	   * The `offset` modifier can shift your popper on both its axis.

	   * - `px` or unit-less, interpreted as pixels
	   * - `%` or `%r`, percentage relative to the length of the reference element
	   * - `%p`, percentage relative to the length of the popper element
	   * - `vw`, CSS viewport width unit
	   * - `vh`, CSS viewport height unit
	   *
	   * For length is intended the main axis relative to the placement of the popper.<br />
	   * This means that if the placement is `top` or `bottom`, the length will be the
	   * `width`. In case of `left` or `right`, it will be the `height`.
	   *
	   * You can provide a single value (as `Number` or `String`), or a pair of values
	   * as `String` divided by a comma or one (or more) white spaces.<br />
	   * The latter is a deprecated method because it leads to confusion and will be
	   * removed in v2.<br />
	   * Additionally, it accepts additions and subtractions between different units.
	   * Note that multiplications and divisions aren't supported.
	   *
	   * Valid examples are:
	   * ```
	   * 10
	   * '10%'
	   * '10, 10'
	   * '10%, 10'
	   * '10 + 10%'
	   * '10 - 5vh + 3%'
