I Need Help Fixing Full-Width Header

[Debra]

first the formatting should look like this

background: #85ACAC url(images/header.png) no-repeat;

then

headerleft should look like

.headerleft {
width: 960px;
float: left;
font-size: 14px;
margin: 0px;
padding: 0px;
}

If you want to stretch the image to fit add this
.headerleft a img {
border: none;
margin: 0px;
padding: 0px;
width:960px;
}

header right should be 0px

.headerright {
width: 0px;
float: right;
margin: 0px;
padding: 20px 0px 0px 0px;
}
