CSS Expands Palette with Variables
CSS is a stylesheet language, one that defines for a browser how a Web page, Web presentation or some other form of electronic content should be formatted. CSS offers a set of keywords to specify stylistic elements in a page layout, such as the font and spacing of text, and the color of the background. CSS can be embedded in the HTML page itself, either in the header or in the body. Or CSS code can be a separate file on the server, which is then referenced by the page. Read the full story here.
