Ok, could someone help me make a footer with this layout?

body
{
background: #003300;
font: 10px Verdana, Arial, Helvetica, sans, sans serif;
margin-top: 0;
margin-bottom: 0;
margin-left: 0;
margin-right: 0;
padding-left: 0;
padding-right: 0;
}

#header {
margin: 20px;
padding: 10px;
height: 100px;
}
#nav {
position: absolute;
left: 15px;
top: 160px;
width: 200px;
}
#content {
top: 0;
margin-left: 230px;
margin-right: 230px;
}
#right {
position: absolute;
right: 15px;
top: 160px;
width: 200px;
}
