Dhtmlxlauout and dhtmlxTabbar

I have the following code in my html file. An object is attached to layout at the bottom and the bottom contents has a Tabbar. This code works fine bu the Tabbar shows up with a background color simliar to Layout skin. How do I remove the background color of the tab

If you mean zone with where tab-caption placed - its background defined as
dhtmlxlayout_dhx_blue.css
table.dhtmlxLayoutPolyContainer_dhx_blue .dhx_tablist_zone {
background-color:#D3E2E5;
}


The content part of tabbar must not have any background-color

If you mean some other coloring - please provide a screenshoot and point to incorrectly colored area.
