WebKit becomes first browser engine to fully pass Acid3 test

Maciej Stachowiak of the WebKit team has announced that the browser engine behind Safari is the first to fully pass the Acid3 test, including the test's condition of smooth animation rendering.



Acid3 is a test page from the Web Standards Project that scores how well a rendering engine follows defined web standards, particularly DOM and JavaScript. The test provided a metric for standards compliance that has resulted in rapid advancement among various rendering engines as each works to earn the top score.



In March, both Safari's WebKit and Opera's Presto announced earning a 100% score in developer builds of their browser. In addition to the numbered score, the test also requires the browser render a test page with pixel perfect accuracy using its default settings and that it render a smooth test animation.



Today, the development build of WebKit passed that last hurdle, which Stachowiak reported was due to "recent speedups in JavaScript, DOM and rendering."



Actual shipping builds of the world's various web browsers haven't yet reached 100%. According to figures in Wikipedia, the latest Safari 3.1.2 has a score of 75, while Firefox 3.0.2 has reached 71, Opera 9.52 has reached 84, and Internet Explorer 7 is at 14.



In internal builds, the Safari 4.0 Developer Preview has reached 100, while the latest build of Firefox Gecko engine has reached 87, the latest build of Opera earns 99, Google's new Chrome beta has reached 79, and the Internet Explorer 8 Beta 2 scores 21.



Among mobile browsers, the shipping version of Safari in iPhone 2.1 reaches 74, while the Netfront browser hits 11, Opera Mobile reaches 2, Opera Mini has hit 79. Pocket Internet Explorer can't run the test due to a lack of JavaScript support.

    Internet Explorer 8 Beta 2 scores 21.

    Pocket Internet Explorer can't run the test due to a lack of JavaScript support.

    shows how good Microsoft really is.

    Then why does my iPhone crash everytime I use Safari to access a Java intensive website?



    I thought Steve said Java was a dead platform? Seems to be putting a lot of effort into a dead platmorm.

    Now how about making up with Adobe and giving us Flash on the iPhone.



    Google is catching up!

    Wrong!



    Actually, Safari hit 100/100 just *before* the Opera event you quote.



    This latest milestone is 100/100 with the smooth animation on top. Of course if you read the article and knew anything about the race to beat Acid 3, you might know that.

    100/100 is a perfect score, but just getting a perfect score does not pass the test. You have to get a perfect score and do it smoothly. This was what the test creators said, otherwise you don't pass.

    For what it worths, I downloaded Safari beta 4 (build 5526.11.2) on 12 aug 2008, and it passes Acid3 with a perfect score and smooth animation...

    Cheers,

    Who cares with who gets 100 in Acid3 first? The point is, WebKit and Presto is fully standard compliant.



    Oh yea, erm...when people mention the major browsers, people only mention, IE, Firefox and Safari. Its a lil bit sad that eventhough Opera Presto passed Acid3 test with flying colors, no one really talk about it.

    It's a test of the user experience. Browsers have a lot of work to do with images, animations and Javascript, the Acid test demonstrates how well they can do that work.

    I agree, I used to love Opera and still do. They just don't seem to do enough to publicise it. It's a shame really, I only stopped using it because of problems using some secure sites like PayPal, otherwise I would replace Firefox with it.

    ...If the folks in Redmond actually get on the web to see their browser dead last, but I think that statistic illustrates the very problem. They can't stand to sit through a image-intensive / javascript session either.

    Actually, which Safari? Only on mac, right? I re-read the article and never said if it was 100% on mac or on PC or both? I assumed it's for mac only?

    ACID3 tests a lot of SVG. People often see Acid as 'the thing that makes a browser good/perfect' but in fact it just tests a small part of mostly rendering aspects of the browser.



    ....Which doesnt mean it's not a good thing. I'm glad there are tests like these.

    Here's a comparison of browsers and Acid3.

    I love Opera, and used it back in my PC days, but they really need to do something about that interface.
