Easing for @keyframes Animations

Pick the right animation-timing-function for CSS keyframe animations.

Drag the teal & rose handles to shape the curve

Width transition
CSS value
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).

Keyframes tips

🎬

animation-timing-function accepts cubic-bezier() too — copy the value into your @keyframes animation shorthand.

💡

Note: the timing function applies between each keyframe pair, not across the whole animation.

🎯

For looping animations, ease-in-out style curves avoid the jarring stop-start of linear.
