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

**Parallel animations** refers to executing multiple animation steps together. An example of this would be animating an element’s opacity and position at the same time.


# How it works

Defining multiple style changes within the same `style` function would execute our animation in parallel. However, this method doesn’t allow modification to the `animate` function.

Angular animations’ `group` function allows executing multiple independent animations (multiple `animate` functions) in parallel. This grouping mechanism enables us to use different animation configurations for each style change. Each animation could have its duration, delay, and easing, which are then executed together.

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