CSS Specs

Where do I go to find out which CSS things were introduced in what level? Someone sent me the URL but I accidentally deleted the message. 
The reason I'm asking is because Internet Explorer 6 supports font: status-bar. I couldn't believe that IE supported some bit of CSS3 and am trying to make sure it is in fact CSS3. Can someone tell me if Safari 1.2 supports font: status-bar? The Test page is http://www.geocities.com/seanmhall2003/css3/fonts.html . It probably does but I want to make sure. 
I've added "test Page" links to everything in the compatibility tables, except List Styles (I'll get to it): http://www.geocities.com/seanmhall2003/css3/compat.html 
Cheers and happy browsing,
