Cascading Style Sheets, ou feuilles de style en cascade.
Les feuilles de style servent à donner une forme aux éléments des pages web, et des documents structurés en général (html, xml). Actuellement, avec les nouvelles normes XHTML, les CSS permettent de séparer le contenu de la forme, permettant ainsi une meilleure accessibilité aux sites puisque le langage html ou xhtml n’est plus utilisé que pour structurer le contenu, le style de présentation étant externalisée dans une feuille de style. Browser support: IE: Internet Explorer, M: Mac IE only, F: Firefox, N: Netscape. W3C: The number in the "W3C" column indicates in which CSS recommendation the property is defined (CSS1 or CSS2).
