title: iOS right side whitespace after CSS3 animation
body: <p>On the website <a href="https://swap-n-sell.com" rel="nofollow noreferrer">https://swap-n-sell.com</a> does the right side get a whitespace on iOS. In other browser it works. The whitespace appears when I open the sidebar and close it with the button on the top left corner:</p>

  <p>The sidebar opens/closes with a CSS3 animation. After it's closed I get on the right side this whitespace:</p>

  <p>I inspected it with the Webinspector and added <code>margin-right: 0%;</code> to the body. Suddenly the whitespace was removed but when I opened the sidebar again then the whitespace was also again there. Maybe the view doesn't refresh or something like that I don't know. Thanks for your help.</p>
