separator line to strech 100%

[peerapat]

Hi,
    I'm using 2009 Q1 version to create horizontal menu. And I have removed vertical line and left space by using

<style type="text/css">

.RadMenu_Vista .rmGroup

{

border: 1px solid #979797 !important;

background: #f0f0f0 !important;

}   .RadMenu_Vista .rmGroup .rmLink {           padding-left: 0px !important;         }               .RadMenu_Vista .rmGroup .rmLink .rmText {           padding-left: 5px !important;        }

</style>

   The separate menu item is aligned right with some space on left. How do I eliminate this space and make separator stretch 100% on the menu.
Thanks
