400773 Fix web site page alignments

Simple task. My website has header sections that properly float towards the center of the page when the browser window is expanded beyond the size of the page. However, the main body section floats left and does not align under header when the browser window is expanded. Need to fix on templates and pages. This can probably be done sitewide modifying the css style sheet. The site is [login to view URL] The [login to view URL] page is a good example. There are 30 pages and 5 templates, but I expect the fix is a few minutes on the style sheet for most pages.
