Acid3

Acid3 is test for Web-browsers. I am not joking when I say it doesn’t involve acids!!!!!!! Acid3 is a test page from the Web Standards Project that checks how well a web browser follows certain selected elements from web standards. Acid3 especially relating to the Document Object Model (DOM) and JavaScript.

When the browser passes a subtest, the Acid3 test page displays a gradually increasing percentage counter with colored rectangles in the background. In addition to these the browser also has to render the page exactly as the reference page is rendered in the same browser.

Acid3 was released on 3 March 2008. The main developer was Ian Hickson.

The details represented below is taken from the wiki page of Acid3

The main part of Acid3 is written in ECMAScript (JavaScript) and consists of 100 subtests in six groups called “buckets”, including four special subtests.

* 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[4]
* Bucket 4: Behavior of HTML tables and forms when manipulated by script and DOM2 HTML
* Bucket 5: Tests from the Acid3 Competition (SVG,[5] HTML, SMIL, Unicode, …)
* Bucket 6: ECMAScript

The compliance criteria require that the test is run with a browser’s default settings. The final rendering must have a 100/100 score and must be pixel-identical with the reference rendering.

As the test is run, rectangles are added to the rendered image; the color of the rectangles is decided by the number of subtests passed in the bucket. If all subtests fail in a particular bucket, its associated rendered rectangle will be invisible. If some subtests are cleared the color will change in four steps:

* 1–5 subtests passed: Black rectangle.
* 6–10 subtests passed: Grey rectangle.
* 11–15 subtests passed: Silver rectangle.
* All 16 subtests passed: Colored rectangle (red, orange, yellow, lime, blue, purple—for each of the six rectangles, respectively)

Now that the working of Acid3 test known lets see the results of the test.
Clicking on the letter A display the test stats.

Let us start with the web browser that passed the test.

Firstly my beloved browser Opera.

Browsers those failed the test

Surprisingly FireFox 3.6
The number isn’t bad, but it still has some distance to travel.

Worst result
Not surprising it’s IE8 with a score of 20. IE 7 was even worst it had a score of 12. I could not check IE 9 since it doesn’t work on Windows XP.

The test result.

IE 8 - the worst web browser.

COMING SOON ACID2 AND ACID1
