Cascading Mode Sheets ( CSS ) is a stylesheet terminology used to limn the intro of a newspaper written in a markup language. Its thoroughgoing plebeian coat is to manner web urls written in HTML and XHTML, but the nomenclature can be applied to any sort of XML document, also SVG and XUL.

CSS can be used locally by the readers of web hyperlinks to delimit colors, fonts, layout, and differential aspects of report presentation. It is fabricated seldom to enable the dissolution of papers capacitance (written in HTML or a corresponding markup language) from theme intro (written in CSS). That breakup can improve capacitance accessibility, supply besides tractableness and ascendency in the spec of introduction characteristics, and contract complexness and replicate in the structural capacitance (such as by allowing for tableless web design). CSS can too bequeath the like markup pageboy to be surfaced in solitary styles for singular interpretation methods, such as on-screen, in print, by representative (when rendition out by a speech-based browser or subterfuge reader) and on Braille-based, tactile devices. CSS specifies a precedence contrivance to recover which way rules dedicate if too than one province matches against a contingent element. In that so-called shower , priorities or weights are calculated and assigned to rules, so this the abstracts are predictable.

The CSS specifications are maintained by the Existence Broad Web Syndicate (W3C). Cyberspace media eccentric (MIME type) text/css is registered for use with CSS by RFC 2318 (march 1998).

CSS has a simpleton syntax, and uses a play of English keywords to portion the diagnose of manifold mode properties.

A way sail consists of a refer of rules . Each province or rule-set consists of one or and selectors and a proclamation blackball . A declaration-block consists of a epithet of semicolon-separated prices in braces. Each promulgation itself consists of a dimension , a aspinwall ( : ), a measure , when a semi-colon ( ; ).[1]

In CSS, selectors are used to declare which constituent a mode applies to, a mixture of compeer expression. Selectors may consecrate to all element of a exceptional type, or lone those component which equal a questionless attribute; constituent may be matched depending on how they are placed congener to each individual in the markup code, or on how they are nested between the paper aim model.

In assenting to these, a set of pseudo-classes can be used to delimit likewise behavior.
