parallax-js is the real parallax scrolling, not just static backgrounds. This is simply done using (lightweight) vanilla javascript which animates the parallax elements based on the current scroll position in the page’s vertical scroll.

How to make use of it:

1. Add a parallax component to the web page.

<div class="container">
  <div class="parallax"></div>
</div>

2. Make the parent container relatively positioned.

.container {
  position: relative;
  overflow: hidden;
  height: 200vh;
}

3. The needed CSS styles for the parallax component.

.parallax {
  position: absolute;
  width: 100vw;
  height: 100%;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%) scale(1.15);
  z-index: -99;
  background-position: bottom;
  background-size: cover;
  background-image: url("bg.jpg");
}

4. Load the principle script parallax.js within the document.

<script src="parallax.js"></script>

5. Set the factor of displacement after every scroll. Between 0 to 10.

<div class="container" data-depth="5">
  <div class="parallax"></div>
</div>
