Interactive Split Screen Animation In jQuery

An interactive skewed split-screen animation written in jQuery and CSS/CSS3 that allows you to reveal (compare) two overlapping layers with mouse movement.

How to use it:

1. Insert top/bottom layers to the split screen.

<section id="wrapper" class="skewed">
  <div class="layer bottom">
    <div class="content">
      <div class="content-body">
        <h1>Lay 1</h1>
        <p>Lay 1 Content</p>
      </div>
    </div>
  </div>
  <div class="layer top">
    <div class="content">
      <div class="content-body">
        <h1>Lay 2</h1>
        <p>Lay 2 Content</p>
      </div>
    </div>
  </div>
</section>

2. Create a skewed splitter at the bottom of the split screen.

<section id="wrapper" class="skewed">
  ...
  <div class="handle"></div>
</section>

3. The necessary CSS styles for the split screen.

#wrapper {
  position: relative;
  width: 100%;
  min-height: 55vw;
  overflow: hidden;
}

.layer {
  position: absolute;
  width: 100vw;
  min-height: 55vw;
  overflow: hidden;
}

.layer .content {
  position: absolute;
  width: 100vw;
  min-height: 55vw;
}

.layer .content-body {
  width: 25%;
  position: absolute;
  top: 50%;
  text-align: center;
  transform: translateY(-50%);
  color: #fff;
}

.layer h1 {
  font-size: 2em;
}

.bottom {
  background: rgb(34, 34, 34);
  z-index: 1;
}

.bottom .content-body {
  bottom: 40%;
  right: 5%;
}

.bottom h1 {
  color: #fdab00;
}

.top {
  background: rgba(180,167,150);
  color: #222;
  z-index: 2;
  width: 50vw;
}

.top .content-body {
  top: 30%;
  left: 5%;
  color: #222;
}

.handle {
  position: absolute;
  height: 100%;
  display: block;
  background-color: #fdab00;
  width: 3px;
  /* border: solid black 1px; */
  top: 0;
  left: 50%;
  z-index: 3;
}

.skewed .handle {
  top: 50%;
  transform: rotate(30deg) translateY(-50%);
  height: 200%;
  transform-origin: top;
}

.skewed .top {
  transform: skew(-30deg);
  margin-left: -1000px;
  width: calc(50vw + 1000px);
}

.skewed .top .content {
  transform: skew(30deg);
  margin-left: 1000px;
}

4. The split screen requires the latest jQuery to work properly.

<script src="/path/to/cdn/jquery.min.js"></script>

5. The main JavaScript (jQuery script) to activate the split screen.

$(document).ready(function () {
  if ($('#wrapper').hasClass('skewed')) skew = 1000;
  $("#wrapper").mousemove((event) => {
    delta = (event.clientX - window.innerWidth / 2) * 0.5;
    value = event.clientX + delta;
    $(".handle").css("left", value + 'px');
    $(".top").css("width", value + skew + 'px');
  });
});
