# layout.page

The main column of an app page, used once per page

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

## Example

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

## Choosing between neighbours

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

| If it is for… | Use |
|---|---|
| The main column of an app page, used once per page | `layout.page` (this page) |
| Text-heavy pages | [`layout.article`](https://www.prongs.dev/docs/intents/layout/article.md) |
| A page for one short task like signing in | [`layout.task`](https://www.prongs.dev/docs/intents/layout/task.md) |
| A page without a sidebar (rather than [`layout.shell`](https://www.prongs.dev/docs/intents/layout/shell.md)) | `layout.page` (this page) |
| An app page (rather than [`layout.marketing`](https://www.prongs.dev/docs/intents/layout/marketing.md)) | `layout.page` (this page) |

## 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.

## 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.page 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.stack`](https://www.prongs.dev/docs/intents/ui.md#arrange-stack) — Children in a column, free to shrink inside a row or grid

  ```
  flex min-w-0 flex-col
  ```

- `layout.page` (this page) — The main column of an app page, used once per page

  ```
  gap-[clamp(2rem,6vw,2.5rem)] py-[clamp(2rem,6vw,2.5rem)]
  ```

Final classes

```
mx-auto w-full max-w-6xl px-4 sm:px-6 flex min-w-0 flex-col
gap-[clamp(2rem,6vw,2.5rem)] py-[clamp(2rem,6vw,2.5rem)]
```
