background image for the Page Menu Bar

Hi

I'm using Atahualpa 3.4.9 with wordpresmu.

I was in the option «Varios Content items», then «Add html/css inserts» and finally «Css inserts».
I've added this code :

div#menu1 {
background: url(/xxxx.com/wp-content/themes/atahualpa/images/menu_image.jpg) ;
}

It works partially, The background color hover is ok.
The menu page items have the color background that i've sent in «Page Menu Bar» / «Background color». How can i force to take my image as background for the page menu bar?


Thanks.
