 *
 * `<Checkbox>` accepts using `<small>` element for ergonomic templating, to
 * redirect the content of `<small>` into `description` when `description` prop
 * was not defined.
 *
 * ```jsx
 * <Checkbox value="check">
 *  <b>Checkbox</b>
 *  <small>
 *    It's a <i>description</i>
 *  </small>
 * </Checkbox>
 * ```
