title: Page transition animation similar to Medium.com
body: <p>I'm trying to find out how does medium do the animation when you click the bottom button to load the next article. </p>
  
  <p>To see it, please head over to a <a href="https://medium.com/on-publishing/3895f4d045d2" rel="nofollow">Medium article</a>, scroll to bottom and click to go to the next article. </p>
  
  <p>I know how to use AJAX to load another page, but how can I use a similar animation ? I've searched through their code, but couldn't find it.</p>
