0.1kb Background Parallax Scroll Plugin In jQuery

This is the smallest parallax scrolling library in the world I have ever seen.

It uses jQuery's scroll() function to track the scroll event and applies a subtle parallax scrolling effect to background images by adjusting the background-position property of them while scrolling the page.

How to use it:

1. Add the CSS class parallax-bg to the parallax container.

<section class="parallax-container parallax-bg">
  Parallax Container
</section>

2. Add a background image to the container.

.parallax-container {
  background-image: url(bg.jpg);
  background-size: cover;
  background-repeat: no-repeat;
}

3. Apply the parallax scrolling effect to the background image. Just paste and insert the following jQuery script after jQuery and done.

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

$(window).scroll(function () {
  parallax();
})

function parallax() {
  var wScroll = $(window).scrollTop();
  $('.parallax-bg').css('background-position',
    'center '+(wScroll*0.75)+'px')
}

4. Or directly load the parallax.js after jQuery.

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