Are these CSS animations GPU-accelerated?

Yes. The presets utilize transform and opacity properties (translate3d, scale, rotate) which trigger GPU compositing without reflow or repaint lag.

Can I customize the duration and easing?

Yes. You can adjust the duration in seconds, choose from linear, ease, ease-in, ease-out, ease-in-out, and set infinite or fixed iteration counts.
