title: Sliding mobile nav overflow
body: <p>I'm working on a mobile navigation option for my site and want it to slide from the right.</p>
  
  <p>Here's a mockup:</p>
  
  <p><a href="https://codepen.io/rctneil/pen/OqzBjX" rel="nofollow noreferrer">https://codepen.io/rctneil/pen/OqzBjX</a></p>
  
  <p>The issue I have is that by default the page scrolls over to the right when the nav is hidden.</p>
  
  <p>I've tried adding <code>overflow: hidden</code> to <code>.mega-wrapper</code> which stops this scroll, but also hides the navigation when the toggle button is clicked.</p>
  
  <p>Any ideas?</p>
  
  <p>Kind regards,
  Neil</p>
