Well-designed animations can make your application more fun and easier to use, but they aren't just cosmetic. Animations can improve your app and user experience in a number of ways: + +* Without animations, web page transitions can seem abrupt and jarring. + +* Motion greatly enhances the user experience, so animations give users a chance to detect the application's response to their actions. + +* Good animations intuitively call the user's attention to where it is needed. + +Typically, animations involve multiple style *transformations* over time.

You can control the timing of each transformation. + +Angular's animation system is built on CSS functionality, which means you can animate any property that the browser considers animatable. This includes positions, sizes, transforms, colors, borders, and more. The W3C maintains a list of animatable properties on its [CSS Transitions](https://www.w3.org/TR/css-transitions-1/) page. + + +## About this guide + +This guide covers the basic Angular animation features to get you started on adding Angular animations to your project. + +The features described in this guide — and the more advanced features described in the related Angular animations guides — are demonstrated in an example app available as a . + +#### Prerequisites + +The guide assumes that you're familiar with building basic Angular apps, as described in the following sections: + +* [Tutorial](tutorial) +* [Architecture Overview](guide/architecture) + + +## Getting started + +The main Angular modules for animations are `@angular/animations` and `@angular/platform-browser`. When you create a new project using the CLI, these dependencies are automatically added to your project. + +To get started with adding Angular animations to your project, import the animation-specific modules along with standard Angular functionality. + +### Step 1: Enabling the animations module + +Import `BrowserAnimationsModule`, which introduces the animation capabilities into your Angular root application module. + + + +
+ +**Note:** When you use the CLI to create your app, the root application module `app.module.ts` is placed in the `src/app` folder. +
+ +### Step 2: Importing animation functions into component files + +If you plan to use specific animation functions in component files, import those functions from `@angular/animations`. + + + + +
+ +**Note:** See a [summary of available animation functions](guide/animations#animation-api-summary) at the end of this guide. +
+ +### Step 3: Adding the animation metadata property + +In the component file, add a metadata property called `animations:` within the `@Component()` decorator. You put the trigger that defines an animation within the `animations` metadata property. + + + + +## Animating a simple transition + +Let's animate a simple transition that changes a single HTML element from one state to another. For example, you can specify that a button displays either **Open** or **Closed** based on the user's last action. When the button is in the `open` state, it's visible and yellow. When it's the `closed` state, it's transparent and green. + +In HTML, these attributes are set using ordinary CSS styles such as color and opacity. In Angular, use the `style()` function to specify a set of CSS styles for use with animations. You can collect a set of styles in an animation state, and give the state a name, such as `open` or `closed`. + +
+ open and closed states +
+ +### Animation state and styles + +Use Angular's `state()` function to define different states to call at the end of each transition. This function takes two arguments: a unique name like `open` or `closed` and a `style()` function. + +Use the `style()` function to define a set of styles to associate with a given state name. Note that the style attributes must be in [*camelCase*](guide/glossary#case-conventions). + +Let's see how Angular's `state()` function works with the `style⁣­(⁠)` function to set CSS style attributes. In this code snippet, multiple style attributes are set at the same time for the state. In the `open` state, the button has a height of 200 pixels, an opacity of 1, and a background color of yellow. + + + + +In the `closed` state, shown below, the button has a height of 100 pixels, an opacity of 0.5, and a background color of green. + + + + +### Transitions and timing + +In Angular, you can set multiple styles without any animation. However, without further refinement, the button instantly transforms with no fade, no shrinkage, or other visible indicator that a change is occurring. + +To make the change less abrupt, we need to define an animation *transition* to specify the changes that occur between one state and another over a period of time. The `transition()` function accepts two arguments: the first argument accepts an expression that defines the direction between two transition states, and the second argument accepts one or a series of `animate()` steps. + + +Use the `animate()` function to define the length, delay, and easing of a transition, and to designate the style function for defining styles while transitions are taking place. You can also use the `animate()` function to define the `keyframes()` function for multi-step animations. These definitions are placed in the second argument of the `animate()` function. + +#### Animation metadata: duration, delay, and easing + +The `animate()` function (second argument of the transition function) accepts the `timings` and `styles` input parameters. + +The `timings` parameter takes a string defined in three parts. + +>`animate ('duration delay easing')` + +The first part, `duration`, is required. The duration can be expressed in milliseconds as a simple number without quotes, or in seconds with quotes and a time specifier. For example, a duration of a tenth of a second can be expressed as follows: + +* As a plain number, in milliseconds: `100` + +* In a string, as milliseconds: `'100ms'` + +* In a string, as seconds: `'0.1s'` + +The second argument, `delay`, has the same syntax as `duration`. For example: + +* Wait for 100ms and then run for 200ms: `'0.2s 100ms'` + +The third argument, `easing`, controls how the animation [accelerates and decelerates](http://easings.net/) during its runtime. For example, `ease-in` causes the animation to begin slowly, and to pick up speed as it progresses. + +* Wait for 100ms, run for 200ms. Use a deceleration curve to start out fast and slowly decelerate to a resting point: `'0.2s 100ms ease-out'` + +* Run for 200ms, with no delay. Use a standard curve to start slow, accelerate in the middle, and then decelerate slowly at the end: `'0.2s ease-in-out'` + +* Start immediately, run for 200ms. Use an acceleration curve to start slow and end at full velocity: `'0.2s ease-in'` + +
+ +**Note:** See the Material Design website's topic on [Natural easing curves](https://material.io/design/motion/speed.html#easing) for general information on easing curves. +
+ +This example provides a state transition from `open` to `closed` with a one second transition between states. + + + + +In the code snippet above, the `=>` operator indicates unidirectional transitions, and `<=>` is bidirectional. Within the transition, `animate()` specifies how long the transition takes. In this case, the state change from `open` to `closed` takes one second, expressed here as `1s`. + +This example adds a state transition from the `closed` state to the `open` state with a 0.5 second transition animation arc. + + + + +
+ +**Note:** Some additional notes on using styles within `state` and `transition` functions. + +* Use `state()` to define styles that are applied at the end of each transition, they persist after the animation has completed. + +* Use `transition()` to define intermediate styles, which create the illusion of motion during the animation. + +* When animations are disabled, `transition()` styles can be skipped, but `state()` styles can't. + +* You can include multiple state pairs within the same `transition()` argument:
`transition( 'on => off, off => void' )`. +
+ +### Triggering the animation + +An animation requires a *trigger*, so that it knows when to start. The `trigger()` function collects the states and transitions, and gives the animation a name, so that you can attach it to the triggering element in the HTML template. + +The `trigger()` function describes the property name to watch for changes. When a change occurs, the trigger initiates the actions included in its definition. These actions can be transitions or other functions, as we'll see later on. + +In this example, we'll name the trigger `openClose`, and attach it to the `button` element. The trigger describes the open and closed states, and the timings for the two transitions. + +
+ triggering the animation +
+ +
+ +**Note:** Within each `trigger()` function call, an element can only be in one state at any given time. However, it's possible for multiple triggers to be active at once. +
+ +### Defining animations and attaching them to the HTML template + +Animations are defined in the metadata of the component that controls the HTML element to be animated. Put the code that defines your animations under the `animations:` property within the `@Component()` decorator. + + + +When you've defined an animation trigger for a component, you can attach it to an element in that component's template by wrapping the trigger name in brackets and preceding it with an `@` symbol. Then, you can bind the trigger to a template expression using standard Angular property binding syntax as shown below, where `triggerName` is the name of the trigger, and `expression` evaluates to a defined animation state. + +``` +
...
; +``` + +The animation is executed or triggered when the expression value changes to a new state. + +The following code snippet binds the trigger to the value of the `isOpen` property. + + + + +In this example, when the `isOpen` expression evaluates to a defined state of `open` or `closed`, it notifies the trigger `openClose` of a state change. Then it's up to the `openClose` code to handle the state change and kick off a state change animation. + +For elements entering or leaving a page (inserted or removed from the DOM), you can make the animations conditional. For example, use `*ngIf` with the animation trigger in the HTML template. + +
+ +**Note:** In the component file, set the trigger that defines the animations as the value of the `animations:` property in the `@Component()` decorator. + +In the HTML template file, use the trigger name to attach the defined animations to the HTML element to be animated. + +

Then, you can bind the trigger to a template expression using standard Angular property binding syntax as shown below, where `triggerName` is the name of the trigger, and `expression` evaluates to a defined animation state. +Cuando hayas definido un disparador de animación para un componente, puedes adjuntarlo a un elemento en la plantilla de ese componente colocando el nombre del disparador entre paréntesis y precediéndolo con un símbolo `@`. Luego, puedes vincular el disparador a una expresión de plantilla utilizando la sintaxis de enlace estándar en Angular como se muestra a continuación, donde `triggerName` es el nombre del disparador, y `expression` evalúa un estado definido de la animación. ```

; ``` -The animation is executed or triggered when the expression value changes to a new state. +La animación se ejecuta o activa cuando el valor de la expresión cambia a un nuevo estado. -The following code snippet binds the trigger to the value of the `isOpen` property. +El siguiente fragmento de código vincula el disparador con el el valor de la propiedad `isOpen`. -In this example, when the `isOpen` expression evaluates to a defined state of `open` or `closed`, it notifies the trigger `openClose` of a state change. Then it's up to the `openClose` code to handle the state change and kick off a state change animation. +En este ejemplo, cuando la expresión `isOpen` evalúa el estado definido de `open` o `closed`, esto notifica al disparador `openClose` de un cambio de estado. Entonces depende del código `openClose` manejar el cambio de estado e iniciar una animación de cambio de estado. -For elements entering or leaving a page (inserted or removed from the DOM), you can make the animations conditional. For example, use `*ngIf` with the animation trigger in the HTML template. +Para los elementos que entran o salen de una página (insertados o eliminados del DOM), puedes hacer que las animaciones sean condicionales. Por ejemplo, usa `*ngIf` con el disparador de animación en la plantilla HTML.
-**Note:** In the component file, set the trigger that defines the animations as the value of the `animations:` property in the `@Component()` decorator. +**Nota:** En el componente, establezca el disparador que define las animaciones como el valor de la propiedad `animations:` en el decorador `@Component ()`. -In the HTML template file, use the trigger name to attach the defined animations to the HTML element to be animated. +En el archivo de la plantilla HTML, usa el nombre del disparador para adjuntar las animaciones definidas al elemento HTML que se va a animar.

-Function name +Nombre de la función -What it does +¿Qué hace?
trigger()Kicks off the animation and serves as a container for all other animation function calls. HTML template binds to triggerName. Use the first argument to declare a unique trigger name. Uses array syntax.Inicia la animación y sirve como contenedor para todas las demás llamadas a funciones de animación. La plantilla HTML se une a triggerName. Utiliza el primer argumento para declarar un nombre de disparador único. Utiliza sintaxis de array.
style()Defines one or more CSS styles to use in animations. Controls the visual appearance of HTML elements during animations. Uses object syntax.Define uno o más estilos CSS para usar en animaciones. Controla la apariencia visual de los elementos HTML durante las animaciones. Utiliza la sintaxis de Object
state()Creates a named set of CSS styles that should be applied on successful transition to a given state. The state can then be referenced by name within other animation functions.Crea un conjunto con nombre de estilos CSS que se deben aplicar en una transición exitosa a un estado dado. A continuación, se puede hacer referencia al estado por su nombre dentro de otras funciones de animación.
animate()Specifies the timing information for a transition. Optional values for delay and easing. Can contain style() calls within.Especifica la información de tiempo para una transición. Valores opcionales para delay y easing. Puede contener llamadas a style() dentro.
transition()Defines the animation sequence between two named states. Uses array syntax.Define la secuencia de animación entre dos estados con nombre. Utiliza sintaxis de array
keyframes()Allows a sequential change between styles within a specified time interval. Use within animate(). Can include multiple style() calls within each keyframe(). Uses array syntax.Permite un cambio secuencial entre estilos dentro de un intervalo de tiempo específico. Usa dentro animate(). Puede incluir dentro múltiples llamadas style() dentro de cada keyframe(). Usa la sintasis de array.
group()Specifies a group of animation steps (inner animations) to be run in parallel. Animation continues only after all inner animation steps have completed. Used within sequence() or transition().Especifica un grupo de animaciones internas de pasos (de animación) que se ejecutarán en paralelo. La animación continúa solo después de que se hayan completado todos los pasos de la animación interna. Usado dentro de sequence() o transition().
query()Use to find one or more inner HTML elements within the current element. Úselo para buscar uno o más elementos HTML internos dentro del elemento actual.
sequence()Specifies a list of animation steps that are run sequentially, one by one.Especifica una lista de pasos de animación que se ejecutan secuencialmente, uno por uno.
stagger()Staggers the starting time for animations for multiple elements.Escalona la hora de inicio de las animaciones de varios elementos.
animation()Produces a reusable animation that can be invoked from elsewhere. Used together with useAnimation().Produce una animación reutilizable que se puede invocar desde otro lugar. Usado junto con useAnimation().
useAnimation()Activates a reusable animation. Used with animation().Activa una animación reutilizable. Usado con animation().
animateChild()Allows animations on child components to be run within the same timeframe as the parent.Permite que las animaciones de los componentes secundarios se ejecuten dentro del mismo período de tiempo que el principal.
