Browser support for CSS properties

This table tells you which browser supports which bits of the CSS specification. It is not complete but it is the best I can do. A 4 for Yes, a 8 for No, and an M for maybe (it might work, it might not work or it sort-of works). I try to keep this up-to-date but things change. There are later versions of Navigator that I haven’t included.
