I have a split screen slider that works fine on desktop but I needed jQuery UI to make it work on mobile.The draggable event lets me drag it back and forth but sometimes the image on the left moves from it's original position, or disappears altogether. Any ideas on how to approach this?

Here's the codepen. The slider bug is more visible on mobile devices.

document.addEventListener('DOMContentLoaded', function(){
  let wrapper = document.getElementById('wrapper');
  let topLayer = wrapper.querySelector('.top');
  let handle = wrapper.querySelector('.handle');
  let skew = 0;
  let delta = 0;
  
  if(wrapper.className.indexOf('skewed') != -1){
   skew = 1000;
   }

wrapper.addEventListener('mousemove', function(e){
  delta = (e.clientX - window.innerWidth / 2) * 0.5;
  
  handle.style.left = e.clientX + delta + 'px';
  
  topLayer.style.width= e.clientX + skew + delta + 'px';
  });
});

$(".content-wrap").draggable({
  containment: "parent",
  dragx: true,
  dragy: false,
  rotate: false
});

body{
  margin: 0;
  padding:0;
  font-size: 100%;
  line-height: 1.6;
  font-family: Arial, Helvetica, sans-serif;
}

#wrapper{
  position: relative;

  width: calc(50vw + 1000px);
}

Forget the draggable as it is causing conflict with the mousemove event listener. I have used the touchmove event listener for mobile device. CODEPEN

wrapper.addEventListener("touchmove", function(e) {
  delta = (e.changedTouches[0].clientX - window.innerWidth / 2) * 0.5;
  handle.style.left = e.changedTouches[0].clientX + delta + "px";
  topLayer.style.width = e.changedTouches[0].clientX + skew + delta + "px";
});

Note: You may also enable/disable the touchmove and mousemove depending on the device type (touch or not).

Hope this helps.
