🎉 Hiring Designers: Are you using Rellax on a project? Does having a 🍺/☕️/🍵, playing Soundcloud remixes, and experimenting with new design and code ideas get you all giddy? Yea, us too 😜. We're hiring a Junior Frontend Designer in San Francisco (sorry no remote). Let's chat robert@dixonandmoe.com.

Getting Started

npm install rellax --save or if you're old school like us download and insert rellax.min.js

<div class="rellax">
  I’m that default chill speed of "-2"
</div>
<div class="rellax" data-rellax-speed="7">
  I’m super fast!!
</div>
<div class="rellax" data-rellax-speed="-4">
  I’m extra slow and smooth
</div>

<script src="rellax.min.js"></script>
<script>
  // Accepts any class name
  var rellax = new Rellax('.rellax');
</script>

<script>
  // Also can pass in optional settings block
  var rellax = new Rellax('.rellax');
</script>

Features

Centering

After some fantastic work from @p-realinho, we just released the ability to center parallax elements in your viewport! We'll be building a nice demo website, but for now check out the tests folder for several examples of how it works.

There's two ways to implement centering, either on specific elements or as a global option.

<div class="rellax" data-rellax-percentage="0.5">
  I’m that default chill speed of "-2" and "centered"
</div>
<div class="rellax" data-rellax-speed="7" data-rellax-percentage="0.5">
  I’m super fast!! And super centered!!
</div>
<div class="rellax" data-rellax-speed="-4" data-rellax-percentage="0.5">
  I’m extra slow and smooth, and hella centered.
</div>

<script>
  // Center all the things!
  var rellax = new Rellax('.rellax', {
    center: true
  });
</script>

Destroy

<script>
  // Start Rellax
  var rellax = new Rellax('.rellax');
  
  // End Rellax and reset parallax elements to their original positions
  rellax.destroy();
</script>

In the Wild

If you're using Rellax in production, we'd love to list you here! Let us know: moe@dixonandmoe.com

Development

In the spirit of lightweight javascript, the build processes (thus far) is lightweight also.

Open demo.html
Make code changes and refresh browser
Once feature is finished or bug fixed, use jshint to lint code
Fix lint issues then use Google Closure Compiler to minify
