position: absolute on Tabbed Menu Causing Overflow Problems

Question

When I set position: absolute in my tabbed menu, I get overflow problems.

here's the link to see the issue (click on tab #one)

CSS

I've tried various jQuery and JavaScript tabbed menus but they conflict with the java controlling the background image sizer (I've inherited the site trying to fix someone else's work)

this is the css:

#tabs {margin: 10px auto;min-height: 250px; width: 560px;position: relative}
#tabs li div p {text-align: left}
#tabs a {color: #000;text-decoration: none;outline: none;}
#tabs ul {float: left;margin: 0;padding: 0; position: relative}
#tabs li {float: left;list-style-type: none;}
#tabs li a {
background: -webkit-gradient(linear, left top, left bottom, from(#bdccaa), to(#869968));
background: -moz-linear-gradient(center top , #bdccaa, #869968 18px) repeat scroll 0 0 transparent;
background: -o-linear-gradient(center top , #bdccaa, #869968 18px) repeat scroll 0 0 transparent;
