Trying to set a site wide maximum width in Carson template

Hi,

I can't seem to figure out a way to set a site wide maximum width for a site I'm working on. Nothing in custom css I've tried worked. I'm using the Carson template, and it doesn't have page max width options under design.

Any help would be greatly appreciated.

div#mainContent {
    max-width: 900px;
    margin-left: auto;
    margin-right: auto;
}

Worked! Thanks a lot!
