Book or website which lists browser compatibility for all CSS elements?

Question

I am looking for a resource (book or website) which lists all the CSS elemenets' compatibility with the major browsers. It has to include information for IE8 & FireFox3 (Chrome not too important). The ones I have found do not mention IE8 so I need one that's up to date to include IE6, IE7 and IE8.

For example, if I want to use 'border-spacing', I want to know which browser does not support it, if any.

In particular, for your question on border_spacing: http://www.quirksmode.org/css/tables.html
