css - What's the best way to test cross-browser compatibility?

Question

Since the portable versions of Internet Explorer are no longer supported (and never fully worked) I'm trying to find a way to test sites in a number of different browsers.

The lag on something like browsershots.org is far too high to be practical, plus you can't test functionality.

I'm looking at using VMWare images of Windows XP with different versions of browsers installed, but it seems like a right pain.

Is there any other method of testing CSS compatibility on browsers?

Answer 1

If running Windows, for Internet Explorer try IETester or IE Collection. They contain all versions of Internet Explorer.
