Animate

animate.js is a tiny library that helps you write smooth CSS-powered animations in JavaScript. See a quick demo of 500 elements animating at playground.deaxon.com/js/animate.

Usage

Include animate.min.js in your page:

<script src=animate.min.js></script>

Start animating things:

animate({
  el: "div",
  translateX: 100,
  opacity: .5,
  duration: 500,
  complete: function() { alert("Done!") }
});

API

animate requires a config object accepting the following options:

el

The elements you want to animate. el can be a:

CSS selector
DOM element
array of DOM elements
NodeList or HTMLCollection

duration

[Optional] The duration of your animation in milliseconds. Default: 400. ms will be added if you don't specify a unit.

delay

[Optional] The delay before your animation starts in milliseconds. Default: 0. ms will be added if you don't specify a unit.

easing

[Optional] The animation curve (CSS keyword or cubic-bezier). Default: ease.

complete

[Optional] A function called at the end of the animation. Inside the function, this refers to the DOM element that has finished animating.

animatable properties

opacity
translateX
translateY
translateZ
scaleX
scaleY
scaleZ
rotateX
rotateY
rotateZ
skewX
skewY
perspective

You can also use the shortcut transform functions translate, scale and rotate when the same value should be applied to X and Y:

translate: 100 // same as translateX: 100, translateY: 100

If you don't specify a unit, px will be added to translate-related and perspective functions and deg to rotate-related functions.
