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', {
    speed: -2,
    center: false,
    wrapper: null,
    round: true,
    vertical: true,
    horizontal: false
  });
</script>

Features

Speed

Use the data-rellax-speed attribute to set the speed of a .rellax element to something other than the default value (which is -2). A negative value will make it move slower than regular scrolling, and a positive value will make it move faster. We recommend keeping the speed between -10 and 10.

Responsive Speed

Use responsive speed attributes for breakpoint levels that require a different speed. Defaults to the data-rellax-speed setting in unspecified breakpoints.

<div class="rellax" data-rellax-speed="7" data-rellax-xs-speed="-5" data-rellax-mobile-speed="3" data-rellax-tablet-speed="-8" data-rellax-desktop-speed="1">
  I parallax at all different speeds depending on your screen width.
</div>

Pass an array of breakpoints (mobile, tablet and desktop respectively).

<script>
  // This is the default setting
  var rellax = new Rellax('.rellax', {
    breakpoints: [576, 768, 1201]
  });
</script>

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>

Z-index

If you want to sort your elements properly in the Z space, you can use the data-rellax-zindex property

<div class="rellax">
  I’m that default chill speed of "-2" and default z-index of 0
</div>
<div class="rellax" data-rellax-speed="7" data-rellax-zindex="5">
  I’m super fast!! And on top of the previous element, I'm z-index 5!!
</div>

Horizontal Parallax

Horizontal parallax is disabled by default. You can enable it by passing horizontal: true in the settings block. This feature is intended for panoramic style websites, where users scroll horizontally instead of vertically. Note that this can work together at the same time with the default vertical parallax. If you do not want this, pass vertical: false in the settings block.

Custom Wrapper

By default, the position of parallax elements is determined via the scroll position of the body. Passing in the wrapper property will tell Rellax to watch that element instead.

<script>
  // Set wrapper to .custom-element instead of the body
  var rellax = new Rellax('.rellax', {
    wrapper: '.custom-element'
  });
</script>

Refresh

<script>
  // Start Rellax
  var rellax = new Rellax('.rellax');

  // Destroy and create again parallax with previous settings
  rellax.refresh();
</script>

Destroy

<script>
  // Start Rellax
  var rellax = new Rellax('.rellax');

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

Callback

<script>
  // Start Rellax
  var rellax = new Rellax('.rellax-blur-card', {
    callback: function(positions) {
      // callback every position change
      console.log(positions);
    }
  });
</script>

Target node

Instead of using a className you can use a node, handy when using React and you want to use refs instead of className.

<div ref={ref => { this.rellaxRef = ref }}>
  I’m that default chill speed of "-2"
</div>

var rellax = new Rellax(this.rellaxRef)

Development

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

1. Open demo.html
2. Make code changes and refresh browser
3. Once feature is finished or bug fixed, use jshint to lint code
4. Fix lint issues then use Google Closure Compiler to minify
5. 🍻
