title: How can I get a Bootstrap column to span multiple rows?
body: <p>I'm trying to figure out how to do the following grid with Bootstrap. </p>
  
  <p>I'm not sure how I'd create the box (number 1) that spans two rows. The boxes are generated programmatically in the order they are laid out. Box 1 is a welcome message.</p>

  <p>Any ideas on the best way to go with this?</p>
