CSS z-index issue top menu background - html

Question

I try to display a cloud as background on my menu, it actually gets displayed (just a little part) but it's hidden by the menu background. I had applied z-index on both items but it's not working.
The CSS code I'm using is :
/*** ESSENTIAL STYLES ***/
.sf-contener {
clear: both;
}
.sf-right {
margin-right: 14px;
float: right;
width: 7px;
}
.sf-menu, .sf-menu * {
margin: 0;
padding: 0px 0px 0px 0px;
list-style: none;
}
.sf-menu {
margin: 10px 0;
padding:0px 0px 0px 0px;
width:980px;/* 980 */
background: #383838;
}
.sf-menu ul {
position: absolute;
top: -999em;
width: 10em; /* left offset of submenus need to match (see below) */
}
.sf-menu ul li {
width: 100%;
}
.sf-menu li:hover {
visibility: inherit; /* fixes IE7 'sticky bug' */
}
.sf-menu li {
float: left;
position: relative;
top: 0;
/*border-right: 1px solid #777;*/
}
.sf-menu a {
display: block;
position: relative;
color:#fff;
}
.sf-menu li:hover ul,
.sf-menu li.sfHover ul {
left: 0;
/*padding: 0px 0px 0px 0px;
margin: 0px 0px 0px 0px;*/
top: 35px; /* match top ul list item height */
z-index: 99;
width:auto;
}
ul.sf-menu li:hover li ul,
ul.sf-menu li.sfHover li ul {
top: -999em;
}
ul.sf-menu li li:hover ul,
ul.sf-menu li li.sfHover ul {
left: 200px; /* match ul width */
top: 0;
}
ul.sf-menu li li:hover li ul,
ul.sf-menu li li.sfHover li ul {

}
ul.sf-menu li li li:hover ul,
ul.sf-menu li li li.sfHover ul {

Any ideas?
Thanks for your help

Answer 1

If that cloud thingy should be visible completely, the you could:
add a padding-top: height-of-cloud-background(I think its 20px or smthing like that) to the <a> tag that has this background
and pull the <a> tab back up by using a margin-top: negative-height-of-cloud-background
So basically as far as I see it in your menu:
.sf-menu a.sf-with-ul{
/*extra code stuff*/
padding-top: 20px;
margin-top: -20px;
}
Then again you could use a :pseudo class on this specific tag is it fits better.
