CSS: Multiple Hovers

Hi,
How can I have multiple hover statements so that different classes can been a different colour when hovered over?
At the moment I have two sets of links, with two different classes in my styles sheet.

A:Hover { text-decoration: none }
.main_links { color: whatever }
.sub_links { color: whatever }

So, all my links have no underline, but what if I want one set of links with underlines and one without?

Is there anyway to do this?

TIA,

Jord

I think this works:

A.main_links:Hover { color: whatever; text-decoration: underline; }
A.sub_links:Hover { color: whatever; text-decoration: underline;}

How do I add that to my linke, like <A CLASS="main_links"></A> ?

Yep ... that's exactly what you'd do ... except one of your text-decoration values would be "none".
