Cascading Style Sheets (CSS) is a simple mechanism for adding style (e.g. fonts, colors, spacing) to Web documents. For background information on style sheets, see the Web style sheets resource page. Discussions about CSS are carried out on the (archived) mailing list and on comp.infosystems.www.authoring.stylesheets.

CSS Browsers

The easiest way to start experimenting with style sheets is to download one of the browsers that support CSS1. Not all of the browsers below implement the full specification, but releases are coming out fast so this should soon change.

These sources document the level of support in various browsers:

CSS Authoring Tools

Currently, most Web Authoring tools provide some sort of support for CSS style sheets. A ZDnet article described some of them. The list below is far from complete, but contains (in chronological order) all tools that have been reported to us.

CSS Specifications

Cascading Style Sheets, level 1 (CSS1) became a W3C Recommendation in December 1996. It describes the CSS language as well as a simple visual formatting model. CSS2, which became a W3C Recommendation in May 1998, builds on CSS1 and adds support for media-specific style sheets (e.g. printers and aural devices), downloadable fonts, element positioning and tables.

CSS3 is currently under development. You can follow its progress as new drafts are published.

Translations into some languages are available from the CSS1 translations page and the CSS2 translations page. Errata are maintained separately for CSS1 and CSS2.

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