Definition

CSS is a style sheet mechanism that allows authors and readers to attach style (e.g. fonts, colors and spacing) to HTML documents. The CSS 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. There are rules for resolving conflicts between different style sheets. With the help of some JavaScript code one also may offer several stylesheets to an enduser.

Finally CSS is an important component in so called "DHTML" and AJAX. Programming Dynamic Web pages may involve dynamic change of CSS features.
