I was looking for a way to have a hover effect over a group of text possible containing an image. I came across this example which looks like a good explanation.
This example is from 2006 - Is this still a good technique to use, are there now better or more relevant methods.
You can also use Whatever:hover so you can make all elements hoverable in IE, not just <a> tags
As mentioned if you want to support IE6 you need to make everything happen on and insider the anchor like this.
The problem is that it is not very semantic and we ran a css quiz that showed another way to do it and allow normal html elements to be used.
Or with a js helper for IE6.
