CSS

an old reference but a good one

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.

f you are looking for help making the transition to CSS layout (that's Cascading Style Sheets), you've come to the right place.

This is a journey from six years of conventional web design practice to the way we’ll build sites in the future. Only it’s not set in the future. You’re soaking in it.

Most modern browsers support the :hover selector for any html element. This is cool, because it enables you to, for instance, apply a mouseover effect to table rows <tr> using only CSS. IE however, with a market share of > 90%, does not natively support :hover on elements other than links <a>, rendering the entire :hover concept useless. Or does it?

This document specifies level 1 of the Cascading Style Sheet mechanism (CSS1). CSS1 is a simple style sheet mechanism that allows authors and readers to attach style (e.g. fonts, colors and spacing) to HTML documents. The CSS1 language is human readable and writable, and expresses style in common desktop publishing terminology. One of the fundamental features of CSS is that style sheets cascade; authors can attach a preferred style sheet, while the reader may have a personal style sheet to adjust for human or technological handicaps. The rules for resolving conflicts between different style sheets are defined in this specification.

This specification defines Cascading Style Sheets, level 2 (CSS2). CSS2 is a style sheet language that allows authors and users to attach style (e.g., fonts, spacing, and aural cues) to structured documents (e.g., HTML documents and XML applications). By separating the presentation style of documents from the content of documents, CSS2 simplifies Web authoring and site maintenance. CSS2 builds on CSS1 (see [CSS1]) and, with very few exceptions, all valid CSS1 style sheets are valid CSS2 style sheets. CSS2 supports media-specific style sheets so that authors may tailor the presentation of their documents to visual browsers, aural devices, printers, braille devices, handheld devices, etc. This specification also supports content positioning, downloadable fonts, table layout, features for internationalization, automatic counters and numbering, and some properties related to user interface.
