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.

Animations in Angular

**Sequential animations** refer to executing animations one step at a time. An example of this would be animating an element’s opacity, followed by a rotation animation. Instead of animating both properties together, we can run each animation one at a time. For this particular example, the opacity animation gets executed first. The rotation animation will then wait for the opacity animation to complete before it starts its execution.


# How it works

Angular animations use the `sequence` function to execute sequential animations. It accepts a list of animation steps, which are then executed in the order the steps are sorted in the array.

The `sequence` function accepts two parameters, `steps` and `option`, and returns an `AnimationSequenceMetadata`, an object that encapsulates the sequence data that can be passed to the `transition` function. The code snippet below shows the expected parameters, types, and return type of the `sequence` function.
