title: "Break out" of DIV with padding?
body: <p>If I have a 100% wide div element with 12 pixels of <code>padding</code> to the left and to the right, and I have an element inside the div that I want to span from one corner of the screen to another (bridging the 12 pixel gap), do I have any chance of "breaking out" of the surrounding div without using absolute positioning? </p>
  
  <p>Using <code>position:relative; left:-12px</code> won't work alone, because the div is 100% wide and I can't specify "100% + 12px" to make the inner element touch the right hand corner.</p>
