Centering problem in firefox. I think I'm losing my mind! [:@] I don't have that much code, but I can't seem to see what I did to cause this centering problem.
Webpage
<body>
<div id="container">
<div id="header"><img src="images/logo.gif" alt="Lawson Design Studio" width="450" height="150" /></div>
<div id="top">
</div>
<div id="main">
</div>
<div id="bottom"></div>
</div>
</body>
CSS
body {margin: 0 auto; padding: 0; text-align: center; line-height: 1.5em; color: #000; background:#4b4a49 url('images/bg.jpg') repeat-x;}
#container {margin: 0 auto; text-align: center; width: 760px; height: 650px; }
#header {width: 450px; height: 150px; padding: 0; margin-top: 40px;}
#top {width: 450px; height: 50px; margin-top: 10px; padding: 0; background:url(images/content_top.gif) no-repeat;}
#main {width: 450px; height: 300px; padding: 0; background:url(images/main.gif) repeat-y;}
#bottom {width: 450px; height: 145px; padding: 0; background:url(images/content_bottom.gif) no-repeat; }
