    .map((val, i) => (
      <Elevation z={i} key={i}>
        {i}dp
      </Elevation>
    ))}
</>

function Example() {
  const [elevation, setElevation] = React.useState(0);

  return (
    <Elevation
      z={elevation}
      transition
      onMouseOver={() => setElevation(24)}
      onMouseOut={() => setElevation(0)}
    >
      Hover Me {elevation}dp
    </Elevation>
  );
}

Wrapping Children

You can avoid adding extra DOM nodes by using the wrap prop on elevation. This will apply the classes directly to the child component. Additionally, Elevation is simply a className, so you can achieve the same effect by adding className="mdc-elevation--z15".

<Elevation z={21} wrap>
  <span>Wrapped!</span>
</Elevation>
