elements into strings. The
+rules are an implementation of the interface `RulesInterface` allowing for
+different rule sets to be used.
+- The `Traverser`, which is a special-purpose tree walker. It visits
+each node node in the tree and uses the `OutputRules` to transform the node
+into a string.
+- `HTML5` manages the `Traverser` and stores the resultant data
+in the correct place.
+
+The serializer (`save()`, `saveHTML()`) follows the
+[section 8.9 of the HTML 5.0 spec](http://www.w3.org/TR/2012/CR-html5-20121217/syntax.html#serializing-html-fragments).
+So tags are serialized according to these rules:
+
+- A tag with children: <foo>CHILDREN</foo>
+- A tag that cannot have content: <foo> (no closing tag)
+- A tag that could have content, but doesn't: <foo></foo>
+
+## Known Issues (Or, Things We Designed Against the Spec)
+
+Please check the issue queue for a full list, but the following are
+issues known issues that are not presently on the roadmap:
+
+- Namespaces: HTML5 only [supports a selected list of namespaces](http://www.w3.org/TR/html5/infrastructure.html#namespaces)
+ and they do not operate in the same way as XML namespaces. A `:` has no special
+ meaning.
+ By default the parser does not support XML style namespaces via `:`;
+ to enable the XML namespaces see the [XML Namespaces section](#xml-namespaces)
+- Scripts: This parser does not contain a JavaScript or a CSS
+ interpreter. While one may be supplied, not all features will be
+ supported.
+- Rentrance: The current parser is not re-entrant. (Thus you can't pause
+ the parser to modify the HTML string mid-parse.)
+- Validation: The current tree builder is **not** a validating parser.
+ While it will correct some HTML, it does not check that the HTML
+ conforms to the standard. (Should you wish, you can build a validating
+ parser by extending DOMTree or building your own EventHandler
+ implementation.)
+ * There is limited support for insertion modes.
+ * Some autocorrection is done automatically.
+ * Per the spec, many legacy tags are admitted and correctly handled,
+ even though they are technically not part of HTML5.
+- Attribute names and values: Due to the implementation details of the
+ PHP implementation of DOM, attribute names that do not follow the
+ XML 1.0 standard are not inserted into the DOM. (Effectively, they
+ are ignored.) If you've got a clever fix for this, jump in!
+- Processor Instructions: The HTML5 spec does not allow processor
+ instructions. We do. Since this is a server-side library, we think
+ this is useful. And that means, dear reader, that in some cases you
+ can parse the HTML from a mixed PHP/HTML document. This, however,
+ is an incidental feature, not a core feature.
+- HTML manifests: Unsupported.
+- PLAINTEXT: Unsupported.
+- Adoption Agency Algorithm: Not yet implemented. (8.2.5.4.7)
+
+## XML Namespaces
+
+To use XML style namespaces you have to configure well the main `HTML5` instance.
+
+```php
+use Masterminds\HTML5;
+$html = new HTML5(array(
+ "xmlNamespaces" => true
+));
+
+$dom = $html->loadHTML('.");
+ $ele = $this->doc->createElement('invalid');
+ }
+
+ if (Elements::isA($lname, Elements::BLOCK_ONLY_INLINE)) {
+ $this->onlyInline = $lname;
+ }
+
+ // When we add some namespacess, we have to track them. Later, when "endElement" is invoked, we have to remove them.
+ // When we are on a void tag, we do not need to care about namesapce nesting.
+ if ($pushes > 0 && !Elements::isA($name, Elements::VOID_TAG)) {
+ // PHP tends to free the memory used by DOM,
+ // to avoid spl_object_hash collisions whe have to avoid garbage collection of $ele storing it into $pushes
+ // see https://bugs.php.net/bug.php?id=67459
+ $this->pushes[spl_object_hash($ele)] = array($pushes, $ele);

+The serializer roughly follows sections _8.1 Writing HTML documents_ and section
+_8.3 Serializing HTML fragments_ by converting DOMDocument, DOMDocumentFragment,
+and DOMNodeList into HTML5.
+
+ [ HTML5 ] // Interface for saving.
+ ||
+ [ Traverser ] // Walk the DOM
+ ||
+ [ Rules ] // Convert DOM elements into strings.
+ ||
+ [ HTML5 ] // HTML5 document or fragment in text.
+
+
+## HTML5 Class
+
+Provides the top level interface for saving.
+
+## The Traverser
+
+Walks the DOM finding each element and passing it off to the output rules to
+convert to HTML5.
+
+## Output Rules
+
+The output rules are defined in the RulesInterface which can have multiple
+implementations. Currently, the OutputRules is the default implementation that
+converts a DOM as is into HTML5.
+
+## HTML5 String
+
+The output of the process it HTML5 as a string or saved to a file.

+
+# PHP Font Lib
+
+This library can be used to:
+ * Read TrueType, OpenType (with TrueType glyphs), WOFF font files
+ * Extract basic info (name, style, etc)
+ * Extract advanced info (horizontal metrics, glyph names, glyph shapes, etc)
+ * Make an Adobe Font Metrics (AFM) file from a font
+
+You can find a demo GUI [here](http://pxd.me/php-font-lib/www/font_explorer.html).
+
+This project was initiated by the need to read font files in the [DOMPDF project](https://github.com/dompdf/dompdf).
+
+Usage Example
+-------------
+
+```
+$font = \FontLib\Font::load('../../fontfile.ttf');
+$font->parse(); // for getFontWeight() to work this call must be done first!
+echo $font->getFontName() .'

+# Revision History
+
+## 8.4.0
+
+### Features
+
+* Support for PHP 8.x
+* PHPDoc annotations
+* Allow usage of CSS variables inside color functions (by parsing them as regular functions)
+* Use PSR-12 code style
+* *No deprecations*
+
+### Bugfixes
+
+* Improved handling of whitespace in `calc()`
+* Fix parsing units whose prefix is also a valid unit, like `vmin`
+* Allow passing an object to `CSSList#replace`
+* Fix PHP 7.3 warnings
+* Correctly parse keyframes with `%`
+* Don’t convert large numbers to scientific notation
+* Allow a file to end after an `@import`
+* Preserve case of CSS variables as specced
+* Allow identifiers to use escapes the same way as strings
+* No longer use `eval` for the comparison in `getSelectorsBySpecificity`, in case it gets passed untrusted input (CVE-2020-13756). Also fixed in 8.3.1, 8.2.1, 8.1.1, 8.0.1, 7.0.4, 6.0.2, 5.2.1, 5.1.3, 5.0.9, 4.0.1, 3.0.1, 2.0.1, 1.0.1.
+* Prevent an infinite loop when parsing invalid grid line names
+* Remove invalid unit `vm`
+* Retain rule order after expanding shorthands
+
+### Backwards-incompatible changes
+
+* PHP ≥ 5.6 is now required
+* HHVM compatibility target dropped
+
+## 8.3.0 (2019-02-22)
+
+* Refactor parsing logic to mostly reside in the class files whose data structure is to be parsed (this should eventually allow us to unit-test specific parts of the parsing logic individually).
+* Fix error in parsing `calc` expessions when the first operand is a negative number, thanks to @raxbg.
+* Support parsing CSS4 colors in hex notation with alpha values, thanks to @raxbg.
+* Swallow more errors in lenient mode, thanks to @raxbg.
+* Allow specifying arbitrary strings to output before and after declaration blocks, thanks to @westonruter.
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 8.2.0 (2018-07-13)
+
+* Support parsing `calc()`, thanks to @raxbg.
+* Support parsing grid-lines, again thanks to @raxbg.
+* Support parsing legacy IE filters (`progid:`) in lenient mode, thanks to @FMCorz
+* Performance improvements parsing large files, again thanks to @FMCorz
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 8.1.0 (2016-07-19)
+
+* Comments are no longer silently ignored but stored with the object with which they appear (no render support, though). Thanks to @FMCorz.
+* The IE hacks using `\0` and `\9` can now be parsed (and rendered) in lenient mode. Thanks (again) to @FMCorz.
+* Media queries with or without spaces before the query are parsed. Still no *real* parsing support, though. Sorry…
+* PHPUnit is now listed as a dev-dependency in composer.json.
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 8.0.0 (2016-06-30)
+
+* Store source CSS line numbers in tokens and parsing exceptions.
+* *No deprecations*
+
+### Backwards-incompatible changes
+
+* Unrecoverable parser errors throw an exception of type `Sabberworm\CSS\Parsing\SourceException` instead of `\Exception`.
+
+## 7.0.3 (2016-04-27)
+
+* Fixed parsing empty CSS when multibyte is off
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 7.0.2 (2016-02-11)
+
+* 150 time performance boost thanks to @[ossinkine](https://github.com/ossinkine)
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 7.0.1 (2015-12-25)
+
+* No more suppressed `E_NOTICE`
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 7.0.0 (2015-08-24)
+
+* Compatibility with PHP 7. Well timed, eh?
+* *No deprecations*
+
+### Backwards-incompatible changes
+
+* The `Sabberworm\CSS\Value\String` class has been renamed to `Sabberworm\CSS\Value\CSSString`.
+
+## 6.0.1 (2015-08-24)
+
+* Remove some declarations in interfaces incompatible with PHP 5.3 (< 5.3.9)
+* *No deprecations*
+
+## 6.0.0 (2014-07-03)
+
+* Format output using Sabberworm\CSS\OutputFormat
+* *No backwards-incompatible changes*
+
+### Deprecations
+
+* The parse() method replaces __toString with an optional argument (instance of the OutputFormat class)
+
+## 5.2.0 (2014-06-30)
+
+* Support removing a selector from a declaration block using `$oBlock->removeSelector($mSelector)`
+* Introduce a specialized exception (Sabberworm\CSS\Parsing\OuputException) for exceptions during output rendering
+
+* *No deprecations*
+
+#### Backwards-incompatible changes
+
+* Outputting a declaration block that has no selectors throws an OuputException instead of outputting an invalid ` {…}` into the CSS document.
+
+## 5.1.2 (2013-10-30)
+
+* Remove the use of consumeUntil in comment parsing. This makes it possible to parse comments such as `/** Perfectly valid **/`
+* Add fr relative size unit
+* Fix some issues with HHVM
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 5.1.1 (2013-10-28)
+
+* Updated CHANGELOG.md to reflect changes since 5.0.4
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 5.1.0 (2013-10-24)
+
+* Performance enhancements by Michael M Slusarz
+* More rescue entry points for lenient parsing (unexpected tokens between declaration blocks and unclosed comments)
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 5.0.8 (2013-08-15)
+
+* Make default settings’ multibyte parsing option dependent on whether or not the mbstring extension is actually installed.
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 5.0.7 (2013-08-04)
+
+* Fix broken decimal point output optimization
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 5.0.6 (2013-05-31)
+
+* Fix broken unit test
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 5.0.5 (2013-04-17)
+
+* Initial support for lenient parsing (setting this parser option will catch some exceptions internally and recover the parser’s state as neatly as possible).
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 5.0.4 (2013-03-21)
+
+* Don’t output floats with locale-aware separator chars
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 5.0.3 (2013-03-21)
+
+* More size units recognized
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 5.0.2 (2013-03-21)
+
+* CHANGELOG.md file added to distribution
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 5.0.1 (2013-03-20)
+
+* Internal cleanup
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 5.0.0 (2013-03-20)
+
+* Correctly parse all known CSS 3 units (including Hz and kHz).
+* Output RGB colors in short (#aaa or #ababab) notation
+* Be case-insensitive when parsing identifiers.
+* *No deprecations*
+
+### Backwards-incompatible changes
+
+* `Sabberworm\CSS\Value\Color`’s `__toString` method overrides `CSSList`’s to maybe return something other than `type(value, …)` (see above).
+
+## 4.0.0 (2013-03-19)
+
+* Support for more @-rules
+* Generic interface `Sabberworm\CSS\Property\AtRule`, implemented by all @-rule classes
+* *No deprecations*
+
+### Backwards-incompatible changes
+
+* `Sabberworm\CSS\RuleSet\AtRule` renamed to `Sabberworm\CSS\RuleSet\AtRuleSet`
+* `Sabberworm\CSS\CSSList\MediaQuery` renamed to `Sabberworm\CSS\RuleSet\CSSList\AtRuleBlockList` with differing semantics and API (which also works for other block-list-based @-rules like `@supports`).
+
+## 3.0.0 (2013-03-06)
+
+* Support for lenient parsing (on by default)
+* *No deprecations*
+
+### Backwards-incompatible changes
+
+* All properties (like whether or not to use `mb_`-functions, which default charset to use and – new – whether or not to be forgiving when parsing) are now encapsulated in an instance of `Sabberworm\CSS\Settings` which can be passed as the second argument to `Sabberworm\CSS\Parser->__construct()`.
+* Specifying a charset as the second argument to `Sabberworm\CSS\Parser->__construct()` is no longer supported. Use `Sabberworm\CSS\Settings::create()->withDefaultCharset('some-charset')` instead.
+* Setting `Sabberworm\CSS\Parser->bUseMbFunctions` has no effect. Use `Sabberworm\CSS\Settings::create()->withMultibyteSupport(true/false)` instead.
+* `Sabberworm\CSS\Parser->parse()` may throw a `Sabberworm\CSS\Parsing\UnexpectedTokenException` when in strict parsing mode.
+
+## 2.0.0 (2013-01-29)
+
+* Allow multiple rules of the same type per rule set
+
+### Backwards-incompatible changes
+
+* `Sabberworm\CSS\RuleSet->getRules()` returns an index-based array instead of an associative array. Use `Sabberworm\CSS\RuleSet->getRulesAssoc()` (which eliminates duplicate rules and lets the later rule of the same name win).
+* `Sabberworm\CSS\RuleSet->removeRule()` works as it did before except when passed an instance of `Sabberworm\CSS\Rule\Rule`, in which case it would only remove the exact rule given instead of all the rules of the same type. To get the old behaviour, use `Sabberworm\CSS\RuleSet->removeRule($oRule->getRule()`;
+
+## 1.0
+
+Initial release of a stable public API.
+
+## 0.9
+
+Last version not to use PSR-0 project organization semantics.

+# PHP CSS Parser
+
+[](https://github.com/sabberworm/PHP-CSS-Parser/actions/)
+
+A Parser for CSS Files written in PHP. Allows extraction of CSS files into a data structure, manipulation of said structure and output as (optimized) CSS.
+
+## Usage
+
+### Installation using Composer
+
+```bash
+composer require sabberworm/php-css-parser
+```
+
+### Extraction
+
+To use the CSS Parser, create a new instance. The constructor takes the following form:
+
+```php
+new \Sabberworm\CSS\Parser($css);
+```
+
+To read a file, for example, you’d do the following:
+
+```php
+$parser = new \Sabberworm\CSS\Parser(file_get_contents('somefile.css'));
+$cssDocument = $parser->parse();
+```
+
+The resulting CSS document structure can be manipulated prior to being output.
+
+### Options
+
+#### Charset
+
+The charset option is used only if no `@charset` declaration is found in the CSS file. UTF-8 is the default, so you won’t have to create a settings object at all if you don’t intend to change that.
+
+```php
+$settings = \Sabberworm\CSS\Settings::create()
+ ->withDefaultCharset('windows-1252');
+$parser = new \Sabberworm\CSS\Parser($css, $settings);
+```
+
+#### Strict parsing
+
+To have the parser choke on invalid rules, supply a thusly configured `\Sabberworm\CSS\Settings` object:
+
+```php
+$parser = new \Sabberworm\CSS\Parser(
+ file_get_contents('somefile.css'),
+ \Sabberworm\CSS\Settings::create()->beStrict()
+);
+```
+
+#### Disable multibyte functions
+
+To achieve faster parsing, you can choose to have PHP-CSS-Parser use regular string functions instead of `mb_*` functions. This should work fine in most cases, even for UTF-8 files, as all the multibyte characters are in string literals. Still it’s not recommended using this with input you have no control over as it’s not thoroughly covered by test cases.
+
+```php
+$settings = \Sabberworm\CSS\Settings::create()->withMultibyteSupport(false);
+$parser = new \Sabberworm\CSS\Parser($css, $settings);
+```
+
+### Manipulation
+
+The resulting data structure consists mainly of five basic types: `CSSList`, `RuleSet`, `Rule`, `Selector` and `Value`. There are two additional types used: `Import` and `Charset`, which you won’t use often.
+
+#### CSSList
+
+`CSSList` represents a generic CSS container, most likely containing declaration blocks (rule sets with a selector), but it may also contain at-rules, charset declarations, etc. `CSSList` has the following concrete subtypes:
+
+* `Document` – representing the root of a CSS file.
+* `MediaQuery` – represents a subsection of a `CSSList` that only applies to an output device matching the contained media query.
+
+To access the items stored in a `CSSList` – like the document you got back when calling `$parser->parse()` –, use `getContents()`, then iterate over that collection and use instanceof to check whether you’re dealing with another `CSSList`, a `RuleSet`, a `Import` or a `Charset`.
+
+To append a new item (selector, media query, etc.) to an existing `CSSList`, construct it using the constructor for this class and use the `append($oItem)` method.
+
+#### RuleSet
+
+`RuleSet` is a container for individual rules. The most common form of a rule set is one constrained by a selector. The following concrete subtypes exist:
+
+* `AtRuleSet` – for generic at-rules which do not match the ones specifically mentioned like `@import`, `@charset` or `@media`. A common example for this is `@font-face`.
+* `DeclarationBlock` – a `RuleSet` constrained by a `Selector`; contains an array of selector objects (comma-separated in the CSS) as well as the rules to be applied to the matching elements.
+
+Note: A `CSSList` can contain other `CSSList`s (and `Import`s as well as a `Charset`), while a `RuleSet` can only contain `Rule`s.
+
+If you want to manipulate a `RuleSet`, use the methods `addRule(Rule $rule)`, `getRules()` and `removeRule($rule)` (which accepts either a `Rule` instance or a rule name; optionally suffixed by a dash to remove all related rules).
+
+#### Rule
+
+`Rule`s just have a key (the rule) and a value. These values are all instances of a `Value`.
+
+#### Value
+
+`Value` is an abstract class that only defines the `render` method. The concrete subclasses for atomic value types are:
+
+* `Size` – consists of a numeric `size` value and a unit.
+* `Color` – colors can be input in the form #rrggbb, #rgb or schema(val1, val2, …) but are always stored as an array of ('s' => val1, 'c' => val2, 'h' => val3, …) and output in the second form.
+* `CSSString` – this is just a wrapper for quoted strings to distinguish them from keywords; always output with double quotes.
+* `URL` – URLs in CSS; always output in URL("") notation.
+
+There is another abstract subclass of `Value`, `ValueList`. A `ValueList` represents a lists of `Value`s, separated by some separation character (mostly `,`, whitespace, or `/`). There are two types of `ValueList`s:
+
+* `RuleValueList` – The default type, used to represent all multi-valued rules like `font: bold 12px/3 Helvetica, Verdana, sans-serif;` (where the value would be a whitespace-separated list of the primitive value `bold`, a slash-separated list and a comma-separated list).
+* `CSSFunction` – A special kind of value that also contains a function name and where the values are the function’s arguments. Also handles equals-sign-separated argument lists like `filter: alpha(opacity=90);`.
+
+#### Convenience methods
+
+There are a few convenience methods on Document to ease finding, manipulating and deleting rules:
+
+* `getAllDeclarationBlocks()` – does what it says; no matter how deeply nested your selectors are. Aliased as `getAllSelectors()`.
+* `getAllRuleSets()` – does what it says; no matter how deeply nested your rule sets are.
+* `getAllValues()` – finds all `Value` objects inside `Rule`s.
+
+## To-Do
+
+* More convenience methods (like `selectorsWithElement($sId/Class/TagName)`, `attributesOfType($type)`, `removeAttributesOfType($type)`)
+* Real multibyte support. Currently, only multibyte charsets whose first 255 code points take up only one byte and are identical with ASCII are supported (yes, UTF-8 fits this description).
+* Named color support (using `Color` instead of an anonymous string literal)
+
+## Use cases
+
+### Use `Parser` to prepend an ID to all selectors
+
+```php
+$myId = "#my_id";
+$parser = new \Sabberworm\CSS\Parser($css);
+$cssDocument = $parser->parse();
+foreach ($cssDocument->getAllDeclarationBlocks() as $block) {
+ foreach ($block->getSelectors() as $selector) {
+ // Loop over all selector parts (the comma-separated strings in a
+ // selector) and prepend the ID.
+ $selector->setSelector($myId.' '.$selector->getSelector());
+ }
+}
+```
+
+### Shrink all absolute sizes to half
+
+```php
+$parser = new \Sabberworm\CSS\Parser($css);
+$cssDocument = $parser->parse();
+foreach ($cssDocument->getAllValues() as $value) {
+ if ($value instanceof CSSSize && !$value->isRelative()) {
+ $value->setSize($value->getSize() / 2);
+ }
+}
+```
+
+### Remove unwanted rules
+
+```php
+$parser = new \Sabberworm\CSS\Parser($css);
+$cssDocument = $parser->parse();
+foreach($cssDocument->getAllRuleSets() as $oRuleSet) {
+ // Note that the added dash will make this remove all rules starting with
+ // `font-` (like `font-size`, `font-weight`, etc.) as well as a potential
+ // `font-rule`.
+ $oRuleSet->removeRule('font-');
+ $oRuleSet->removeRule('cursor');
+}
+```
+
+### Output
+
+To output the entire CSS document into a variable, just use `->render()`:
+
+```php
+$parser = new \Sabberworm\CSS\Parser(file_get_contents('somefile.css'));
+$cssDocument = $parser->parse();
+print $cssDocument->render();
+```
+
+If you want to format the output, pass an instance of type `\Sabberworm\CSS\OutputFormat`:
+
+```php
+$format = \Sabberworm\CSS\OutputFormat::create()
+ ->indentWithSpaces(4)->setSpaceBetweenRules("\n");
+print $cssDocument->render($format);
+```
+
+Or use one of the predefined formats:
+
+```php
+print $cssDocument->render(Sabberworm\CSS\OutputFormat::createPretty());
+print $cssDocument->render(Sabberworm\CSS\OutputFormat::createCompact());
+```
+
+To see what you can do with output formatting, look at the tests in `tests/OutputFormatTest.php`.
+
