How it works
Choose a preset or parse

Tune control points
Adjust x1, y1, x2, y2 sliders. Watch the curve graph and moving box preview update.
Copy CSS
Copy transition and animation-timing-function snippets for your stylesheet.

Questions
What does CSS Cubic Bezier do?
It helps you build and preview cubic-bezier easing functions used in CSS transitions and animations.
Why must x1 and x2 stay between 0 and 1?
The CSS cubic-bezier() spec requires control-point x values in that range for timing functions.
Can y values go above 1?
Yes. Y values outside 0–1 create overshoot or bounce-like easing in the preview.
What is the spring preset?
A common custom curve with y1 above 1 that mimics a slight overshoot settle.
