title: CSS background-image won't show with short URL
body: <p>I've done my searching and the topics haven't been of help.</p>
  
  <p>I'm trying to have the background image of my header repeat across the X axis of the header div.</p>
  
  <p>When I make CSS with a long URL such as</p>
  
  <p><code>background-image:url('http://site.com/images/logo.png');</code> everything works fine</p>
  
  <p>When I try to shorten the CSS to something such as ~/images/ or even having the CSS and site file already in the root folder and using /images/ I get nothing</p>
  
  <pre><code>background-image:url('~/images/logo.png')
  
  background-image:url('/images/logo.png')
  </code></pre>
