The WebKit development team has just passed another huge milestone. The WebKit browser engine used in Apple’s Safari and Google’s Chrome now fully passes the Acid3 test.
The Acid3 test checks how well browsers comply with the latest standards, in particular JavaScript and the Document Object Model (DOM).
Maciej Stachowiak of the WebKit team attributes this feat to “recent speedups in JavaScript, DOM and rendering.”
Unfortunately, it will be a few months before we see this in Safari and Chrome, but while you wait you can download a nightly build of WebKit and test this for yourself.
