Simple CSS tabs - need to break border on active tab

I want to create a very simple tab style that looks like this:

_____ _____ _____
_|_____|_| |_|_____|______________


So basically there is a horizontal border on the bounding box that breaks for the active tab. I'm using a basic list, with the following CSS, but the outer border always appears over the individual tabs. I've tried various positioning and z-index as well to no avail.

ul.tabHolder {
overflow: hidden;
clear: both;
margin: 1em 0;
padding: 0;
border-bottom: 1px solid #666;
}
ul.tabHolder li {
list-style: none;
float: left;
margin: 0 3px -1px; /* -1 margin to move tab down 1px */
padding: 3px 8px;
background-color: #444;
border: 1px solid #666;
font-size: 15px;
}
ul.tabHolder li.active {
background-color: #944;
border-bottom: 1px solid #944;
}

ABOUT THE CODE Some lists within the Listamatic site had to be modified so that they could work on Listamatic's simple list model. When in doubt, use the external resource first, or at least compare both models to see which one suits your needs.
