# CSS: toggle-details

`.instui-toggle-details` — A styled native `<details>` disclosure with a rotating chevron.

Built on the native `<details>` element, so the browser drives open and close plus keyboard support; the CSS only hides the default marker and supplies the rotating chevron.

**Source:** [toggle-details.css](https://github.com/thedannywahl/pantoken/blob/main/formats/components/src/components/toggle-details/toggle-details.css)

## Usage

```css
@import "@pantoken/components/components.css";
@import "@pantoken/components/toggle-details.css";
```

## Examples

```html
<details class="instui-toggle-details" open>
  <summary>What ships in this package?</summary>
  Class-based component styles, built from the Instructure tokens, plus a prose layer.
</details>
```
