Pure CSS Image Comparison Slider

Description:

A pure HTM/CSS image comparison slider made using range slider input and  CSS :after and :before pseudo classes for the slider thumb.

<input type='range' value='50'>

input[type='range'] {
  -webkit-appearance: none;
  -moz-appearance: none;
  background: none;
  display: block;
  cursor: pointer;
  margin: 0 auto;
  height: 10px;
  width: 444px;
  left: -10px;
  position: relative;
}
input[type='range']:after {
  content: '';
  width: 900px;
  position: absolute;
  height: 100vh;
  left: 31px;
  top: -8px;
  background-image: url(after.png);
  display: block;
  background-position: left;
  background-size: 400px;
  background-repeat: no-repeat;
}
input[type='range']:focus { outline: none; }
input[type='range']::-webkit-slider-thumb {
 -webkit-appearance: none;
 height: 30px;
 width: 15px;
 border-radius: 3px;
 background: #b378ef;
