Frequently Asked Questions
How does cubic-bezier work in CSS?
Cubic-bezier curves define the velocity curve of a transition using four control points between (0,0) and (1,1), dictating acceleration and deceleration over time.
Can Y values exceed 1.0?
Yes! Setting Y1 or Y2 values greater than 1.0 or less than 0.0 creates spring bounce and overshoot animation effects.
