CSS Animation Performance Best Practices

Performant CSS animations execute without dropping frames (60 FPS) on both mobile and desktop devices.

Animate transform and opacity Only: These properties bypass browser reflow and repaint passes, executing directly on the GPU compositor thread.
Avoid Animating Layout: Avoid animating top, left, width, or margin, which trigger costly CPU browser reflows.
