常见问题

›What's a cubic-bezier?

A curve defined by 4 control values — used by CSS transitions and animations to control the rate of change over time. The browser's 'ease' is cubic-bezier(0.25, 0.1, 0.25, 1).

›What's overshoot?

When the easing curve exceeds 0 or 1 (control y-values < 0 or > 1), the animation 'bounces' past its endpoints. Useful for playful UIs.

›Are presets available?

Yes — common presets (linear, ease, ease-in, ease-out, ease-in-out) plus a few popular custom curves.

›Is the editor free?

Yes — fully free, no signup.
