title: How to display a blank div element?
body: <p>I have a blank div class that is called spacer ... it has a blue background and a width of 100% of the container (the body) ... </p>
  
  
  
  
  <p>What I have found is that the spacer will not DISPLAY unless I toss some character in it. I can color the character blue so it is hidden, but that is so inelegant. </p>
  
  <p>What is the CORRECT way to do this.</p>
