## Best for

A row of 3 dots that bounce on staggered delays, drawn as plain spans in the primary color, with no icon

## Agent notes

- The dots are bare `span` elements with no status role or label, so screen readers hear nothing; give the wrapper both

## When not to use

- A rotating icon that announces itself to screen readers as loading: use [Basic](https://reui.io/components/spinner/c-spinner-1.md) (`get_example("c-spinner-1")`)

## Install

```bash
npx shadcn@latest add @reui/c-spinner-10
```

## About Shadcn Spinner

### When to use

- Pending states inside buttons, status badges and search fields while a request runs
- Loading views for a card or an empty panel, including blurred covers over content being refreshed
- Inline notes such as checking, syncing or reconnecting, led by a small tinted spinner or bouncing dots

### When not to use

- Content of a known layout, held as muted placeholder shapes until it arrives: use [Skeleton](https://reui.io/components/skeleton.md) (`get_component("skeleton")`)
- A wait where the share of work done is known, such as an upload percent: use [Progress](https://reui.io/components/progress.md) (`get_component("progress")`)
- A save control that tracks its own pending and done states after a click: use [Button](https://reui.io/components/button.md) (`get_component("button")`)

### Agent notes

- No example holds a pending flag and `disabled` is hardcoded where it appears; show the indicator and lock controls from your own request state
