title: Bootstrap anchor offset issue
body: <p>I'm using Bootstrap with the Slate theme here: <a href="http://bootswatch.com/slate/" rel="nofollow">http://bootswatch.com/slate/</a></p>
  
  <p>When jumping to different anchors on the same page, it's offset and doesn't go to the exact content section it should (or not display right).</p>
  
  <p>For example: <a href="http://bootswatch.com/slate/#nav" rel="nofollow">http://bootswatch.com/slate/#nav</a></p>
  
  <p>This is intended to jump to the "Navs" section and it almost does, but it's slightly offset down and you cannot see the title.</p>
  
  <p>I'm experiencing the same issue on my own site with this theme, how can I fix this anchor issue?</p>
  
  <p>I'm doing the basic:</p>
  
  <pre><code>&lt;a href="#nav"&gt;Jump to Nav&lt;/a&gt;
  
  ...
  
  &lt;a id="nav"&gt;Navs&lt;/a&gt;
  </code></pre>
