Set menu background color to fill entire window's width

Hello,

I am using Block/BlockBlue2 menu, and I would like to know how to fill that blank space where the menu is not enough large to take that space. I don’t find the menu css property to set that.

Thank you in advace.

PS: Menu Line property did not solve the problem.

I ended doing this ugly thing in onLoad() event :o


?>
<style>
    #idDivMenu{
        background: #3D3E3F !important;
    }
</style>
