The Acid 2 test has, for a few years now, been the de facto test for your browser’s CSS capabilities. The Acid test, fewer people know, is not really about conforming to standards – passing it does not make your browser standards compliant or complete, so it’s best to understand that all it really means is that it properly handles the elements tested as well as certain errors properly. Sometime in 2005, Safari passed Acid 2, becoming the first mainline browser so earn that honor. A few years later, the current or development versions of all major browsers – including Firefox 3, IE8, Opera 9.5 – all pass the Acid 2 test.
Enter Acid 3. Acid 3 measure even more goodness, including these six “buckets”:
Bucket 1: DOM Traversal, DOM Range, HTTP
Bucket 2: DOM2 Core and DOM2 Events
Bucket 3: DOM2 Views, DOM2 Style, CSS 3 selectors and Media Queries
Bucket 4: Behavior of HTML tables and forms when manipulated by script and DOM2 HTML
Bucket 5: Tests from the Acid3 Competition (SVG, HTML, SMIL, Unicode…)
Bucket 6: ECMAScript
Using recent browsers, everything fails pretty spectacularly. My Opera 9.26 install gets a 42/100. Safari (including iPhone) does 39/100. IE7 does 12/100, Firefox 2 does the most respectable with 52/100. Even IE8 only does 17/100 while Firefox 3 tops out at 59/100 and Opera 9.5 at 60/100. The current generation, even the next generation of major browsers are still far from coming close to rendering Acid 3 with any accuracy.
I have been playing, now and again, with Webkit nightlies, since Webkit is actually a really neat engine, and guess what it kicks out? This:
