CSS value

transition-timing-function: cubic-bezier(0.25, 0.1, 0.25, 1);

Presets

💡 The rose and teal handles can pull above or below the box (Y beyond 0-1) to create “overshoot” / bounce effects like back-out and anticipate. X stays within 0-1 (time can’t reverse).

JS Animation tips

⚙️

Framer Motion accepts an array [x1, y1, x2, y2] — read the four numbers from the cubic-bezier() output.

💡

GSAP's CustomEase and anime.js both take cubic-bezier strings or the four control values.

🎯

Designing the curve visually beats guessing magic numbers — drag until the motion feels right, then copy.
