Well, you really shouldn't be using tables to layout links like that. But it looks like you might be dealing with code given to you that can't be directly edited...
This should do it.
Code:
.pricingcell:hover {
background: red;
}
The .pricingcell class is what gives the div its color, so that's what you're changing. Ideally, though, there would be an
<li> with a
<a href="#"> inside it that you'd control with
Code:
.the-class-name a:hover{
/* stuff */
}
