Cascading Style Sheets (CSS) can be considered as a style sheet language which is used for describing the presentation semantics (the look and formatting) of a document written in a markup language. It has been is widely used and popular amongst web developers over the world. CSS is mainly designed 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.
CSS RENDERING METHODS
CSS also allows 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.
