<!-- CSS 2.1 Reference

Property Name: content

This property is not supported by Internet Explorer, up to and including version 7. Using alternative methods is recommended instead for content that is intended for browsers, considering the current support status of this property. Defines "content" which is generated or retrieved when the document is loaded, and appended before or after the selector. Uses the pseudo-elements :before and :after. This property will either render additional content around the selector, or load it from a remote location in the case of a URI entry. For example, if you were to add p:before {content:"-";} to a document, a dash character ( - ) would appear before every opening <P> tag, while the closing </P> tag will not be effected.
