This plugin is mainly for adding animations to older versions of Compass.

  • The latset version of Compass has this code merged in, so there's no need for this plugin. We're not updating it anymore.
  • If you are looking for Dan Eden's Animate.css ported to Compass, try the compass-animate plugin.

Animation Compass Plugin

First and foremost, this plugin gives you all the tools you need to write and apply css3 animations in compass. As a bonus, and only if you so choose, it also supplies you with a "shit-ton" (roughly 2 metric tons) of pre-fabricated animations taken from Dan Eden's "Animate.css" project.

This plugin requires Sass 3.2 and Compass 0.12

gem install animation --pre

require 'animation'

@import "animation";


The default import only includes the core mixins for creating animations. That covers all the expected properties, to be used exactly as you would in CSS:

// create your animation
@include keyframes($name) {

// apply animation(s) and adjust settings
@include animation-name([$name-1, $name-2, ..., $name-10]);
@include animation-duration([$duration-1, $duration-2, ..., $duration-10]);
@include animation-delay([$delay-1, $delay-2, ..., $delay-10]);
@include animation-timing-function([$function-1, $function-2, ..., $function-10]);
@include animation-iteration-count([$count-1, $count-2, ..., $count-10]);
@include animation-direction([$direction-1, $direction-2, ..., $direction-10]);
@include animation-fill-mode([$mode-1, $mode-2, ..., $mode-10]);
@include animation-play-state([$state-1, $state-2, ..., $state-10]);

// shortcut to apply and adjust
@include animation([$animation-1, $animation-2, ..., animation-10]);

There are default variables available for all of them:

$default-animation-name             : false;
$default-animation-duration         : false;
$default-animation-delay            : false;
$default-animation-timing-function  : false;
$default-animation-iteration-count  : false;
$default-animation-direction        : false;
$default-animation-fill-mode        : false;
$default-animation-play-state       : false;

For Example

Say you want to create your own animation. Start with the keyframes:

@include keyframes(my-animation) {
  0%, 100% {
    background-color: blue;
  50% {
    background-color: red;

That animation will change the background color from blue to red to blue again. Now let's apply it to something:

body {
  @include animation(my-animation 10s infinite);

Compare that to the official CSS spec:

@keyframes my-animation {
  0%, 100% {
    background-color: blue;
  50% {
    background-color: red;

body {
  animation: my-animation 10s infinite;

Pretty much identical. You're just using include/argument pairs instead of property/value pairs.


Because the Animate code creates output, you need to import it (or one of it's sob-modules) directly:

@import "animation/animate";

That will create the following named animations:

  • Attention seekers
    • flash, bounce, shake, tada, swing, wobble, wiggle, pulse
  • Flippers (currently Webkit, Firefox, & IE10 only)
    • flip, flipInX, flipOutX, flipInY, flipOutY
  • Fading entrances
    • fadeIn, fadeInUp, fadeInDown, fadeInLeft, fadeInRight, fadeInUpBig, fadeInDownBig, fadeInLeftBig, fadeInRightBig
  • Fading exits
    • fadeOut, fadeOutUp, fadeOutDown, fadeOutLeft, fadeOutRight, fadeOutUpBig, fadeOutDownBig, fadeOutLeftBig, fadeOutRightBig
  • Bouncing entrances
    • bounceIn, bounceInDown, bounceInUp, bounceInLeft, bounceInRight
  • Bouncing exits
    • bounceOut, bounceOutDown, bounceOutUp, bounceOutLeft, bounceOutRight
  • Rotating entrances
    • rotateIn, rotateInDownLeft, rotateInDownRight, rotateInUpLeft, rotateInUpRight
  • Rotating exits
    • rotateOut, rotateOutDownLeft, rotateOutDownRight, rotateOutUpLeft, rotateOutUpRight
  • Lightspeed
    • lightSpeedIn, lightSpeedOut
  • Specials
    • hinge, rollIn, rollOut

You can use them like this:

.widget {
  @include animation(fadeIn);

You can also import a set of predefined classes for each animation:

@import "animation/animate/classes";

With those classes imported, you can simply add the class of fadeIn to any element, and watch it do the magic.

That's all there is to it.
