Basically, the best thing I can say is that it works and is positioned the way it should be, in Firefox however it isn't in internet explorer. Only code I left out was the nav's hover effects.


css
Code:
html {
    min-width:999px;
}

body {
    color: #2b2b2b;
    font-family: arial;
    min-width:999px;
    margin: 0px;
    padding: 0px;
    background: #f1f1f1;
}

img {
    border: 0px;
}

ul, li {
list-style-type: none;
display: inline;
}

a, a:visited {
text-decoration: none;
color: #444;
}
a:hover {
text-decoration: underline;
color: #000;
}
a:focus, a:hover, a:active { outline:none }

#container {
background-image: url(http://berryequipment.net/berry3/images/layout/headerbg.jpg);
background-repeat: repeat-x;
text-align: center;
    width: 100%;
}

#main_container {
    position: relative;
    text-align: center;
    margin-left: auto;
    margin-right: auto;
    width: 950px;
}

#header {
text-align: left;
width: 950px;
height: 118px;
background-image: url(http://berryequipment.net/berry3/images/layout/topbg.jpg);
}

#logo {
float: left;
width: 285px;
height: 106px;
background-image: url(http://berryequipment.net/berry3/images/layout/logo.jpg);
}

#main_nav {
padding-bottom: 10px;
position: absolute; bottom: 0px; left: 321px;
text-transform:uppercase;
font-family: helvetica, arial;
font-size: 12px;
text-align: left;
color: #FFF;
}
index
Code:
<?php
    session_start();
    header("Cache-control: private");
