Are the ai2 Animated buttons free?

Yes. The whole styled layer is free and MIT licensed, like the component core.

Do they respect reduced motion?

Yes. Under prefers-reduced-motion, the animations stop and the buttons stay still.

Can I change the size?

Yes. Every variation takes a size prop of sm, md, lg or xl, aligned to the base Button height scale.

Animated buttons

Five takes on motion that draws the eye: bounce, scale, slide, rotate and a breathing loop. Each is sized and token-driven.

Manual installs skip the @ai2/tokens theme, so add the token CSS from the theming guide or the tone colors will be missing.

Variations

5 takes on the same idea. Each is its own export, and every one accepts a size prop (sm, md, lg, xl) aligned to the base Button scale.

Bounce

Springs up and settles on hover.

Scale

Grows with a spring on hover.

Slide

A primary surface slides up from the bottom on hover.

Rotate

Tilts slightly on hover.

Breathe

Breathes continuously to pull the eye.

ai2 Animated buttons: 5 styled variations on the token system

The ai2 Animated buttons are a set of 5 decorative button variations from the styled layer of the @ai2 design system, built around motion that draws the eye. They are free and MIT licensed, and every color comes from a semantic token, so they theme with the rest of ai2 in light and dark.

Motion runs on framer-motion: framer-motion springs and loops power the bounce, scale, slide, tilt and breathing effects. The styled layer is opt-in, so the dependency only lands if you use it; the base components stay lean. Under reduced motion, the animations stop and the buttons stay still.

What is in the ai2 Animated buttons?

5 exports in one file: Bounce, Scale, Slide, Rotate and Breathe. Each renders a native button and takes a size prop (sm, md, lg, xl) aligned to the base Button. They are separate from the base Button on purpose: the base keeps its clean variant, tone and size axes, while the styled layer carries the effects.

You own the file. Copy the one category file and you have all 5 variations, with no runtime dependency on ai2 itself.

Why use it

On-system by construction: Every color resolves to an ai2 semantic token, so the buttons follow your theme in light and dark with no extra work.
Effect without the sprawl: The decorations live in a dedicated styled file, so the base Button keeps its clean, predictable API.
Accessible and honest: Each renders a real button element, keeps a visible focus ring, and respects prefers-reduced-motion.

Features

Token-driven color: No hardcoded hex or oklch; the look recolors with your theme tokens.
framer-motion: framer-motion springs and loops power the bounce, scale, slide, tilt and breathing effects.
Reduced-motion aware: Under prefers-reduced-motion, the animations stop and the buttons stay still.
Size aligned to the base: Every variation takes sm, md, lg and xl matching the base Button height scale, so styled and base buttons line up in a row.

Production tips

Use it for emphasis, not everywhere: Styled buttons draw the eye. Reserve them for the one action you want people to take on a screen, and use the base Button for the rest.
Keep labels as verbs: The decoration adds weight, so a clear action label keeps the button scannable.
Pick one variation per surface: The variations share a family; using two different ones in the same view competes for attention.

Works with the rest of ai2

The Animated buttons sit alongside the base Button and the rest of the @ai2 registry. They share the same token file, so a styled action next to a base button or a badge stays visually consistent in both modes.
