title: Background color/image bug when using [margin: 0 auto;] on inner div
body: <p>In my example (link below) some of the background of the OUTER DIV magically disappears when the browser size goes smaller than the defined width of the INNER DIV (960px). The horizontal scrollbar kicks in, as expected, but when you scroll to the right you don't get to see the missing section of the image. I believe it has something to do with the INNER DIV's property of [margin: 0 auto;], because when the INNER DIV is taken out of the code, the OUTER DIV's background shows as it should (it gets cutoff, but no scroll bar).</p>
  
  <p>Anyone have any ideas why this is happening...and how to fix it?:</p>
