17.7. What's New in CSS2

The CSS Level 2 (http://www.w3.org/TR/REC-CSS2) specification expands significantly on the work done in CSS1. Not surprisingly, it includes dozens of new properties (and pseudo-elements) and a fair number of additional values for existing properties (see the following tables).

CSS2 incorporates and refines the set of properties used for positioning to give designers more control over page layout and DHTML authors the ability to create dynamic motion effects.

It provides more controls over traditional typesetting elements such as widows, orphans, and page breaks. This shows that style sheets are being developed with a mind to developing documents for both HTML display and print output.

CSS2 also introduces properties that give additional control over table element presentation.

As part of the W3C's efforts to make web pages accessible to all users, the latest style sheet specification includes a number of new properties that pertain to the nonvisual display of web pages. These new attributes provide controls for speech-delivery and sound controls.

The following list of new CSS2 elements was compiled and graciously contributed to this book by CSS guru Eric Meyer. It reflects the state of the final CSS2 specification, which was made a W3C Recommendation in May 1998. Unfortunately, as of this writing, no browsers are supporting CSS2 in its entirety, and no promises have been made on when that day will come.
