I really love how Twenty Eleven can easily handle using fluid width (width not hard coded but it self adjusts to the user’s screen resolution). I can get the content areas to fill the page nicely on a template with sidebar. Between the post and the sidebar the screen is nicely filled. Is there any way to have the single column default template also fill the screen. You can see what I mean at http://gregihnen.me (with sidebar) and http://gregihnen.me/test-of-default-template-no-sidebar.
