# ResizeTooltip

ResizeTooltip displays the dimensions of an element whenever the width or height of the element changes.

## Usage

```jsx
const Example = () => {
	return (
		<div style={ { position: 'relative' } }>
			<ResizeTooltip />
			...
		</div>
	);
};
```

Be sure that the parent element containing `<ResizeTooltip />` has the `position` style property defined. This is important as `<ResizeTooltip />` uses `position` based techniques to determine size changes.

### Positions

`<ResizeTooltip />` has three positions;

-   `bottom` (Default)
-   `corner`

##### `bottom`

The `bottom` position (default) renders the dimensions label at the bottom-center of the (parent) element.

##### `corner`

The `corner` position renders the dimensions label in the top-right corner of the (parent) element.
