This means that any active transition animations operating on the element + * will be cut off to make way for the enter, leave or move animation. + * + * ### Class-based transition animations + * + * Class-based transitions refer to transition animations that are triggered when a CSS class is + * added to or removed from the element (via `$animate.addClass`, `$animate.removeClass`, + * `$animate.setClass`, or by directives such as `ngClass`, `ngModel` and `form`). + * They are different when compared to structural animations since they **do not cancel existing + * animations** nor do they **block successive transitions** from rendering on the same element. + * This distinction allows for **multiple class-based transitions** to be performed on the same element. + * + * In addition to ngAnimate supporting the default (natural) functionality of class-based transition + * animations, ngAnimate also decorates the element with starting and ending CSS classes to aid the + * developer in further styling the element throughout the transition animation. Earlier versions + * of ngAnimate may have caused natural CSS transitions to break and not render properly due to + * $animate temporarily blocking transitions using `0s none` in order to allow the setup CSS class + * (the `-add` or `-remove` class) to be applied without triggering an animation. However, as of + * **version 1.3**, this workaround has been removed with ngAnimate and all non-ngAnimate CSS + * class transitions are compatible with ngAnimate. + * + * There is, however, one special case when dealing with class-based transitions in ngAnimate. + * When rendering class-based transitions that make use of the setup and active CSS classes + * (e.g. `.fade-add` and `.fade-add-active` for when `.fade` is added) be sure to define + * the transition value **on the active CSS class** and not the setup class. + * + * ```css + * .fade-add { + * /&#42; remember to place a 0s transition here + * to ensure that the styles are applied instantly + * even if the element already has a transition style &#42;/ + * transition:0s linear all; + * + * /&#42; starting CSS styles &#42;/ + * opacity:1; + * } + * .fade-add.fade-add-active { + * /&#42; this will be the length of the animation &#42;/ + * transition:1s linear all; + * opacity:0; + * } + * ``` + * + * The setup CSS class (in this case `.fade-add`) also has a transition style property, however, it + * has a duration of zero. This may not be required, however, incase the browser is unable to render + * the styling present in this CSS class instantly then it could be that the browser is attempting + * to perform an unnecessary transition. + * + * This workaround, however, does not apply to standard class-based transitions that are rendered + * when a CSS class containing a transition is applied to an element: + * + * ```css + * .fade { + * /&#42; this works as expected &#42;/ + * transition:1s linear all; + * opacity:0; + * } + * ``` + * + * Please keep this in mind when coding the CSS markup that will be used within class-based transitions. + * Also, try not to mix the two class-based animation flavors together since the CSS code may become + * overly complex. + * + * ### CSS Staggering Animations * 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.
