I've noticed that my web site is too wide on smaller screens while the XOOPS web site does a better job of shrinking the center section when the window it's smaller. Where is this controlled and how do I change my site? I would like to both allow the center section to get smaller and shrink the left and right sides a little to help make my site work better on smaller monitors.

I notice that on the XOOPS site, the left and right sides even can shrink while mine never do.

edit - I found part of my problem - my banner add was constraining the minimum width. Now what I want to change is this. When the window grows, my left and right sections get wider. I would like them to simply stay a fixed width and have my center section get all of the extra width. Where is that controlled and how do I change it.

thanks

You need to edit your theme to reflect the constraints you wish to see. The limits can be in either the theme.html or style.css files (most often).
