The actual font data needed won't be known until all the style references in the document are parsed. To provide the greatest flexibility, font data must be referenced from the document itself. This tag creates a typed hyperlink between a document and a resource, and is the tag being proposed for linking a style sheet file to a document. This implementation will assist browsers in determining, similar to image data, what resources they are capable of processing and performing. As described above, style sheets are a mechanism for associating fonts with web documents, but they are far more useful than that.
Style sheets provide authors with a great deal of control over the appearance of their documents.
Unfortunately, as the author himself admits, CSS1 as currently defined needs further development for printing. While printers can use nearly all of the defined style sheet properties, certain characteristics, for example margins, should generally be treated differently for printed media than for video display. The tools for bringing high quality printing are within our grasp. Style sheets will address formatting concerns, while font portability solves character set problems and provides authors with the expressiveness they desire. We will continue to partner with standards groups and industry leaders to make these capabilities a reality for all web users.
