Frequently Asked Questions

What is a cubic-bezier timing function?
A cubic-bezier timing function defines a transition speed curve using four coordinate control points (x1, y1, x2, y2) of a cubic Bezier curve, defining custom ease animations.
What do the four parameters of cubic-bezier represent?
The parameters represent two control points: P1 (x1, y1) and P2 (x2, y2). X values represent time (0 to 1), and Y values represent animation progress.
How do I create bounce transitions using cubic-bezier?
Set the Y coordinate values (y1 or y2) beyond the 0 to 1 range (like 1.5 or -0.5). This causes the element to overshoot and bounce back.
What is the difference between ease-in and ease-out timing curves?
Ease-in starts slow and accelerates at the end. Ease-out starts fast and decelerates at the end. Custom curves can combine these effects.
How do I test my custom transition curve in real-time?
The calculator includes an animation test area. Click 'Run Animation Test' to watch boxes slide across the screen using your custom ease vs linear.
Are cubic-bezier curves supported in all browsers?
Yes, cubic-bezier timing functions are supported in all modern web browsers under transition-timing-function and animation-timing-function rules.
Can X values in cubic-bezier exceed the 0 to 1 range?
No, X values represent time segments and must be between 0 and 1. Y values can exceed this range to create bounce actions.
Is this Bezier tool free to use?
Yes, the cubic-bezier visualizer is 100% free with no registration or limits.
Does this tool work offline?
Yes, the entire animation and rendering math is loaded in your browser and works completely offline.
Is my transition data secure?
Yes, all coordinate calculations are handled locally. No data is stored or logged.
