What is the function of animate?
The animate() method performs a custom animation of a set of CSS properties. This method changes an element from one state to another with CSS styles. The CSS property value is changed gradually, to create an animated effect. Only numeric values can be animated (like "margin:30px").
What is the benefit of Angular animation?
Overall, the angular animation framework allows you to create animations that have the same native performance as pure CSS animations. The benefit is that you can easily add and control animations at the component level.” In addition, the ability to run code before and after animation is a plus.

How do you define a wildcard state in Angular?
Wildcard statelink An asterisk * or wildcard matches any animation state. This is useful for defining transitions that apply regardless of the HTML element's start or end state. For example, a transition of open => * applies when the element's state changes from open to anything else.
How do you define transition between two states in Angular?
Transition basically means navigating from the current state to a new state. In angular, the transition is an animation-specific function which is used in angular's animation DSL language. Transition declares the sequence of animation steps that will be executed when the entered value is satisfied.
What is animation and its uses?
Animation is a method by which still figures are manipulated to appear as moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film. Today, most animations are made with computer-generated imagery (CGI).

What does clicking a button do in a template?
The button element in the template also has a click event bound to it. Clicking the button causes isGreen to toggle values. This changes the component class data. The animation binding picks up on this and invokes its matching trigger (...) method. The trigger (...) lies within the animations array of the component’s metadata. Two things occur upon the trigger’s invocation.
What is the animation binding?
This value determines the resulting color as set by the two style (...) methods inside the trigger (...) block. The animation binding is one-way so that changes to isGreen in the component class notify the template binding. That is, the animation binding toggleClick].
Why is animation important in CSS?
The animatable possibilities are endless thanks to CSS. In a modern web application, animation focuses the user’s attention. Good animations seek to guide the user’s attention in a satisfying, productive manner. Animations should not prove annoying to the user. Animations offer feedback in the form of movement.
What does "animate" mean in animation?
animate (...) initiates an animation while transition (...) determines which animation initiates.
What is the first argument in animation binding?
The first argument matches the value of the data bound to the animation binding. That is, the value bound to selector] in the template matches against first argument of a state (...).

Can you use CSS transitions to animate HTML?
We can use CSS transitions or CSS animations to animate HTML elements. This tutorial will show you both.
What is Angular animation?
Angular animations are based on CSS web transition functionality, so anything that can be styled or transformed in CSS can be animated the same way in Angular. Angular animations allow you to: Set animation timings, styles, keyframes, and transitions. Animate HTML elements in complex sequences and choreographies.
What is animatechild?
Encapsulates a child animation, that can be run explicitly when the parent is run. Instantiated and returned by the animateChild function.
What is the build method in AnimationBuilder?
Provides programmatic control of a reusable animation sequence, built using the build () method of AnimationBuilder. The build () method returns a factory, whose create () method instantiates and initializes this interface.

Angular animations use the native Web Animations API, and as of Angular 6, falls back to CSS keyframes if the Web Animations API is not supported in the user's browser.
What is style in Angular?
The style function is an integral part of Angular animation, a place to specify what styles to apply to the target element at a certain state. An interesting thing about this function is that it accepts 2 types of conventions, which would explain the varying syntax in animation code you would find on the internet - some having camel case and some with dashed case.
How does a keyframe work?
In other words, it lets us sequence our style changes for each element. Since this method can be passed in to the animate function, it can be combined with the previous section’s animation sequences - group, sequence, and stagger, giving us even more control over the sequencing of our animations.

Can Angular do transforms?
This is just scratching the surface of what Angular animations are capable of. Very complex transforms/transitions are possible and can be carefully coordinated in ways that CSS just can’t guarantee.
Setting Up Animations
Animation Methods
- Angular animations use a series of method calls importable from @angular/animations. Each element of the @Componentanimations array begins as a single method. Its arguments unravel as a sequence of higher-order method calls. The following list shows some of the methods used to build Angular animations. 1. trigger(selector: string, AnimationMetadata...
Animation Example
- The above example performs a very simple color swap with each button click. Of course, the color transitions quickly in a linear fade as per animate('1000ms linear'). The animation binds to the button by matching the first argument of trigger(...) to the [@toggleClick]animation binding. The binding binds to the value of isGreen from the component class. This value determines the resul…
Animation State
- The transition(...)micro-syntax is worth addressing in detail. Angular determines animations and their timing by evaluating this syntax. There exists the following state transitions. They model a changes in data bound to an animation binding. 1. ‘someValue’ => ‘anotherValue’ An animation trigger where the bound data changes from ‘someValue’ to ‘anotherValue’. 1. ‘anotherValue’ => ‘s…
Keyframes
- This article touched on the basics for animating Angular applications. Advanced animation techniques exist alongside these basics. Grouping together keyframes is one such technique. Its inspired from the @keyframes CSS rule. If you have worked with CSS @keyframes, you already understand how keyframes in Angular work. It becomes just a matter of syntax The keyframes(..…
Animations with Host Binding
- You will undoubtedly come across the situation where you want to attach an animation to the HTML element of a component itself, instead of an element in the component’s template. This requires a little more effort since you can’t just go into the template HTML and attach the animation there. Instead, you’ll have to import HostBindingand utilize that. The minimal code for …
Conclusion
- This covers the basics of animating with Angular. Angular makes setting up animations very easy using the Angular CLI. Getting started with your first animation only requires a single component class. Remember, animations scope to the component’s template. Export your transitions array from a separate file if you plan to use it across multiple components. Every animation utility/met…
