title: Shift anchor tags in HTML generated from Markdown, by Jekyll
body: <p>A web site I'm working on has a fixed navigation bar at the top. This messes up the positioning of anchor tags. I am aware of the <a href="https://stackoverflow.com/questions/10732690/offsetting-an-html-anchor-to-adjust-for-fixed-header">standard solution</a> to this problem, but I'm not sure how I could apply it here.</p>
  
  <p>Markdown source:</p>
  
  <pre><code>Go to [closing notes](#closing-notes).
  
  ### Closing Notes
  </code></pre>
  
  <p>HTML generated by Jekyll:</p>
  
  <pre><code>&lt;p&gt;Go to &lt;a href="#closing-notes"&gt;closing notes&lt;/a&gt;.&lt;/p&gt;
  
  &lt;h3 id="closing-notes"&gt;Closing Notes&lt;/h3&gt;
  </code></pre>
  
  <p>Any idea greatly appreciated.</p>
