How do I narrow my forum width and center it?

[Rho Delta]

I've done this once before but have forgotten how and can't find where I made the change. Help? Thanks!

How do I create a fixed width style?
In the ACP -> Styles -> Style Properties -> General: Page Width Controller, enter the following settings in the Miscellaneous field (change the values to suit):

width: 992px;​

margin: 0 auto;​
