I stumbled upon CSS Contents and Browser Compatibility today via etc..  It has a side-by-side comparison of web browser support of CSS features broken down by selectors, pseudo-classes, declarations and experimental declarations.  The web browsers compared are IE 5.5, IE 6, IE 7, Firefox 2.0, Safari 3.0 (Windows), Opera 9.5 Beta, iCab 3.0 and Konqueror 3.5.7.

It’s not surprising to see that as you scroll down the page semi-quickly, a majority of the red shows up in the Internet Explorer and iCab columns.  Beyond that, it looks like Firefox and Opera deserve some props for having only one red box each for the features in the first three categories.  Konqueror’s not far behind with about two-and-a-half, depending on how you count the “Incorrect” implementation for background-attachment.

What stands out, though, is the support for experimental features.  Konqueror leads in that category with support for three features, Safari’s next with support for two-and-a-half, and then Firefox and Opera with two each.  The other browsers fail to even register in this area (again, not surprisingly).

See anything else interesting in the stats?  Post a comment.
