#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.less is 60kb and animate.min.less is 48kb.

bootstrap.less is a straightforward example of how to implement this library with your Bootstrap project.

animate.css is 61kb and is an original copy by Dan Eden.

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

@import "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, 2) extend the delay, or 3) 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.

##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.
