What's the difference between CSS animation and transition?

Transition interpolates between two states triggered by a state change. Animation can auto-play without a trigger and supports multiple keyframes for complex motions.

Do animations affect performance?

Animating transform and opacity uses GPU acceleration and is highly performant. Avoid animating width, height, or margin as they trigger layout reflows.
