# Localization Provider

A localization provider component for drag-and-drop instructions and screen reader announcements.

## Demo

### Tailwind

This example shows how to implement the component using Tailwind CSS.

```tsx
/* index.tsx */
'use client';
import { Draggable } from '@base-ui/react/draggable';
import { LocalizationProvider } from '@base-ui/react/localization-provider';
import { frFR } from '@base-ui/react/locale-frFR';

const cardKind = Draggable.createKind('card');

export default function LocalizationProviderHero() {
  return (
    <LocalizationProvider translations={frFR}>
      <div
        className="flex min-h-40 select-none flex-col items-center justify-center gap-4 bg-neutral-50 dark:bg-neutral-900"
        lang="fr"
      >
        <Draggable.Root
          className="cursor-grab border border-neutral-950 bg-white px-4 py-2 text-neutral-950 focus-visible:outline-2 focus-visible:-outline-offset-1 data-[drag-preview]:shadow-[0.25rem_0.25rem_0_rgb(0_0_0_/_12%)] dark:border-white dark:bg-neutral-950 dark:text-white dark:data-[drag-preview]:shadow-none"
          kind={cardKind}
          label="la carte"
        >
          Déplacez-moi
          <Draggable.ClonedPreview />
        </Draggable.Root>
        <p className="m-0 text-sm text-neutral-600 dark:text-neutral-400">
          Utilisez Espace et les touches fléchées.
        </p>
      </div>
    </LocalizationProvider>
  );
}
```

### CSS Modules

This example shows how to implement the component using CSS Modules.

```css
/* index.module.css */
.Root {
  display: flex;
  min-height: 10rem;
  flex-direction: column;
  align-items: center;
  justify-content: center;
  gap: 1rem;
  background-color: oklch(98.5% 0 0deg);
  -webkit-user-select: none;
  user-select: none;

  @media (prefers-color-scheme: dark) {
    background-color: oklch(20.5% 0 0deg);
  }
}

.Root,
.Root * {
  font-synthesis: none;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
}

.Card {
  box-sizing: border-box;
  border: 1px solid oklch(14.5% 0 0deg);
  padding: 0.5rem 1rem;
  background: white;
  color: oklch(14.5% 0 0deg);
  cursor: grab;

  &:focus-visible {
    outline: 2px solid currentColor;
    outline-offset: -1px;
  }

  &[data-drag-preview] {
    box-shadow: 0.25rem 0.25rem 0 rgb(0 0 0 / 12%);
  }

  @media (prefers-color-scheme: dark) {
    border-color: white;
    background: oklch(14.5% 0 0deg);
    color: white;
    box-shadow: none;
  }
}

.Hint {
  margin: 0;
  color: oklch(43.9% 0 0deg);
  font-size: 0.875rem;
  line-height: 1.25rem;

  @media (prefers-color-scheme: dark) {
    color: oklch(70.8% 0 0deg);
  }
}
```

```tsx
/* index.tsx */
'use client';
import { Draggable } from '@base-ui/react/draggable';
import { LocalizationProvider } from '@base-ui/react/localization-provider';
import { frFR } from '@base-ui/react/locale-frFR';
import styles from './index.module.css';

const cardKind = Draggable.createKind('card');

export default function LocalizationProviderHero() {
  return (
    <LocalizationProvider translations={frFR}>
      <div className={styles.Root} lang="fr">
        <Draggable.Root className={styles.Card} kind={cardKind} label="la carte">
          Déplacez-moi
          <Draggable.ClonedPreview />
        </Draggable.Root>
        <p className={styles.Hint}>Utilisez Espace et les touches fléchées.</p>
      </div>
    </LocalizationProvider>
  );
}
```

## Anatomy

Import the provider and a locale pack, then wrap the part of your application that should use it:

```jsx title="Anatomy"
import { LocalizationProvider } from '@base-ui/react/localization-provider';
import { frFR } from '@base-ui/react/locale-frFR';

<LocalizationProvider translations={frFR}>
  {/* Your app or a group of components */}
</LocalizationProvider>;
```

Without a provider, Base UI uses the English translations exported from `@base-ui/react/locale-enUS`.

The provider currently translates the accessibility text owned by the drag-and-drop components: the draggable role description, keyboard instructions, handle labels, and live-region announcements. Visible content and consumer-provided labels remain under your control.

## Custom translations

Pass a partial translation object to override only the strings you need. It is usually best to start from a locale pack so the intent stays clear when new translations are added:

```jsx title="Custom translations"
import { LocalizationProvider } from '@base-ui/react/localization-provider';
import { enUS } from '@base-ui/react/locale-enUS';

const translations = {
  ...enUS,
  dragRoleDescription: 'movable',
};

<LocalizationProvider translations={translations}>
  {/* Your drag-and-drop interface */}
</LocalizationProvider>;
```

## Nesting providers

Providers can be nested. An inner provider inherits the outer translations and replaces only the keys it defines:

```jsx title="Nested providers"
<LocalizationProvider translations={frFR}>
  <FrenchBoard />
  <LocalizationProvider translations={{ dragRoleDescription: 'movable' }}>
    <EnglishTerminologyBoard />
  </LocalizationProvider>
</LocalizationProvider>
```

`useTranslations` is an internal hook for Base UI components and is not part of the public package API.
