While working on the 2011 version of AMeijer.NL I discovered a bug involving text.
As you can see in the image, the lower text looks a bit disturbed. Note that all other CSS properties are exactly the same! The only different property is position:relative!
The bug only occurred on webkit browsers (Chrome and Safari) and did not occur in the latest version of Firefox. I don't know where the webkit working group is aware of this bug, but let's hope they'll fix it soon!
