# layout.header

The site header at the top of every page: the site name and its navigation

Component: [`<Layout>`](https://www.prongs.dev/docs/components/layout.md) · Renders: `<header>` · Profile: [UI](https://www.prongs.dev/docs/intents/ui.md)

## Example

```tsx
<Layout intent="layout.header">
  …
</Layout>
```

## Choosing between neighbours

Find the row that describes your element, and use the intent on the right.

| If it is for… | Use |
|---|---|
| The site header at the top of every page: the site name and its navigation | `layout.header` (this page) |
| The top of a section inside a page | [`layout.section`](https://www.prongs.dev/docs/intents/layout/section.md) |

## Connections

Declared in the registry, both directions. Where an intent is used in your own code is something check and the gallery see; this site has no app code.

- Built from: [`constraint.wide`](https://www.prongs.dev/docs/intents/ui.md#constraint-wide), [`arrange.row`](https://www.prongs.dev/docs/intents/ui.md#arrange-row)

## For registry authors

**Starter intents.** These are the intents `prongs add` puts in your registry, shown in this site’s theme. Yours are your own `registry.ts`: rename, restyle and add to them, and see them with `prongs add gallery`.

What this intent is built from and its entry in `components/prongs/registry.ts`. You only need this to change how it looks or to add an intent like it.

How layout.header resolves, and its definition

Each layer adds to the one before it; a later class wins over an earlier one that sets the same thing.

- [`constraint.wide`](https://www.prongs.dev/docs/intents/ui.md#constraint-wide) — Centred, wide content width

  ```
  mx-auto w-full max-w-6xl px-4 sm:px-6
  ```

- [`arrange.row`](https://www.prongs.dev/docs/intents/ui.md#arrange-row) — Children in a wrapping row

  ```
  flex flex-row flex-wrap items-center
  ```

- `layout.header` (this page) — The site header at the top of every page: the site name and its navigation

  ```
  justify-between gap-4 py-4
  ```

Final classes

```
mx-auto w-full max-w-6xl px-4 sm:px-6 flex flex-row flex-wrap
items-center justify-between gap-4 py-4
```
