FAQ
Which CSS properties animate best?
Transform and opacity usually perform best because browsers can animate them without expensive layout recalculation.
Can I copy the generated keyframes?
Yes. Use Copy CSS to export the keyframes and animation declaration.
How should I validate accessibility?
Keep motion purposeful and test reduced-motion alternatives for users who prefer less animation.
