Abstract

This specification defines Cascading Style Sheets level 2 (CSS 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.

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 the CSS 2.1 and CSS2 (1998) specifications. See appendix C of this document for changes from CSS 2.1, and appendix C of CSS 2.1 for changes from CSS2 (1998) (noting that certain CSS2 (1998) features were removed from CSS 2 in CSS 2.1). All future specifications should refer to CSS 2.2 when referring to CSS level 2; if they wish to reference features from CSS2 (1998) dropped in later revisions they should reference the latest applicable CSS module.
