About this tool: CSS Cubic Bézier Editor
Create a CSS cubic-bezier easing curve, inspect its control points and copy the transition timing function.
The curve begins at (0,0) and ends at (1,1). Both x control values must lie between 0 and 1; y values can extend outside that range to create overshoot. The diagram includes the control handles and a diagonal linear reference. Copy the result into a CSS transition or animation timing property.
How the calculation works
Worked example
| x₁ | 0.25 |
| y₁ | 0.1 |
| x₂ | 0.25 |
| y₂ | 1 |
transition-timing-function: cubic-bezier(0.25, 0.1, 0.25, 1);
