Acid2 browser test.
Want to see what browser is standard-compliant and what’s not so, and what’s totally not?
Go do the Acid2 Browser Test in your web browsers and soon you will know. Last I know only Safari was fixed to render that the right way as stated in the reference rendering.
Firefox didn’t really did a good job as of time of posting. And MSIE6 is a total disappointment, but there wasn’t anything short of that within my prediction! ;)
