title: Twitter Bootstrap nav-bar overlapping Drupal Admin bar
body: <p>I'm working on a site using Drupal 7 and Twitter Bootstrap. I have a navigation bar on top of my page.
  When I log in as admin in Drupal, the admin bar appears. These 2 navigation bars overlap each other.</p>

  <p>How can I prevent this? I want the Twitter nav-bar always on top of my page, but when I'm logged in on Drupal I want it to be below the Drupal bar.</p>
