# Header

<br />

Headers help drivers understand which app and what part of the app they're
using.
**Can include:**

- Icon or image (optional), such as app icon
- Text (one line only -- longer text is truncated), typically the title of the screen
- [Refresh](https://developers.google.com/cars/design/create-apps/sample-flows/refresh-with-buttons) button (only on Place List templates)
- Back [button](https://developers.google.com/cars/design/create-apps/apps-for-drivers/components/button) (optional)

## Template support

You can use a header in all templates except the
[Navigation template](https://developers.google.com/cars/design/create-apps/apps-for-drivers/templates/navigation-template).
In map-based templates, the header appears in the card. Otherwise, it
incorporates the optional
[action strip](https://developers.google.com/cars/design/create-apps/apps-for-drivers/components/action-strip).

## Guidance

A header must include at least one of the following: text, app icon, or back
button.
