Learn

You can learn CSS from articles in English and other languages, read books about CSS, or attend CSS events and workshops.

Most Web browsers today support CSS, as do other software. Although you can write CSS with a simple text editor, many tools exist to make it even easier.

Test

Good test suites drive interoperability. They’re a key part of making sure Web standards are implemented correctly and consistently. The W3C hosts the official CSS Conformance Test Suites here. Many of these test suites are still works in progress.

You can help us drive CSS interoperability on the Web by reporting errors and contributing new or improved tests.

Discuss

If you want to talk CSS, the css-discuss mailing list, CSS Creator Web forums, and c.i.w.a.s. Usenet newsgroup are all devoted to the practical use of Cascading Style Sheets.

To keep up with the CSS Working Group's latest announcements, discussion topics, and resolutions you can follow the CSSWG weblog, which is aggregated with other CSS-focused streams on The Future of Style.

Finally, detailed technical discussion about the CSS specifications takes place on the publicly-archived www-style mailing list.
