## Block Markup

This is a [**hybrid block**](https://developer.wordpress.org/block-editor/getting-started/fundamentals/static-dynamic-rendering/). It saves static markup that the server may enhance during rendering.

```html
<!-- wp:details {"summary":"Details Summary"} -->
<details class="wp-block-details"><summary>Details Summary</summary>
	<!-- wp:paragraph {"placeholder":"Type / to add a hidden block"} -->
	<p>Details Content</p>
	<!-- /wp:paragraph -->
</details>
<!-- /wp:details -->
```
