## Usage

Get this component from a [saved library export](/docs/export) or the [connected CLI](/docs/agents). The imports below refer to local files installed in your app.

Import `styles/components.css`, then `styles/theme.css` once. Wrap your app in `ThemeScope` from `components/ui/utils` so typography, focus and overlays share the theme. The [installation guide](/docs/export) covers runtime dependencies and React/Next.js setup.

```tsx
import { Button } from './components/ui/button';

<Button>Continue</Button>
```

## Design system

This component consumes your semantic colors, spacing, typography and shape tokens. Import the compiled styles and your theme once as described in [Export](/docs/export).

## Behavior and accessibility

- Provide meaningful labels for interactive controls.
- Connect action callbacks to your application logic.
- Verify keyboard navigation and contrast in your application.

Status: **experimental** during early access. Sample previews do not send emails, process payments or upload files to a service.

## Source and props

This is the exported source, using the same implementation as the editor.

```tsx
"use client";
import type { ComponentProps } from "react";
import { Button as BaseButton } from "@base-ui/react/button";
import { cx } from "./utils";
export type ButtonProps = Omit<
  ComponentProps<typeof BaseButton>,
  "className"
> & {
  className?: string;
  variant?:
    "primary" | "secondary" | "outline" | "ghost" | "destructive" | "link";
  size?: "sm" | "md" | "lg";
  loading?: boolean;
};
export function Button({
  className,
  variant = "primary",
  size = "md",
  loading = false,
  disabled,
  children,
  ...props
}: ButtonProps) {
  return (
    <BaseButton
      {...props}
      disabled={disabled || loading}
      aria-busy={loading || props["aria-busy"] || undefined}
      className={cx("cr-button", className)}
      data-variant={variant}
      data-size={size}
    >
      {loading && <span className="cr-spinner" aria-hidden="true" />}
      {children}
    </BaseButton>
  );
}
```
