    What is CSS?

    Cascading Style Sheets (CSS) is a simple mechanism for adding style (e.g., fonts, colors, spacing) to Web documents.

    These pages contain information on how to learn and use CSS and on available software. They also contain news from the CSS working group.

    Join-ing the dis-cus-sion

    The <[email protected]> mailing list is the place for discussing the further development of CSS. (The CSS working group also uses that list for most discussions.) Everybody can subscribe (or unsubscribe, or see instructions.)

    If you work for a W3C member organization, you can also join the working group.

    Soft-ware (Also available as Atom news feed.)

    Nearly all browsers nowadays support CSS and many other applications do, too. To write CSS, you don't need more than a text editor, but there are many tools available that make it even easier.

    Of course, all software has bugs, even after several updates. And some programs are further ahead implementing the latest CSS modules than others. Various sites describe bugs and work-arounds.

    Learn-ing CSS (Also available as Atom news feed.)

    For beginners, Starting with HTML + CSS teaches how to create a style sheet. For a quick introduction to CSS, try chapter 2 of Lie & Bos or Dave Raggett's intro to CSS. Or see examples of styling XML and CSS tips & tricks.

    Another page also has some books, mailing lists and similar fora, and links to other directories.

    The history of CSS is described in chapter?20 of the book Cascading Style Sheets, designing for the Web, by H?kon Wium Lie and Bert Bos (2nd ed., 1999, Addison Wesley, ISBN 0-201-59625-3)
