Usage

#1

Include the script in your project.

<script src="node_modules/universal-parallax/dist/universal-parallax.min.js"></script>

#2

Choose between either..

Including <link href="node_modules/universal-parallax/dist/universal-parallax.min.css" rel="stylesheet"> in your <head> section
Or adding this CSS

.parallax--container {
	position: absolute;
	clip: rect(0, auto, auto, 0);
	width: 100%;
	height: 100%;
	top: 0;
	left: 0;
	z-index: -10;
}

.parallax {
	position: fixed;
	width: 100%;
	height: 100%;
	top: 0;
	left: 0;
	/* optional */
	background-repeat: no-repeat;
	background-position: center;
	background-size: cover;
}

#3

If <section> is your container, make the parallax element inside it, just before the closing tag.

<section>
	...
	<div class="parallax" data-parallax-image="path/to/your_image">
</section>

You can also use a class to define your background-image in CSS, instead of using data-parallax-image="".

#4

Fire up the JS function.

new universalParallax().init();

Custom speed

You can change the parallax speed.

new universalParallax().init({
	speed: 6.0
});

Note: speed: 1.2 is the minimum value before the background image is fixed.

Opacity

If desired, transparency can be added to one, or all parallax elements and it won't affect the opacity of your content above.

.parallax {
	opacity: 0.5;
}
