Are the ai2 Layout hover cards free?

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

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.

Layout hover cards

Five hover cards that keep one open mechanism and change only the inner arrangement: a horizontal avatar row, a compact dense line, a wide two-column card, a vertical stack with a stat row and a split card with a separated action bar. Each is self-contained (no radix), sized, token-driven, and opens on hover or keyboard focus.

Hover cardLayout

Installation

The styled layer is free and installs like any other ai2 component.

Run the following command

npx shadcn@latest add @ai2/hover-card-layout

Dependencies, the @ai2/tokens theme and the component file are installed together.

Install dependencies

npm install motion lucide-react

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.

Horizontal

An avatar on the left with the text on the right.

Compact

A small, dense single row for a quick label.

Wide

A wide card split into two readable columns.

Stacked

A vertical stack: title, description and a stat row.

Split

Top content with a separated action bar below.

ai2 Layout hover cards: 5 styled variations on the token system

The ai2 Layout hover cards are a set of 5 decorative button variations from the styled layer of the @ai2 design system, built around inner content layouts on a hover-opened card. 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: the cards fade and rise on token CSS transitions when the trigger is hovered or focused. The styled layer is opt-in, so the dependency only lands if you use it; the base components stay lean. Under reduced motion, the transitions and transform are skipped and the card appears instantly.

What is in the ai2 Layout hover cards?

5 exports in one file: Horizontal, Compact, Wide, Stacked and Split. 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: the cards fade and rise on token CSS transitions when the trigger is hovered or focused.
Reduced-motion aware: Under prefers-reduced-motion, the transitions and transform are skipped and the card appears instantly.
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 Layout hover cards 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.
