CSS Transition Generator

Build a multi-property transition value and watch it play on real hover -- configurable end-state (scale, rotate, move, fade, colour, radius), multiple transition layers with independent duration/easing/delay, presets, randomize, and export to CSS, Tailwind, SCSS or React.

What this tool does

Builds a transition value from one or more independently-timed layers, paired with a configurable hover end-state, and plays it on a real hoverable box so the timing and easing can be judged by feel rather than only read as numbers.

Multiple transition layers

Each layer targets one CSS property (or all) with its own duration, easing curve, and delay — staggering when a colour change starts relative to a transform, for example, rather than every property having to move in perfect lockstep. Layers can be added or removed freely.

Configurable hover end-state

Scale, rotation, X/Y translation, opacity, border-radius, and background colour on hover are all independently adjustable — covering the actual visual change a transition reveals, not just the timing function applied to it.

A real hover demo, not just a code preview

The preview box actually responds to being hovered with the exact transition and end-state configured, so the feel of a duration or easing curve — snappy versus bouncy versus smooth — can be tested directly instead of imagined from a number.

Presets and randomizing

Five presets — Smooth Scale, Colour Swap, Slide Fade, Bouncy (with an overshooting cubic-bezier), and Snappy (a fast linear transition) — cover common feels, plus a randomize button for quick exploration.

Getting the CSS out

Export as plain CSS (base + :hover rules), a Tailwind class string (including hover: variants), SCSS, or React style objects with a note on toggling hover state, copyable with one click.

FAQ

Frequently asked questions

Is my data uploaded anywhere?
No. The transition is built and demonstrated entirely in the browser -- nothing is sent to a server.
Can I actually feel the timing, not just read the numbers?
Yes -- the preview box is a real hoverable element with the exact transition and end-state applied, so hovering it plays the actual animation rather than only showing generated code.
Why would I need more than one transition layer?
Different properties often want different timing -- a colour change finishing quickly while a transform eases in more slowly, for example. Multiple layers let each property have its own duration, easing, and delay instead of forcing every property to share one timing function.
What does the Bouncy preset use for its easing?
An overshooting cubic-bezier() curve that goes slightly past 100% before settling, producing a springy bounce rather than a smooth ease.
What hover end-state properties can be changed?
Scale, rotation, X/Y translation, opacity, border-radius, and background colour -- covering the actual visual change alongside the timing.
What export formats are available?
Plain CSS with base and :hover rules, a Tailwind class string including hover: variants, SCSS, or React style objects with a note on toggling hover state via a class -- selectable from a dropdown next to the code output.
