* @description
*
* # ngAnimate
*
* The `ngAnimate` module provides support for JavaScript, CSS3 transition and CSS3 keyframe animation hooks within existing core and custom directives.
*
* {@installModule animate}
*
* <div doc-module-components="ngAnimate"></div>
*
* # Usage
*
* To see animations in action, all that is required is to define the appropriate CSS classes
* or to register a JavaScript animation via the myModule.animation() function. The directives that support animation automatically are:
* `ngRepeat`, `ngInclude`, `ngIf`, `ngSwitch`, `ngShow`, `ngHide`, `ngView` and `ngClass`. Custom directives can take advantage of animation
* by using the `$animate` service.
*
* Below is a more detailed breakdown of the supported animation events provided by pre-existing ng directives:
*
* | Directive | Supported Animations |
* |---------------------------------------------------------- |----------------------------------------------------|
* | {@link ng.directive:ngRepeat#usage_animations ngRepeat} | enter, leave and move |
* | {@link ngRoute.directive:ngView#usage_animations ngView} | enter and leave |
* | {@link ng.directive:ngInclude#usage_animations ngInclude} | enter and leave |
* | {@link ng.directive:ngSwitch#usage_animations ngSwitch} | enter and leave |
* | {@link ng.directive:ngIf#usage_animations ngIf} | enter and leave |
* | {@link ng.directive:ngClass#usage_animations ngClass} | add and remove |
* | {@link ng.directive:ngShow#usage_animations ngShow & ngHide} | add and remove (the ng-hide class value) |
*
* You can find out more information about animations upon visiting each directive page.
*
* Below is an example of how to apply animations to a directive that supports animation hooks:
*
* <pre>
* <style type="text/css">
* .slide.ng-enter, .slide.ng-leave {
* -webkit-transition:0.5s linear all;
* transition:0.5s linear all;
* }
*
* .slide.ng-enter { } /* starting animations for enter */
* .slide.ng-enter-active { } /* terminal animations for enter */
* .slide.ng-leave { } /* starting animations for leave */
* .slide.ng-leave-active { } /* terminal animations for leave */
* </style>
*
* <!--
* the animate service will automatically add .ng-enter and .ng-leave to the element
* to trigger the CSS transition/animations
* -->
* <ANY class="slide" ng-include="..."></ANY>
* </pre>
*
* Keep in mind that if an animation is running, any child elements cannot be animated until the parent element's
* animation has completed.
*
* <h2>CSS-defined Animations</h2>
* The animate service will automatically apply two CSS classes to the animated element and these two CSS classes
* are designed to contain the start and end CSS styling. Both CSS transitions and keyframe animations are supported
* and can be used to play along with this naming structure.
*
* The following code below demonstrates how to perform animations using **CSS transitions** with Angular:
*
* <pre>
* <style type="text/css">
* /*
* The animate class is apart of the element and the ng-enter class
* is attached to the element once the enter animation event is triggered
* */
* .reveal-animation.ng-enter {
* -webkit-transition: 1s linear all; /* Safari/Chrome */
* transition: 1s linear all; /* All other modern browsers and IE10+ */
*
* /* The animation preparation code */
* opacity: 0;
* }
*
* /*
* Keep in mind that you want to combine both CSS
* classes together to avoid any CSS-specificity
* conflicts
* */
* .reveal-animation.ng-enter.ng-enter-active {
* /* The animation code itself */
* opacity: 1;
* }
* </style>
*
* <div class="view-container">
* <div ng-view class="reveal-animation"></div>
* </div>
* </pre>
*
* The following code below demonstrates how to perform animations using **CSS animations** with Angular:
*
* <pre>
* <style type="text/css">
* .reveal-animation.ng-enter {
* -webkit-animation: enter_sequence 1s linear; /* Safari/Chrome */
* animation: enter_sequence 1s linear; /* IE10+ and Future Browsers */
* }
* @-webkit-keyframes enter_sequence {
* from { opacity:0; }
* to { opacity:1; }
* }
* @keyframes enter_sequence {
* from { opacity:0; }
* to { opacity:1; }
* }
* </style>
*
* <div class="view-container">
* <div ng-view class="reveal-animation"></div>
* </div>
* </pre>
*
* Both CSS3 animations and transitions can be used together and the animate service will figure out the correct duration and delay timing.
*
* Upon DOM mutation, the event class is added first (something like `ng-enter`), then the browser prepares itself to add
* the active class (in this case `ng-enter-active`) which then triggers the animation. The animation module will automatically
* detect the CSS code to determine when the animation ends. Once the animation is over then both CSS classes will be
* removed from the DOM. If a browser does not support CSS transitions or CSS animations then the animation will start and end
* immediately resulting in a DOM element that is at its final state. This final state is when the DOM element
* has no CSS transition/animation classes applied to it.
*
* <h3>CSS Staggering Animations</h3>
* A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a
* curtain-like effect. The ngAnimate module, as of 1.2.0, supports staggering animations and the stagger effect can be
* performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for
* the animation. The style property expected within the stagger class can either be a **transition-delay** or an
* **animation-delay** property (or both if your animation contains both transitions and keyframe animations).
*
* <pre>
* .my-animation.ng-enter {
* /* standard transition code */
* -webkit-transition: 1s linear all;
* transition: 1s linear all;
* opacity:0;
* }
* .my-animation.ng-enter-stagger {
* /* this will have a 100ms delay between each successive leave animation */
* -webkit-transition-delay: 0.1s;
* transition-delay: 0.1s;
*
* /* in case the stagger doesn't work then these two values
* must be set to 0 to avoid an accidental CSS inheritance */
* -webkit-transition-duration: 0s;
* transition-duration: 0s;
* }
* .my-animation.ng-enter.ng-enter-active {
* /* standard transition styles */
* opacity:1;
* }
* </pre>
*
* Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations
* on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this
* are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation
* will also be reset if more than 10ms has passed after the last animation has been fired.
*
* The following code will issue the **ng-leave-stagger** event on the element provided:
*
* <pre>
* var kids = parent.children();
*
* $animate.leave(kids[0]); //stagger index=0
* $animate.leave(kids[1]); //stagger index=1
* $animate.leave(kids[2]); //stagger index=2
* $animate.leave(kids[3]); //stagger index=3
* $animate.leave(kids[4]); //stagger index=4
*
* $timeout(function() {
* //stagger has reset itself
* $animate.leave(kids[5]); //stagger index=0
* $animate.leave(kids[6]); //stagger index=1
* }, 100, false);
* </pre>
*
* Stagger animations are currently only supported within CSS-defined animations.
*
* <h2>JavaScript-defined Animations</h2>
* In the event that you do not want to use CSS3 transitions or CSS3 animations or if you wish to offer animations on browsers that do not
* yet support CSS transitions/animations, then you can make use of JavaScript animations defined inside of your AngularJS module.
*
* <pre>
* //!annotate="YourApp" Your AngularJS Module|Replace this or ngModule with the module that you used to define your application.
* var ngModule = angular.module('YourApp', ['ngAnimate']);
* ngModule.animation('.my-crazy-animation', function() {
* return {
* enter: function(element, done) {
* //run the animation here and call done when the animation is complete
* return function(cancelled) {
* //this (optional) function will be called when the animation
* //completes or when the animation is cancelled (the cancelled
* //flag will be set to true if cancelled).
* };
* },
* leave: function(element, done) { },
* move: function(element, done) { },
*
* //animation that can be triggered before the class is added
* beforeAddClass: function(element, className, done) { },
*
* //animation that can be triggered after the class is added
* addClass: function(element, className, done) { },
*
* //animation that can be triggered before the class is removed
* beforeRemoveClass: function(element, className, done) { },
*
* //animation that can be triggered after the class is removed
* removeClass: function(element, className, done) { }
* };
* });
* </pre>
*
* JavaScript-defined animations are created with a CSS-like class selector and a collection of events which are set to run
* a javascript callback function. When an animation is triggered, $animate will look for a matching animation which fits
* the element's CSS class attribute value and then run the matching animation event function (if found).
* In other words, if the CSS classes present on the animated element match any of the JavaScript animations then the callback function will
* be executed. It should be also noted that only simple, single class selectors are allowed (compound class selectors are not supported).
*
* Within a JavaScript animation, an object containing various event callback animation functions is expected to be returned.
* As explained above, these callbacks are triggered based on the animation event. Therefore if an enter animation is run,
* and the JavaScript animation is found, then the enter callback will handle that animation (in addition to the CSS keyframe animation
* or transition code that is defined via a stylesheet).
*
