Cascading Style Sheets:
Selectors, Units, Atrributes and Values
The following displays the selectors, units, and attributes supported by CSS and the two major browsers. Additional information about CSS and browser support for current CSS standards can be found at the following Web sites:

Since the World Wide Web changes constantly, you should test this
information against current browsers.
