I'm not great with CSS, so I need a little help. On the site, http://www.hood.army.mil/15sus, I have the layout the way I want it. Problem is that it looks really small on higher resolution screens, like my boss's 24 inch ... I have edited the CSS to accommodate a larger width, and centered the banner and footer, but I cannot get the menu and slideshow main divs to center. I tried putting them in a container div, like the whole page is, and set the margins to auto, but no dice. Any ideas? Attached is the current stylesheet.
