title: Fixed background doesn't get updated on Android
body: <p>I've found a similar question here but with no answer, yet I can't find an alternative as a solution.</p>
  
  <p>I have the following code and it works perfectly on Mac and Windows, however I can't figure out why on Android (either Chrome or Firefox) the background does not get updated when the user is scrolling down, it produces the space of about 1/5 of the screen at the bottom while scrolling down.
  The background image gets updated after you release the touch.</p>
  
  <pre><code>html{
    background-image:url(example.jpg);
    background-position:fixed;
    background-size:100% 100%;
  }
  </code></pre>
