Installation

npx logic2b@next add card

Working with an AI assistant? Copy this prompt into Claude Code, Cursor or Copilot — it carries the install steps, a no-CLI fallback and a verification checklist.

Add the "card" item from the logic2b ui registry (https://ui.logic2b.com) to this project. Follow every step and verify at the end.

## Steps

1. If the project has no `components.json` yet, set up logic2b ui first:

   ```bash
   npx logic2b@next init
   ```

2. Install the item (the CLI resolves registry dependencies automatically):

   ```bash
   npx logic2b@next add card
   ```

3. Install any npm dependencies the command prints.

## If the CLI is not available

Do it manually from the registry payload:

1. Fetch https://ui.logic2b.com/r/card.json.
2. Write every entry in `files[]` to its mapped project path (see below).
3. Repeat (recursively) for each name in `registryDependencies`.
4. Install every package listed in `dependencies` across those payloads.

## Registry reference

- Index of every item: https://ui.logic2b.com/r/index.json
- Item payload (full source): https://ui.logic2b.com/r/<name>.json
- Usage examples per item: https://ui.logic2b.com/r/demos/index.json → https://ui.logic2b.com/r/demos/<demo>.json
- Docs index for agents: https://ui.logic2b.com/llms.txt (full docs: https://ui.logic2b.com/llms-full.txt)
- Every docs page is Markdown when you append `.md` to its URL.

Registry file paths map to project paths like this:
- `ui/*` → `@/components/ui/*`
- `blocks/<name>/*` → `@/components/*`
- `charts/*` → `@/components/charts/*`
- `hooks/*` → `@/hooks/*`
- `lib/utils.ts` → `@/lib/utils.ts`
- `theme.css` → next to the project's Tailwind entry stylesheet

## Conventions (do not break these)

- Tailwind CSS v4 (CSS-first config; no tailwind.config.js needed) and React 19.
- All colors go through semantic tokens (`bg-primary`, `text-muted-foreground`,
  `border-border`, …). Never hardcode hex/oklch values in components.
- Dark mode is class-based: toggle `.dark` on `<html>`.
- Icons come from lucide-react.

## Verify before finishing

1. The dev server starts and the app renders without console errors.
2. TypeScript compiles (`tsc --noEmit` or the framework's check).
3. Components use the theme: a `<Button>` shows the primary token color,
   and toggling `.dark` on `<html>` switches the palette.

Copy into ui/card.tsx:

import * as React from "react"

import { cn } from "@/lib/utils"

function Card({ className, ...props }: React.ComponentProps<"div">) {
  return (
    <div
      data-slot="card"

      {...props}
    />
  )
}

function CardHeader({ className, ...props }: React.ComponentProps<"div">) {
  return (
    <div
      data-slot="card-header"
      className={cn(

        className
      )}
      {...props}

    <div
      data-slot="card-content"
      className={cn("px-6", className)}

      className={cn("flex items-center px-6 [.border-t]:pt-6", className)}
      {...props}

export {

}

Usage

import {
  Card,
  CardAction,
  CardContent,
  CardDescription,
  CardFooter,
  CardHeader,
  CardTitle,
} from "@/components/ui/card"

<Card>
  <CardHeader>
    <CardTitle>Title</CardTitle>
    <CardDescription>Description</CardDescription>
    <CardAction>{/* e.g. a button, top-right */}</CardAction>
  </CardHeader>
  <CardContent>Content</CardContent>
  <CardFooter>Footer</CardFooter>
</Card>

Usage notes

Card is composed of layout primitives — Card, CardHeader, CardTitle, CardDescription, CardAction, CardContent, and CardFooter. Each is a styled div that accepts className plus the standard div props; there are no variant props. CardAction is positioned in the top-right of the header, and CardHeader switches to a two-column grid when a CardAction is present.

Examples

With action

Place a control such as a badge or button in the header via CardAction.
