Cascading Style Sheets (CSS) is a simple mechanism for adding style (e.g. fonts, colors, spacing) to Web documents. Tutorials, books, mailing lists for users, etc. can be found on the learning CSS page. For background information on style sheets, see the Web style sheets page. Discussions about CSS are carried out on the (archived) www-style@w3.org mailing list (and sometimes on the CSS blog) and on comp.infosystems.www.authoring.stylesheets.
