Hopefully you are also relying on an external sheet to help you maintain the consistency of the layout as well.

Here is another example
body
{
margin:0px auto;
padding: 0px;
font-family: Verdana, Helvetica, Arial, sans-serif;
font-size: 1.0em;
text-align: left;
background: #fff;
color: #000;
}
div.wrapper
{
width: 921px;
margin: 0px auto;
text-align: center;
}
div.maincontainer
{
width:960px;
text-align: left;
}
And then in your HTML code, something like
<div id="wrapper">
<div id="maincontainer">Lorem Ipsum
</div>
</div>
