Animations play a crucial role in an application’s user experience (UX). A set of well-designed animations can make an application feel fast, polished, and professional. However, creating animations can be a daunting task that involves knowing what is available and how to choose the right approach for each task.

You will start with the easiest methods and move on to more advanced animation methods as you make your way through this course. You’ll start with general animation techniques, covering CSS transitions, animations, and the Web Animations API, followed by Angular animations and integrating external animation libraries. Lastly, you’ll finish with a deep dive into animation performance and debugging.

This course will provide you with information and advice to help you create beautiful and performant animations in Angular applications. By the end of the course, you will be able to create performant animations and choose the right tools to create them effectively.

How would you animate an element's opacity from `1` to `0.5` with a duration of `0.5` seconds when a state change occurs from `default` to `dimmed` using Angular animations?

How would you animate an element’s opacity from <code>1</code> to <code>0.5</code> with a duration of <code>0.5</code> seconds when a state change occurs from <code>default</code> to <code>dimmed</code> using Angular animations?

The target element fades in, followed by a scale transformation.


The target element fades in and expands in parallel.

The target element expands, followed by a fade in animation.

The target element fades in and slides up.

What is the expected animation output of the code below?

```typescript
trigger("fadeScale", [
    transition(":enter", [
    // set the initial style of the target element
    style({ opacity: 0, transform: "scale(0.5,0.5)" }),
    group([
        // animate the element's opacity for 500ms
        animate(500, style({ opacity: 1 })),
        // animate the element's scale for 600ms with a delay of 300ms
        animate("600ms", style({ transform: "scale(1,1)" })),
    ]),
    ])
]),
```

What is the expected animation output of the code below?
<pre><code class="language-typescript">trigger(&quot;fadeScale&quot;, [
 transition(&quot;:enter&quot;, [
 // set the initial style of the target element
 style({ opacity: 0, transform: &quot;scale(0.5,0.5)&quot; }),
 group([
 // animate the element's opacity for 500ms
 animate(500, style({ opacity: 1 })),
 // animate the element's scale for 600ms with a delay of 300ms
 animate(&quot;600ms&quot;, style({ transform: &quot;scale(1,1)&quot; })),
 ]),
 ])
]),
