Abstract

This specification defines Cascading Style Sheets level 2 revision 2 (CSS 2.2). CSS is a style sheet language that allows authors and users to attach style (e.g., fonts and spacing) to structured documents (e.g., HTML documents and XML applications). By separating the presentation style of documents from the content of documents, CSS simplifies Web authoring and site maintenance.

CSS 2.2 is the second revision of CSS level 2 [CSS2]. It corrects a few errors in CSS 2.1, the first revision of CSS level 2.

It 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. It also supports content positioning, table layout, features for internationalization and some properties related to user interface.

CSS 2.2 is derived from and is intended to replace CSS 2.1 and CSS2. Some parts of CSS2 are unchanged in CSS 2.2, some parts have been altered, and some parts removed. The removed portions may be used in a future CSS3 specification. Future specs should refer to CSS 2.2 (unless they need features from CSS2 which have been dropped in CSS 2.2, and then they should only reference CSS2 for those features, or preferably reference such feature(s) in the respective CSS3 Module that includes those feature(s)).
