Look for 923 Style in this part:
quote:
button[class="TabButton"]
{
foreground:rgb(152,151,139);
Accessible:true;
AccRole:43;
tooltip:true;
animation:rectanglev|fast|log;
alpha:192;
padding:rect(1,1,0,1);
}
button[class="TabButton"][enabled=false]
{
foreground:rgb(128,128,128);
alpha:178;
}
button[class="TabButton"][selected]
{
alpha:255;
background:rcbkd(59150);
padding:rect(0,0,0,0);
BorderColor:rcclr(20020); /* Colorized. I=207 */
BorderThickness:rect(1,1,1,1);
}
button[class="TabButton"][mousewithin][selected=false]
{
alpha:255;
background:rcbkd(59150);
}
button[class="TabButton"][keywithin][selected=false]
{
alpha:255;
background:rcbkd(59150);
}
You can use the background yo want for this element, here you can see how to use an image for that purpose, also you can use RGB colors of course, try playing with bordercolor and padding to get the result you want, i hope this helps, i do my best
