Understand How Easing Works

See the relationship between a bezier curve and the motion it produces.

Drag the teal & rose handles to shape the curve

transition-timing-function: cubic-bezier(0.25, 0.1, 0.25, 1);

Presets

💡 The rose and teal handles can pull above or below the box (Y beyond 0-1) to create “overshoot” / bounce effects like back-out and anticipate. X stays within 0-1 (time can’t reverse).

Learning tips

📚

The X axis is time, the Y axis is progress. A steep section = fast motion; a flat section = slow motion.

💡

Compare linear (straight diagonal) with ease — watch how the same duration feels completely different.

🎯

The three mini-previews (position, width, scale) show the same curve applied to different properties.
