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:

<Tooltip
    ...
    id={this.props.name}>
    <input type="text"
           ...
           aria-describedby={this.props.name}/>
</Tooltip>

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.
