Parallax.js - Javascript

Parallax.js is a Javascript library that can be used to create parallax effects on your website. It allows you to create depth and dimension in your website by moving different layers of content at different speeds.

Installation

You can easily install Parallax.js by using npm:

npm install parallax-js

Usage

Once you have installed Parallax.js, you can include it in your project and start using it right away. Here's an example of how you can create a parallax effect on an image:

<div class="parallax-window" data-parallax="scroll" data-image-src="path/to/image.jpg"></div>

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

In this example, we have a div element with a class of parallax-window. We have added two data attributes to it: data-parallax with a value of scroll, and data-image-src with the path to the image we want to use for the parallax effect.

Configuration

Parallax.js comes with several configuration options that you can use to customize the parallax effect to your liking. Here are some of the most commonly used options:

$('.parallax-window').parallax({
  naturalWidth: 600,
  naturalHeight: 400,
  speed: 0.5
});

• naturalWidth - the width of the image used for the parallax effect
• naturalHeight - the height of the image used for the parallax effect
• speed - the speed at which the parallax effect should be applied (default is 0.2)

Advanced Usage

Parallax.js also allows you to create more complex parallax effects that involve multiple layers of content. Here's an example of how you can create a parallax effect with three layers:

<div class="parallax-window">
  <div class="parallax-layer parallax-layer-base"></div>
  <div class="parallax-layer parallax-layer-back"></div>
  <div class="parallax-layer parallax-layer-front"></div>
</div>

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

In this example, we have a div element with a class of parallax-window. Inside this element, we have three div elements with classes of parallax-layer. We have also added classes of parallax-layer-base, parallax-layer-back, and parallax-layer-front to these elements to indicate their order in the parallax effect.

Here's how you can configure the parallax effect for this example:

$('.parallax-window').parallax({
  layers: [
    {
      layer: $('.parallax-layer-base'),
      amount: 0.1
    },
    {
      layer: $('.parallax-layer-back'),
      amount: 0.3
    },
    {
      layer: $('.parallax-layer-front'),
      amount: 0.5
    }
  ]
});

In this example, we have added a layers option to the configuration and provided an array of objects that specify the layer element and the amount of parallax effect to apply to it. The amount is a value between 0 and 1, indicating the percentage of the parallax effect to apply.
