In this article Michelle Barker will t

There are way too many options in Web Animations API to pick them up that easily. There’s no middle ground between simple transitions and complex animations. You’re either fine with what CSS Transitions and Animations provide or you suddenly need all the power you can get. Learning how timing works and how to control the playback of several animations at once makes for a solid foundation on which
