title: Flickering Issue on menu collapse
body: <p>When in the responsive/mobile view of <a href="https://rohiniartstudio.com/" rel="nofollow noreferrer">www.rohiniartstudio.com</a>
  When I click on the menu, the menu flickers on collapsing and displays the content below the menu.
  On default it was taking about 1-2s before it shows the menu items then added this code:</p>
  <pre><code>.collapsing 
  {
    -webkit-transition: none;
      transition: none;
      display: none;
  }
  </code></pre>
  <p>Can someone help me out with the flickering issue?
  Please visit the site and let me know?</p>
