I can’t find it anywhere. I do not know where I have to look.
Edit: I find it in stylesheet.css. Is that it?
header{
width: 100%;
display: block;
position: fixed;
z-index: 2000; <<<Is this the value? If yes, when I change from 2000 to 1000 overlay is not working.
background-image: url(img/menu_shadow.png);
background-repeat: repeat-x;
background-position: 0px bottom;
padding: 0px 0px 3px 0px;
