Cascading Style Sheets

Cascading Style Sheets, better known by the initials CSS is a formatting language that controls the styling of a web page. It is intended to allow you to seperate the presentation (styling) i.e. colours, typefaces and so on from the content and structure of a hypertext document, in much the same way a printing formatter does to the output of a text editor or a word processor.

While it is supposedly agnostic to what sort of markup language is used, it is very much tied to the HTML format and related concepts such as XML. It was originally developed by browser manufacturer Opera.
