title: 'Wheel' events on touch screens
body: <p>I have this fiddle <a href="https://jsfiddle.net/316n1xmL/1/" rel="noreferrer">https://jsfiddle.net/316n1xmL/1/</a> which works perfectly how I need it to on desktop. Counts up or down based on wheel scroll direction and adds and removes classes. The issue I am running into is how to do this on touch screens. </p>
  
  <p>I have tried hammer.js but their documentation is really bad and not clear. </p>
  
  <p>Sadly the site I am building is using bootstrap 4 which means I cannot use juqery mobile since BS4 uses jquery 3 which does not support jquery mobile.</p>
  
  <p>Any help is appreciated</p>
