If you want to follow the development of CSS3, this page is the place to start. Publication descriptions are ordered roughly according to their priority within the working group. (See also the explanation of status codes.) Also available: the index of all CSS properties, by Jens Meiert

A glossary of all specifications produced by the CSS Working Group is also available.

If you want to help

The CSS working group also occasionally writes on a blog. If you react to a blog article, please, send a “pingback.”

Everybody can take part in the discussions on the archived mailing list www-style@w3.org. You can subscribe yourself. This is the preferred place for discussions, since the members of the working group will see them. Please don't use this list for questions of the type "How do I...". Use comp. infosystems. www. authoring. stylesheets ("ciwas") or see "Learning CSS".

If you work for a W3C member organization, you can also read the minutes of the CSS working group and rough drafts before they are published. You can also participate in the working group, but only if you can commit to (on average) 1 day per week. Contact me or your organization's W3C contact person.

A specification is not a manual. There is no excuse for badly written drafts and please complain if you find one. But specs do target a specific audience. J. David Eisenberg has written a useful How to read W3C specs.

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. The CSS1 test suite has been very useful, and still is, not only for people developing software, but also for people looking for examples of each feature. 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.
