Thank a LOT! It works. I tried to add the spearator line between the title and the content like this:
.contentbottom .module, .contentbottom .module_menu {
background: none repeat scroll 0 0 #EEEEEE;
border: 1px solid #D9D9D9;
border-radius: 5px 5px 5px 5px;
}
.contentbottom .module_padding {
padding: 10px;
}
.contentbottom h3 .module h3 {
background: url("../images/sep1.png") repeat-x scroll 50% 100% transparent !important;
padding-bottom:10px !important;
}
But even, when the !important is declared, these rules are overriden :S
