How to use it:

1. Insert your images into the slider container.

<div class=container>
  <div id="proparallax">
    <img class="one" src="1.jpg" /> 
    <img class="two" src="2.jpg" />
    <img class="three" src="3.jpg" />
  </div>
</div>

2. The primary CSS styles for the slider.

#proparallax {
  display: block;
  position: relative;
  overflow: hidden;
  min-height: 37.5rem;
  border: 10px solid black;
  box-shadow: 0px 8px 10px 8px grey;
} 

#proparallax img {
  position: absolute;
  width: 50rem;
  height: 37.5rem;
  overflow: hidden;
  object-fit: cover;
}

3. Apply parallax scrolling effects to images.

#proparallax img.one{
  animation-name: parallax_one; /* controls img.one movement */
  animation-timing-function: linear;
  animation-iteration-count: infinite;
  animation-duration: 18s;
  animation-direction: forwards;
  object-fit: cover;
}

#proparallax img.two {
  animation-name: parallax_two; /* controls img.two movement */
  animation-timing-function: linear;
  animation-iteration-count: infinite;
  animation-duration: 18s;
  animation-direction: forwards;
  object-fit: cover;
}

#proparallax img.three {
  animation-name: parallax_three; /* controls img.three movement */
  animation-timing-function: linear;
  animation-iteration-count: infinite;
  animation-duration: 18s;
  animation-direction: forwards;
  object-fit: cover;
}
