title: Enable line numbers for specific markdown code listings designated with backticks
body: <p>I am using MkDocs with the codehilite markdown extension</p>
  
  <p>I would like to enable code snippet line numbers only for specific snippets. </p>
  
  <p>If I set </p>
  
  <pre><code>markdown_extensions:
    - codehilite:
        linenums: true
  </code></pre>
  
  <p>in my mkdocs.yml, this will enable line numbers for all code snippets.</p>
  
  <p>I see that it is possible to activate line numbers for specific snippets by using the shebang language specifier together with double indentation:</p>
  
  <pre><code>#!python
  """ Bubble sort """
  def bubble_sort(items):
      for i in range(len(items)):
          for j in range(len(items) - 1 - i):
              if items[j] &gt; items[j + 1]:
                  items[j], items[j + 1] = items[j + 1], items[j]
  </code></pre>
  
  <p>However, I prefer using backticks (```) for designating code. </p>
  
  <p>Is there a way to enable line numbers for specific code listings when using backticks?</p>
