 description: >
     String.prototype.fontsize returns a string of HTML describing a single
     HTML font element. The element's content is the `this` value of the
     function invocation, coerced to a string. If specified, the first argument
     will be coerced to a string, escaped, and set as the element's `size`
     attribute.
