Cascading Style Sheets (
CSS) is a
style sheet language used for describing the
presentation of a document written in a
markup language. Although most often used to set the visual style of
web pages and user interfaces written in
HTML and
XHTML, the language can be applied to any
XML document, including
plain XML,
SVG and
XUL, and is applicable to rendering in
speech, or on other media. Along with HTML and
JavaScript, CSS is a cornerstone technology used by most websites to create visually engaging webpages, user interfaces for
web applications, and user interfaces for many mobile applications.
