           * `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%'

           * '-10px + 5vh, 5px - 6%'
