  * 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 />

  * 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%'
