Спецификация CSS1

         

We expect to see extensions


We expect to see extensions of CSS in several directions:


    paper: better support for printing HTML documents


  • support for non-visual media: work is in the process to add a list of properties and corresponding values to support speech and braille output


  • color names: the currently supported list may be extended


  • fonts: more precise font specification systems are expected to complement existing CSS1 font properties.


  • values, properties: we expect vendors to propose extensions to the CSS1 set of values and properties. Extending in this direction is trivial for the specification, but interoperability between different UAs is a concern


  • layout language: support for two-dimensional layout in the tradition of desktop publishing packages.


  • other DTDs: CSS1 has some HTML-specific parts (e.g. the special status of the 'CLASS' and 'ID' attributes) but should easily be extended to apply to other DTDs as well.


We do not expect CSS to evolve into:


    a programming language
