title: How do I get Sphinx code blocks working as tabs?
body: <p>I have tried the extension sphinx-tabs. I use Python 3.8 and the latest Sphinx ver.</p>
  
  <p>I install with pip and add to conf.py but my code is never displayed properly. </p>
  
  <p>In conf.py I have this:
  extensions = ['sphinx_tabs.tabs']</p>
  
  <p>My code is simple:</p>
  
  <pre><code>.. tabs::
      .. tab:: tab1
          Content for tab one
  
      .. tab:: tab2
          Content for tab two
  </code></pre>
  
  <p>This just produces the text:</p>
  
  <p>tab1</p>
  
  <p>tab2</p>
  
  <p>Both appear to be hyperlinks but do not actually link anywhere.</p>
