title: How to make a DIV stick to the side of a fixed width element in an otherwise-fluid design
body: <p>I've got a fluid content area with padding and a fixed-width sidebar.  I'm wanting to <code>float: right</code> an image and give it a negative <code>margin-right</code> equal to the container's <code>padding</code> to get the floated image to abut the sidebar.</p>
  
  <p>Code is worth a thousand words... </p>
  
  <p>Here's a reduced test case is here that shows the problem: <a href="http://jsfiddle.net/alexdunae/34ZDw/3/" rel="nofollow">http://jsfiddle.net/alexdunae/34ZDw/3/</a>  -- shrink or expand the preview pane to see.</p>
  
  <p>It's seems that my negative margin calculation must be off somewhere.  Any help is much appreciated.</p>
