Aljan,
I recently was working with a similar problem, and the solution I came up with was hardly elegant, basically I added:
/*Adds the background image to the menu container area*/
.MainMenu_MenuContainer {
background-image: url(menu_background.gif);
}
/*Helps place text, adjust per your needs*/
.MainMenu_MenuItem {
padding-top: 13px;
padding-bottom: 13px;
}
/* Don't forget to set padding in your selected item, so the menu doesn't spaz out */
.MainMenu_MenuItemSel {
padding-top: 13px;
padding-bottom: 13px;
}
/* Set the Submenu background color info */
.MainMenu_SubMenu {
background-color: #003769;
}
Hope that helps some, good luck.
