title: Browser scroll jump when div height is set to 100% on mobile browsers
body: <p>Dropbox recently updated their website layout where the first div occupies 100% of the window size and vertically centers the content irrespective of the browser height. </p>
  
  <p>I am trying this layout for my own website. However I noticed when I open the website in chrome on my mobile on scroll there is an initial jump and then the page seems fine. </p>
  
  <p>How do i get rid of this scroll jump?</p>
  
  <p>You can check the same by visiting the <a href="https://www.dropbox.com/" rel="nofollow noreferrer">Dropbox</a> website on you mobile (Android or iOS)</p>
  
  <p>[<strong>UPDATE</strong>] This happens when you scroll and the address bar hides. </p>
