CSS:

<script type="text/javascript">
// I hope this over-commenting helps. Let's do this!
// Let's use the 'active' variable to let us know when we're using it
let active = false;

// First we'll have to set up our event listeners
// We want to watch for clicks on our scroller
document.querySelector('.scroller').addEventListener('mousedown',function(){
active = true;
// Add our scrolling class so the scroller has full opacity while active
document.querySelector('.scroller').classList.add('scrolling');
});
// We also want to watch the body for changes to the state,
// like moving around and releasing the click
// so let's set up our event listeners
document.body.addEventListener('mouseup',function(){
active = false;
document.querySelector('.scroller').classList.remove('scrolling');
});
document.body.addEventListener('mouseleave',function(){
active = false;
document.querySelector('.scroller').classList.remove('scrolling');
});

// Let's figure out where their mouse is at
document.body.addEventListener('mousemove',function(e){
if (!active) return;
// Their mouse is here...
let x = e.pageX;
// but we want it relative to our wrapper
x -= document.querySelector('.wrapper').getBoundingClientRect().left;
// Okay let's change our state
scrollIt(x);
});

// Let's use this function
function scrollIt(x){
let transform = Math.max(0,(Math.min(x,document.querySelector('.wrapper').offsetWidth)));
document.querySelector('.after').style.width = transform+"px";
document.querySelector('.scroller').style.left = transform-25+"px";
}

// Let's set our opening state based off the width,
// we want to show a bit of both images so the user can see what's going on
scrollIt(150);

// And finally let's repeat the process for touch events
// first our middle scroller...
document.querySelector('.scroller').addEventListener('touchstart',function(){
active = true;
document.querySelector('.scroller').classList.add('scrolling');
});
document.body.addEventListener('touchend',function(){
active = false;
