# Banner

> Add a dismissible banner at the top of your documentation site to display important announcements, release notes, or notifications.

Use banners to display important announcements, updates, or notifications across your entire documentation site. Banners appear at the top of every page, support Markdown formatting, and you can make them dismissible. By default, banners use the color defined by the `colors.dark` property in your `docs.json`. You can change the appearance with the `type` property or override the background entirely with `color`.

To add a banner, use the `banner` property in your `docs.json`:

<CodeGroup>
  ```json Product announcements wrap theme={null}
  "banner": {
    "content": "🚀 Version 2.0 is now live! See our [changelog](/changelog) for details.",
    "dismissible": true
  }
  ```

  ```json Maintenance notices wrap theme={null}
  "banner": {
    "content": "⚠️ Scheduled maintenance: API will be unavailable December 15, 2-4 AM UTC",
    "type": "warning",
    "dismissible": false
  }
  ```

  ```json Critical notices wrap theme={null}
  "banner": {
    "content": "**Action required:** Rotate your API keys before January 1. [Migration guide](/migration)",
    "type": "critical",
    "dismissible": true
  }
  ```

  ```json Custom color wrap theme={null}
  "banner": {
    "content": "🎉 Join us at our annual conference!",
    "color": {
      "light": "#7C3AED",
      "dark": "#5B21B6"
    },
    "dismissible": true
  }
  ```
</CodeGroup>

<Note>
  You can also configure banners per language by setting `banner` in `navigation.languages`. See [Language-specific banners](#language-specific-banners).
</Note>

## Properties

<ResponseField name="content" type="string" required>
  The text content displayed in the banner. Supports basic MDX formatting including links, bold, and italic text. Custom components are not supported.
</ResponseField>

<ResponseField name="dismissible" type="boolean">
  Whether users can dismiss the banner. When `true`, a close button appears. If a user closes the banner, it stays hidden for them until you update the banner content. Defaults to `false`.
</ResponseField>

<ResponseField name="type" type="string">
  The visual style of the banner. Controls the background color so visitors can quickly recognize the urgency of the message. Defaults to `info`.

  * `info`: Uses the primary brand color. Best for product announcements and general updates.
  * `warning`: Uses an amber background. Best for cautionary notices like scheduled maintenance or upcoming deprecations.
  * `critical`: Uses a red background. Best for urgent notices that require immediate attention, such as outages or required actions.
</ResponseField>

<ResponseField name="color" type="object">
  Override the banner background color with a custom hex value. When set, this takes precedence over the color implied by `type`. Banner text is white, so choose a background dark enough to remain legible.

  <Expandable title="color properties">
    <ResponseField name="light" type="string">
      Hex color used in light mode. If only `dark` is provided, it's used in light mode as well.
    </ResponseField>

    <ResponseField name="dark" type="string">
      Hex color used in dark mode. If only `light` is provided, it's used in dark mode as well.
    </ResponseField>
  </Expandable>
</ResponseField>

## Language-specific banners

Configure different banner content for each language in your documentation. Define language-specific banners in the `navigation.languages` array in your `docs.json`.

```json theme={null}
{
  "navigation": {
    "languages": [
      {
        "language": "en",
        "banner": {
          "content": "🚀 Version 2.0 is now live! See our [changelog](/en/changelog) for details.",
          "dismissible": true
        },
        "groups": [
          {
            "group": "Getting started",
            "pages": ["en/overview", "en/quickstart"]
          }
        ]
      },
      {
        "language": "es",
        "banner": {
          "content": "🚀 ¡La versión 2.0 ya está disponible! Consulta nuestro [registro de cambios](/es/changelog) para más detalles.",
          "dismissible": true
        },
        "groups": [
          {
            "group": "Getting started",
            "pages": ["es/overview", "es/quickstart"]
          }
        ]
      }
    ]
  },
  "banner": {
    "content": "🚀 Version 2.0 is now live!",
    "dismissible": true
  }
}
```

### Fallback behavior

Banners follow a priority order when determining which content to display:

1. **Language-specific banner**: If the current language has a `banner` configuration, it takes priority.
2. **Global banner**: If no language-specific banner exists, display the global `banner`.
