I'm a newbie and would appreciate some help. I've set my h1 with the following css

#mainbody h1 {
color: #990000; /*dark faded red*/ background-color: #FFFFFF; /*white*/
font-weight: bold; font-size: 120%;
text-decoration: none;
border-bottom: 1px solid #990000; /*dark faded red*/
padding-bottom: 1px;
margin-bottom: 0.8em;

but in

I'd like h1 to have no line on the bottom.

I'm just not sure how to do it, except not calling it h1. Is there a way?
