Background Image Always Align To Top

I am working on a wordpress menus. my sub menu image is little bend to angle. I have attached the image for better understandings. My problem is concerned with sub menu. backgroun

Solution 1:

Remove the height specified for submenuMenu. Add height as auto

.submenuMenu{
    width: 649px;
    height: auto;
    float: left;
    margin: 39px003px;
    padding: 11px000!important;
    background: url(../img/bg_submenu.png) left bottom no-repeat, #f4bfd5;
}

Make sure that your image is of 25-30px height and for the remaining space you can give background-color.
