CSS Transition Builder
Generate transition CSS with duration, delay, and easing — hover to preview.
About this tool
Generate transition CSS with duration, delay, and easing — hover to preview. Experiment with motion, layout, and color in real time — then copy values into your stylesheet.
Choose the CSS property to transition (opacity, transform, color, …). Set duration, delay, and easing (or a custom cubic-bezier). Example — Opacity hover transition: try `property: opacity, duration: 200ms, timing: ease` and expect something like `transition: opacity 200ms ease 0s;`.
Only animatable properties will interpolate smoothly — display/height quirks still apply. See also: CSS Animation Builder, and Cubic Bezier Generator. Runs in your browser — nothing you paste gets uploaded.
How to use
- Choose the CSS property to transition (opacity, transform, color, …).
- Set duration, delay, and easing (or a custom cubic-bezier).
- Hover the preview to confirm the feel of the transition.
- Copy the transition declaration into your component styles.
Example
Opacity hover transition
Input
property: opacity, duration: 200ms, timing: ease
Output
transition: opacity 200ms ease 0s;
Limitations
- Only animatable properties will interpolate smoothly — display/height quirks still apply.
- Prefers-reduced-motion overrides are not injected automatically.
- Shorthand output may need splitting if you already declare multiple transitions.
