title: Changing default starting position of #anchor
body: <p>I have a URL with an anchor that is working as it should:</p>
  
  <pre><code>site.com/item/id#comment-233
  </code></pre>
  
  <p>When opened, the anchor will be positioned at exactly the top of the page.</p>
  
  <p>How do I change the starting point? Let's say I want it to be <code>50px</code> down from the top. </p>
  
  <p>The reason I'm needing this is because I have fixed layers at the top of the page, so the comment is appearing overlapped behind the fixed header <code>div</code>. </p>
  
  <p>Just in case, because of cross-browser compliance I prefer a solution that does not involve changing the container of the comment to fixed and positioning top minus the height of the header. </p>
