Hi, basicaly I have the following HTML/CSS Layout
HTML:
<div id="container">
    <div id="main">
        <h1>TEST</h1>
    </div> 
</div>
CSS:
#cont {
  width: 100%;
  background: #ddd;
}
#main {
  width: 900px;
  background: #fff;
  margin-left: auto;
  margin-right: auto;
}
This works fine in FF, safari, Chrome and Opera but IE8 still aligns the "main" div to the left.
Does anyone know what the problem might be? Thanks in advance.
