Animate.less

Cross-browser CSS3 animation library

If you're a web hipster, and you're already using Twitter's Bootstrap like a whore, you're gonna love this.

animate.less, originally created by Dan Eden, is a bunch of cool, fun, and cross-browser animations converted into LESS for you to use in your Bootstrap projects. Great for emphasis, home pages, sliders, and general just-add-water-awesomeness.

Usage

Files

animate.css is 64kb and animate.min.css is 48kb.

Getting a Copy

You can use bower, npm, or download a zip.

bower

bower --save install animate.less

npm

npm --save install animate.less

Bootstrap/LESS

To use animate.less in your Bootstrap project, simply add the line below into bootstrap.less:

@import "<PATH_TO_SOURCE>/animate.less";

Inside your HTML

Add the class animated to an element, along with any of the animation names. That's it! You've got a CSS animated element. Super!

For example:

<h1 id="logo" class="animated fadeIn">...</h1>

Inside your stylesheet

Since we're using LESS, we can utilize our animation library by adding .animated and any of the many animation names as classes.

For example:

h1#logo {
  float: left;
  font-family: 'Cubano', sans-serif;
  font-weight: normal;
  font-size: 3.5em;
  text-transform: uppercase;
  padding: 0;
  margin: 0;
  .animated; // Initiate animation library
  .bounce; // Initiate bounce effect
}

Note: if you're having issues, try re-compiling bootstrap.less for changes to take effect.

Extending with jQuery

You can add more functionality to your animations with jQuery such as below:

$("#logo").addClass('animated bounceOutLeft');

We can also bind these classes with events or triggers like below:

$(document).ready(function(){
	$("#logo").click(function() {
		$("this").addClass("animated bounceOutLeft");
	});
});

Editing an animation effect

You can

  1. change the duration of your animations with the LESS varible @animationDurationTime
  2. extend the delay with LESS varible @animationDelayTime
  3. change the animation fill mode with the LESS variable @animationFillMode or
  4. change the number of times that it plays.

If you do edit an animation effect, make sure you change them cross-browser.

#logo {
	-vendor-animation-duration: 3s; // Change to Webkit, Mozilla, Opera, etc.
	-vendor-animation-delay: 2s;
	-vendor-animation-iteration-count: infinite;
	animation-duration 3s; // Default
	animation-delay: 2s; // Default
 	animation-iteration-count: infinite; // Default
}

Note: be sure to replace "vendor" in the CSS with the applicable vendor prefixes (webkit, moz, ms, o).

Note: Safari in Mountain Lion (OS X 10.8) has a display glitch with the Flippers. They may not appear at all until the animation is completed, or the page may have other artifacting. One fix is to add overflow: hidden to the parent div.

Build a custom library

Head over to http://daneden.me/animate/build/ to select which animations you need. This will download a .css file, so just rename it to .less and use as described above.

You can also pick & choose which LESS files in your own LESS, just set the variables & import stuff (see animate.less for example):

@animationDurationTime: 0.5s;
@animationDelayTime: 0s;
@animationFillMode: both;
@animationLessLocation: '../node_modules/animate.less/source';

@import "@{animationLessLocation}/animated.less";

@import "@{animationLessLocation}/bounce.less";
@import "@{animationLessLocation}/bounceIn.less";
@import "@{animationLessLocation}/bounceInDown.less";
@import "@{animationLessLocation}/bounceInLeft.less";
@import "@{animationLessLocation}/bounceInRight.less";
@import "@{animationLessLocation}/bounceInUp.less";
@import "@{animationLessLocation}/bounceOut.less";
@import "@{animationLessLocation}/bounceOutDown.less";
@import "@{animationLessLocation}/bounceOutLeft.less";
@import "@{animationLessLocation}/bounceOutRight.less";
@import "@{animationLessLocation}/bounceOutUp.less";

Browser Support

Since we're using CSS3 here, we're limited to only modern browsers like Chrome, Safari, Mozilla, and Opera.

License

Animate.css is licensed under the ☺ license. (http://licence.visualidiot.com/)

Future Development

I'll shortly be compiling an animation-library.less which will allow you to pick and choose which effects you need in your project.

Down the line, IE8/9 support hopefully.
