Cascading Style Sheets (CSS) is a style sheet language used to describe the presentation semantics
(that is, 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 SVG and XUL.
CSS is designed primarily to enable the separation of document content (written in
HTML or a similar markup
language) from document presentation, including elements such as the layout, colors, and fonts. This
separation can improve content accessibility, provide more flexibility and control in the specification
of presentation characteristics, enable multiple pages to share formatting, and reduce complexity and
repetition in the structural content (such as by allowing for table less web design). CSS can also allow
the same markup page to be presented in different styles for different rendering methods, such as on-screen,
in print, by voice (when read out by a speech-based browser or screen reader) and on Braille-based,
tactile devices. While the author of a document typically links that document to a CSS style sheet,
readers can use a different style sheet, perhaps one on their own computer, to override the one the author
