Webkit gets a perfect 100 on Acid3

In the rather rarefied atmosphere of web standards compliance, the Acid3 suite of browser tests is like a pro wrestler's chair to the back of the head: if you can take it and keep standing, that's very impressive. The Acid3 suite, first released at the beginning of this month, pushes browsers to the very edges of their rendering, SVG, CSS and DOM scripting capabilities -- all necessary for a consistent and interoperable Web 2.0 experience.

As with the earlier Acid2 test, there's been a bit of a horserace among browser development teams to be the first to the finish line with Acid3, including the WebKit squad responsible for Safari's underlying engine; Acid3 dev Ian Hickson gives major props to Apple and the WebKit devs on his blog, including efforts to clear bugs in the test suite itself (he had to work quite hard to find standards compliance issues in WebKit). On Wednesday evening, both the Opera and WebKit teams declared a 100% score -- not a full pass, as there are minor issues to clean up, but nevertheless the test looks like it should. With the Mac nightly build of WebKit available for download, you too can feel the power of this fully operational web standards battle station.

[A quick clarification: While both Opera and WebKit have claimed 100% on Acid3, only one of the browsers -- WebKit -- has a publicly downloadable version right now that can make that score. Opera's build won't be released for another week or so.]

Thanks Adam

The acid tests are indications of how well a browser engine follows the specs for the various standards. Making bad tag soup HTML render exactly like IE is something very different.

Do not forget "test" #101 !!! ;) The animation must be smooth.

I am sure that Opera will score 100/100 when they get their Opera 9.5 Beta out...

Thus, let's wait and see which one has smoother animation - Opera or WebKit. Only then we will have a true winner!

"feel the power of this fully operational web standards battle station."

LOL, I almost snarfed!

Honestly, the best aspect of TUAW is the sense of humor of its contributors. Makes it a pleasure to read. Thanks, Mike. You made my day! :)

Well, my freshly downloaded Webkit gives me 99/100 and not the perfect 100... :(

I love Opera, despite the fact that I never use it, and rarely even test my sites in it. My process for making web sites is as follows:

1. Start with Safari and have a perfectly working site.
2. Fix things for Firefox's bugs.
3. Pull my hair out wondering why IE6 and IE7 suck so hard.
4. Open Opera and see what I was expecting.

Did Safari for Windows pass as well or just Mac?
I saw tons of rendering issues in the Windows version...Especially with Bank of America's site.

Yes, Safari for Windows passes ACID3 as well. BUT, most existing sites are designed for IE, so rendering issues you may see are likely related to the site providing non-standard HTML specifically for IE.

Safari has not passed Acid3, on either platform. WebKit's latest nightly build passes. Safari != WebKit. :-)

Actually the new version of Safari has a User Agent list (go to Preferences/Advanced and turn on "Show Develop menu in menu bar" and it is there.

It may be possible to view the site properly by identifying itself as IE or FF.

That user agent setting doesn't seem to work for some sites. Back when Yahoo Mail's "advanced" inbox didn't support Safari, no matter what browser I selected in the user agent menu, I'd get the "unsupported browser" message.

Yeah, so why won't Safari 3.1 work with my bank's Web billpay?

More the point, why won't Apple provide an easy way to downgrade Safari (Safari runs on webkit) for those of us who can't really use it?

Either they don't stick to standards or they're actively blocking WebKit browsers from working.

MySpace, for example, stopped Safari users from using the advanced editor for a while even though it would have technically worked back when Safari 3 first came out.

I have a video of webkit passing acid3 here:

Part of the test is the "smoothness" of the animation as well.
