Opera Mobile becomes the first mobile browser to pass the Acid2 test

May 24, 2006

Opera Mobile for the Series 60 (S60) mobile phones has passed the Acid2 test in its internal builds (See screenshot below), according to Gerdur Jonsdottir, an Opera developer working on the browser.

This makes it the very first mobile browser to pass the Acid2 test.

“This is a version still in its early stages but this is definitely promising”, says Gerdur.

The Web Standards Project (WaSP) released the Acid2 test, a test page for web browsers. It has been written to help browser vendors make sure their products correctly support features that are part of web standards.

Acid2 tests for features that are part of existing standards but haven’t been supported by major browsers. Acid2 is a complex web page. Though not all web standards are tested, it uses features that are not in common use yet, because of lack of support, and it crams many tests into one page.

Opera 9, Konqueror, and Apple’s Safari browser have passed the Acid2 test on their desktop browsers.

    Excellent!

    But how different is Opera Mobile from Opera Desktop? I thought they used the same rendering engine. Is this just a matter of merging the changes from the desktop version into the mobile version?

    Kelson, I don’t think it would make sense to say that the rendering is the same for desktop and mobile browsers.

    The core, which I believe is the parser and DOM structure, is the same, the rendering, however, is different — since Opera’s mobile browsers use the ERA architecture, which eliminates the horizontal scrollbar by reformatting the page. So the formatting (redering) is different.

    Perhaps one of the Opera developers can shed more light on this.

    I always thought that we don’t need .mobi domain. I’d rather see Ireland give its TLD to some primitive browser 🙂

    I just tried this, and for me, Opera 9 beta 2 passed the Acid2 test.

    I’ve put up screenshots on my website.

    Daniel,

    your wrong about the rendering engine being different. Its exactly the same as on desktop. The ERA feature your refer to also exists in the desktop browser.
