Are the ai2 Glass paginations 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.

Glass paginations

Five frosted pagination shells that vary only the glass surface: a soft frost, a primary tint, a smoky scrim, a clear crystal and a layered depth. Each carries its own page state, is sized, token-driven and marks the active page with aria-current.

PaginationGlass

Installation

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

Run the following command

npx shadcn@latest add @ai2/pagination-glass

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

Install dependencies

npm install motion lucide-react

Copy the source

components/ui/pagination-glass.tsx

"use client"

import * as React from "react"
import { ChevronLeft, ChevronRight, MoreHorizontal } from "lucide-react"

/* Glass pagination family: 5 frosted paginators. They all share the same skeleton;
   the difference is ONLY on the surface of the container (tone, edge, depth). The
   glass is NO LONGER hand-written: every variant derives from the glassDepth scale
   inside @ai2/glass, so the ai2 signature (top inset highlight + ambient shadow) is
   the same language across all variants.

   Choosing the depth (a bar-shaped control): a paginator is wide but SHORT and sits
   in the page flow; behind a short bar a heavy blur brings no gain, so the scale
   starts low and only the genuinely floating variant reaches the top.

   NO GLASS ON GLASS: the glass surface is the BAR itself; the active page is a
   separate highlight on top of it (bg-primary, opaque) - a second glass layer would
   have turned to mud. primary here is not a decorative tint but the semantic role
   of the active/selected state.

   Color comes only from semantic tokens; alpha via color-mix. The active page
   slides with a framer layoutId, and the layoutId derives from React.useId() (there
   are many instances on the same page). */

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.

Frost

A light backdrop-blur shell with a hairline edge.

Tint

A primary-tinted glass shell.

Smoke

A smoky scrim with a medium blur.

Crystal

A very clear shell with a strong blur and a bright top edge.

Depth

A gradient glass shell with a layered shadow.

ai2 Glass paginations: 5 styled variations on the token system

The ai2 Glass paginations are a set of 5 decorative button variations from the styled layer of the @ai2 design system, built around frosted page navigation controls. 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 slides the active highlight between pages. The styled layer is opt-in, so the dependency only lands if you use it; the base components stay lean. Under reduced motion, the highlight jumps to the active page with no animation.

What is in the ai2 Glass paginations?

5 exports in one file: Frost, Tint, Smoke, Crystal and Depth. 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 slides the active highlight between pages.
Reduced-motion aware: Under prefers-reduced-motion, the highlight jumps to the active page with no animation.
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 Glass paginations 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.
