center float.

Ok i'm coding a layout in expandable divs with html and css, i currently have a banner type div which is set to a 0px margin and 100% width and a main content box which also has a 0px margin, and a 550px width. I want the content box to be in the center of the page with the top touching the bottom of the banner (0px margin). So far it looks like this.

Now, i want the main content box centered, I could do this using the margin-left or margin-right but it would only look right in my monitor/browser; it would be out of place for everyone else.

How could i resolve this? I looked up float:center but thats not valid css.

margin-left: auto;
margin-right: auto;

Or you can do it much simplier:

margin: auto;
