Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a NOUN written in a markup language such as HTML or XML. CSS is a cornerstone NOUN of the World Wide NOUN, alongside HTML and JavaScript.
CSS is designed to VERB presentation and content, including layout, colors, and PLURAL NOUN. This can improve content accessibility, provide more NOUN, enable ADJECTIVE web pages to share PLURAL NOUN, and enable the .css file to be PAST TENSE VERB to improve the page load speed.
Separation of formatting and content also makes it ADJECTIVE to present the same markup page in ADJECTIVE styles for different rendering methods, such as on-screen, in print, by voice, and on ADJECTIVE devices. CSS also has PLURAL NOUN for alternate formatting if the content is accessed on a mobile NOUN.
The name cascading comes from the specified ADJECTIVE scheme to determine which style rule applies if more than one rule matches a particular NOUN. This cascading priority scheme is ADJECTIVE.
The CSS specifications are maintained by the World Wide Web NOUN.
