Multiple Choice Questions - Angular 4 Animations

Angular's animation system lets you build animations that run with the same kind of native performance found in pure CSS animations. You can also tightly integrate your animation logic with the rest of your application code, for ease of control.
Angular animations are built on top of the standard Web Animations API and run natively on browsers that support it. [Via]
