How do I change the width of the entire page and center it?

The default page width takes up 100% of the screen, and does so because of the following code in the MediaWiki:Common.css file:
#globalWrapper {
font-size: 127%;
width: 100%;
margin: 0; padding: 0;}
If you want the content of the page to take up 900px and be centered on the screen, make the following adjustments:
#globalWrapper {
position:relative;
font-size: 127%;
width: 900px;
margin-left:auto;
margin-right:auto;
padding: 0;
}
