Cascading Style Sheets\u00a0(CSS) is a\u00a0style sheet language<\/a>\u00a0used for describing the\u00a0presentation<\/a>\u00a0of a document written in a\u00a0markup language<\/a>\u00a0such as\u00a0HTML<\/a>\u00a0or\u00a0XML<\/a>\u00a0(including XML dialects such as\u00a0SVG<\/a>,\u00a0MathML<\/a>\u00a0or\u00a0XHTML<\/a>).<\/p>\n

CSS is a cornerstone technology of the World Wide Web, alongside HTML and JavaScript.<\/p>\n

CSS is designed to enable the separation of content and presentation, including layout, colors, and fonts. This separation can improve content accessibility; provide more flexibility and control in the specification of presentation characteristics; enable multiple web pages to share formatting by specifying the relevant CSS in a separate .css file, which reduces complexity and repetition in the structural content; and enable the .css file to be cached to improve the page load speed between the pages that share the file and its formatting.<\/p>\n

Separation of formatting and content also makes it feasible to present the same markup page in different styles for different rendering methods, such as on-screen, in print, by voice (via speech-based browser or screen reader), and on Braille-based tactile devices. CSS also has rules for alternate formatting if the content is accessed on a mobile device.<\/p>\n

The name cascading comes from the specified priority scheme to determine which style rule applies if more than one rule matches a particular element. This cascading priority scheme is predictable.<\/p>\n

The CSS specifications are maintained by the World Wide Web Consortium (W3C). Internet media type (MIME type) text\/css is registered for use with CSS by RFC 2318 (March 1998). The W3C operates a free CSS validation service for CSS documents.<\/p>\n

In addition to HTML, other markup languages support the use of CSS including XHTML, plain XML, SVG, and XUL.<\/p>\n","protected":false},"excerpt":{"rendered":"
