CSS Generated Content

Author: Dynamic Drive

CSS2 supports the insertion of generated content, which is content that's specified using your style sheet and applied dynamically to the page according to your CSS definition. This is very useful for further decorating an element with rich content that should not be part of the page's actual markup. CSS Generated Content is accomplished using the ":before" and ":after" pseudo-classes, which denotes whether the content should be added before or after the element in question. You can insert regular "string" content or an embedded object (ie: an image). CSS2's Generated Content is supported in Mozilla/Firefox and Opera 7+, and IE7+
