Cascading Style Sheets World-Wide Web
(CSS) An extension to HTML to allow styles, e.g. colour, font, size to be specified for certain elements of a hypertext document. Style information can be included in-line in the HTML file or in a separate CSS file (which can then be easily shared by multiple HTML files). Multiple levels of CSS can be used to allow selective overriding of styles.
