How to check your CSS sites?
 

What is the best and easiest way to check your CSS sites in varoius browsers and versions on one PC?

Your best bet is to literally download the various browsers and try them. Simulators and such are only partially accurate as they are are just some programmer's interpretation of what the browser would show you.

If you want to be certain... do it yourself.

I agree, I check my sites in IE and FF - don't have time for more ;)

And make sure your site passes validation or at least get it as close as possible.
