# layout.shell

The frame of an app with a sidebar: one layout.aside beside the main column. Used once, around the signed-in part of the app

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

## Example

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

## Choosing between neighbours

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

| If it is for… | Use |
|---|---|
| The frame of an app with a sidebar: one layout.aside beside the main column. Used once, around the signed-in part of the app | `layout.shell` (this page) |
| A page without a sidebar | [`layout.page`](https://www.prongs.dev/docs/intents/layout/page.md) |
| One page with its own section nav, like settings | [`layout.subnav`](https://www.prongs.dev/docs/intents/layout/subnav.md) |
| The frame of the whole app, around every signed-in page (rather than [`layout.subnav`](https://www.prongs.dev/docs/intents/layout/subnav.md)) | `layout.shell` (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.shell 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.

- [`arrange.sidebar`](https://www.prongs.dev/docs/intents/ui.md#arrange-sidebar) — A fixed-width sidebar column beside a flexible one, stacked on phones

  ```
  grid min-h-dvh md:grid-cols-[15rem_minmax(0,1fr)]
  ```
