# layout.demo

An example app shown inside a page, in its own theme

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.demo">
  …
</Layout>
```

## Choosing between neighbours

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

| If it is for… | Use |
|---|---|
| An example app shown inside a page, in its own theme | `layout.demo` (this page) |
| A framed preview with a title bar | [`layout.window`](https://www.prongs.dev/docs/intents/layout/window.md) |
| The home page demo app (rather than [`layout.example`](https://www.prongs.dev/docs/intents/layout/example.md)) | `layout.demo` (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.

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

## 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.demo 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.
