I was visiting a photography blog the other day and was having a lot of trouble reading it. All of the links we blending into the background. Being color blind I was wondering if it was just me and that was the way it was intended. When I asked the site owner about it he said it was a problem with IE and didn't know how to fix it.
Of course being the geek that I am I couldn't leave it at that. I pulled down the source (evidently a WordPress template) and his style sheets. Everything looked fine, it just wasn't working as intended.
I did a test and verified that it was working fine in Firefox. I fiddled around for a while and put "important!" in a few places and what do you know. It works, for the most part.
