## Important Note
`Tooltip` requires a child node that accepts an `onMouseEnter`, `onMouseLeave`, `onFocus`, `onClick` event. This means the child node must be a built-in component like `div` or `span`, or a custom component that passes its props to its built-in component child.
## Accessibility
For accessibility purpose you can use the `id` prop to link your tooltip with another element. For example attaching it to an input element:
```js
```
If you do it like this, a screenreader would read the content of your tooltip if you focus the input element.
**NOTE:** `role="tooltip"` is also added to expose the purpose of the tooltip element to a screenreader.
