What is CSS?
Cascading Style Sheets (CSS) is a stylesheet language used to
describe the presentation 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 can be used locally by the readers of web pages to define
colors, fonts, layout, and other aspects of document presentation.
It is designed primarily to enable the separation of document
content (written in HTML or a similar markup language) from document
presentation (written in CSS). This separation can improve content
accessibility, provide more flexibility and control in the
specification of presentation characteristics, 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. 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.
