Can control points exceed 1.0 to create overshoot bounce effects?

Yes, Y-values can extend beyond 0 and 1 to create elastic snap-back animations.

Are presets like ease-in-quad and ease-out-expo included?

Yes, industry-standard easing presets can be loaded instantly.

1Drag the two control points on the curve coordinator graph.
2Click the preview button to test animation timing against default ease, linear, and ease-in-out.
3Copy the resulting `transition-timing-function: cubic-bezier(...)` CSS.

Standard `ease-in` curves often feel robotic. Custom cubic-bezier timing imparts momentum, weight, and delight to web interactions.

Mathematical Bezier Spline calculation: Precise third-order polynomial curve interpolation.
Elastic Overshoot & Anticipation support: Allows Y coordinates outside [0, 1] for physics-based spring bounce.
Visual Dual-Track Motion Simulator: Directly compares customized easing against constant linear velocity.
Tailwind Arbitrary Syntax generator: Outputs clean, copy-ready [transition-timing-function:cubic-bezier(...)] utility.
