title: Responsive backgrounds with Twitter Bootstrap?
body: <p>I would like to have a responsive image arrangement for backgrounds on a site.  </p>
  
  <p>For example, based on different screen resolutions, I would like for different background images to load.  Further it would be useful if I could define different behaviors; for example, a higher resolution desktop would have a larger stretched background image, while a netbook might have a smaller version of that shrunk to fit, or while a 3GS iPhone would have a small tiled image.</p>
  
  <p>How would you implement such a scenario?</p>
