title: Font Awesome z-index issues
body: <p>On a web project I'm working on I have a fixed navbar at the top of the page and the content underneath has Font Awesome icons sprinkled around.</p>
  
  <p>Initially, I was using a CDN link to FA and everything was rendering fine.
  When I tried using a local version retrieved through Bower, the icons were being rendered above the navbar while all other content was being rendered properly below.</p>
  
  <p>The z-index on the icons are set to auto for both CDN and local versions (Font Awesome version 4.6.0).
  I have tried modifying the icon z-index values manually to no avail.
  The issue appears on both Firefox and Chrome.</p>
  
  <p>Has anyone experienced this problem before?</p>
