# Tooltip

<Preview>
<button class="btn" data-variant="outline" data-tooltip="Add to library">Hover</button>
</Preview>

## Usage

Add `data-tooltip` to the trigger element. Use `data-side` and `data-align` to change the position:

- `data-tooltip`: Tooltip text.
- `data-side` `Optional`: `top`, `bottom`, `left`, `right`, `inline-start`, or `inline-end`. Defaults to `top`.
- `data-align` `Optional`: `start`, `center`, or `end`. Defaults to `center`.

Basecoat tooltips are CSS-only and text-only. This intentionally differs from shadcn/ui's composed tooltip content, which can render arbitrary markup and uses a portal.

```html
<button class="btn" data-variant="outline" data-tooltip="Tooltip text" data-side="bottom" data-align="center">Bottom</button>
```
