Less crazy than the Acid Tests is www.html5test.com
Here’s what I get from a few random browsers I have lying around the place:
Firefox 3.5.9 scores 100 out of 160.
Chrome 4.1 scores 118 out of 160.
IE6? 11 out of 160.
IE8? Surprisingly, only 19 out of 160.
The browser on my Nokia N95 phone doesn’t load the page properly; it just says “Working…” and 0 out of 4 (eg it stalls on the first round of tests).
Interestingly, I also tried IE6 with the Google Chrome Frame in it; it scored 137 out of 160, better than Chrome itself. Weird.
Obviously all the browser authors have a way to go to support this if it’s going to be the bold new standard on the web.
