CSS current work & how to participate
CSS specifications
This page contains a list of all completed specifications and drafts by the CSS WG (formerly “CSS & FP WG”). If you want to follow the development of CSS3, this is the place to start. You have ideas? Contributions? See “If you want to help” on this page.
About the test suites
The CSS working group intends to spend a lot of time on developing the CSS test suites along with the CSS specifications. By providing a test suite for each module as soon as the module is published, we hope not only that CSS3 implementations will conform to the specification much earlier, but also that people will have an easier time understanding the formal text of the spec.
The test suites have their own archived mailing list public-css-testsuite@w3.org. Please send error reports, test case submissions, and any other questions and comments about the CSS test suites there. Elika Etemad maintains the CSS Testing Wiki with more info for contributors.
Mark-up conventions
The source mark-up of the specifications follows certain conventions (which is useful for automatic processing).
