So I've been looking at stylesheet.css and web developer tools in FF.

Correct me if I'm wrong, but I think it is the .rowEven line 115. I've even removed background-color:#fff; from the css file and it still manages to have one there when I'm back at the page: background-color: #FFF;
If I untick the box it in web developer, the white background goes and it works perfectly, I'm not sure what keeps making the background come back even though I've removed the background-color:#fff; code completely, hope I'm making sense.
