The CSS3 Test

Now there's a nice surprise, Nightly (Firefox-alpha build) actually scores one percent higher than Chrome Canary. I do hope Mozilla catches up in other areas, there needs to be more than one large non-Webkit browser out there to push the web forward.

Very nice. One quibble - The warning in the top right is a tiny bit ambiguous, it would read better as:<p>"Caution: This test checks which CSS3 features the browser recognizes, <i>not</i> whether they are implemented correctly."

I am actually a bit surprised the latest Opera didn't score better than 56%. Oh well, I guess I'd complain about the speed if everything was implemented.

Here's Lea Verou's (the creator) blog post about this:<p><a href="http://lea.verou.me/2012/02/exactly-how-much-css3-does-your-browser-support/" rel="nofollow">http://lea.verou.me/2012/02/exactly-how-much-css3-does-your-...</a>

What is it? I loaded it up in Internet Explorer and the page wouldn't render.

Does this check vendor prefixed (-webkit,-moz,...) "features" too?

Hmm, Firefox 9.0.1 scored 0% (with Ghostery installed); Forefox 10 scored 60%. They both still score 95% in the Acid3 test. I'm not uninstalling Ghostery, whatever the score.

I hope they are recording the user agents and versions. That data would be very valuable.

I'm curious to see how IE10 preview scores in this test, anyone have it handy?

Anyone tried IE9 ? I wonder how much it scores.

Chrome 18.0.1025.1 dev scores 63%
