HTML/JavaScript smooth parallaxe effect library orginally developed for Boy-Coy.

This library is under development. API may change.

• jQuery
• Modernizr
• requestAnimationFrame polyfill (for older browsers only)

To download parallaxer.js you can use bower:

bower install parallaxer.js

Bower will also download dependences.

Alternatively, you can manually download the minified library (can be found in dist directory).

Having .js files in place you can include them in your HTML.

<script src="bower_components/parallaxer.min.js"></script>

Don't forget to include dependences.

Now you can add data attributes to HTML elements that will be parallaxed, e.g.:

<div data-parallaxer="enabled" data-parallaxer-speed="1"></div>
<div data-parallaxer="enabled" data-parallaxer-speed="0.5"></div>

Each element will create separate parallaxe layer. Value of data-parallaxer-speed argument will decide how fast each element will move relatively to normal scroll speed.

Because of the nature of this parallaxe library all elements have to be "parallaxe enabled", otherwise they won't move as smooth as "parallaxe enabled" elements. If you want them to move with "normal" scroll speed just leave data-parallaxer-speed value set to 1.

Of course you can nest other elements in parallaxe enabled ones.

The last step is to call start method when HTML is loaded:

$('document').ready(function () {
    andrzejdus.parallaxer.Parallaxer.start();
});

For simple usage example look to example directory.
