About a month back, Håkon Lie announced the planned creation of a browser technology test page named Acid2. The Web Standards Project agreed to sponsor and host the effort. Now the Acid2 test has been launched, although it hasn’t yet been officially announced.
It’s quite an ingenious work of art actually. It consists of a complex HTML page which makes use of a whole number of advanced CSS2 features. If rendered correctly, the various divs and spans and what-nots will make up a happy yellow face.
This test page makes me realize that even though Opera and Firefox are pretty good, they still have some way to go before they fully implement the available and useful standards. Here are screenshots showing how three common browsers cope with the test:
Here are screenshots of some old and some yet-to-be-released browsers: (Comparing Netscape 6.1 and a recent Firefox nightly build shows how far the Gecko layout engine has come since August 2001.)
Hopefully the Acid2 will inspire all the browser makers to further improve their standards compatibility. He who lives shall see.
Update: Reduced the size of the screenshots a bit.
