CSS
Cascading Style Sheets (CSS) is a style sheet language used to
describe the presentation (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 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 colors,
fonts, and layout. 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 tableless 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 stylesheet, readers can use a different stylesheet, perhaps one
on their own computer, to override the one the author has
specified.
CSS specifies a priority scheme to determine which style rules
apply if more than one rule matches against a particular element.
In this so-called cascade, priorities or weights are calculated and
assigned to rules, so that the results are predictable.
