Cascading Style Sheets (CSS) is a style sheet language used for describing
the presentation semantics (the look and formatting) of a document written
in a markup language. Its most common application is to style web pages
written in HTML and XHTML, but the language can also be applied to any kind
of XML document, including plain XML, SVG and XUL.
