.headerbar {
background-color: transparent;
background-image: url('LINK IMAGINE');
height: 170px;
background-position: top;
background-repeat: no-repeat;
}

body {
background-color: transparent;
background-Image: url('LINK IMAGINE');
background-repeat: no-repeat;
background-attachment: fixed;
background-position:center;
}


Also tried this one, and it changed my forum backgorund color to white....

#search-box #keywords {
width: 95px;
background-color: #ffffff;
}

input.search {
background-image: url('http://sonsofanarchyforever.com/images/bg_search.png');
background-repeat: no-repeat;
background-position: left 1px;
padding-left: 17px;
}
