CSS
An acronym for Cascading Style Sheet, CSS is a standard developed for determining the appearance of text and other elements on a web page. A single CSS file can be created that specifies how elements should appear; for instance, body text in a 12 point Arial font. This style can then be applied to all the pages on a site. To change the font across the entire site, only the CSS file has to be modified.
