title: Why is the expanding card preview text increasing after being opened and closed?
body: <p>I have found this Codepen that I wish to use and it's perfect apart from the fact that once you open and close a card, the preview text reveals more than before it was opened.</p>

  <p>I think it has something to do with this class however I'm not entirely sure</p>
  
  <pre><code>&lt;div class='expd-truncate'&gt;
  </code></pre>
  
  <p>This is the link to the Codepen, any help is greatly appreciated.</p>
  
  <p>Thanks</p>
