What it does
- Six holes based on real easing curves, including overshoot and anticipation
- Drag the handles with touch, mouse or arrow keys
- Missed putts reveal the target points, so every stroke teaches
- Shareable scorecard with birdies and bogeys
FAQ
What is a cubic-bezier easing curve?
It maps animation time to progress with two control points. CSS writes it as cubic-bezier(x1, y1, x2, y2); values above 1 or below 0 on the y axis create overshoot and anticipation.
How do I get better at reading curves?
A steep start means fast early movement (ease out), a flat start means a slow start (ease in). Practice in the Motion Playground, then come back for a lower score.
