The content background color appears to get applied to #main-wrapper which is the container for #main which holds the actual content. I think when you specify Content area background color, its not really defining color for the content area but rather the wrapper around the content that spans the page which makes the primary menu width and content area width not match up. Thats my thought anyway.... close the issue if I'm clearly wrong but it seems as though the style should be applied to #main.

apmsooner commentedJust to clarify, when I set fluid width of 95%, it applies the css property of width:95% to #main div.

ajross commentedYou're absolutely right. I did most of my testing of fluid layout on the 100% setting, so I missed this. I'm glad you caught the problem. I will rework the CSS to correct it and try to get out a new release soon, as this is a pretty basic problem. Thanks!

ajross commentedOk, I think this is fixed in the latest release (version 1.3) of the theme. Let me know if you still run into any problems though.
