     * Each placement can have a variation from this list:

     * Variations are interpreted easily if you think of them as the left to right

     * is right.<br />
     * Vertically (`left` and `right`), `start` is top and `end` is bottom.
     *
     * Some valid examples are:
     * - `top-end` (on top of reference, right aligned)
     * - `right-start` (on right of reference, top aligned)
     * - `bottom` (on bottom, centered)
     * - `auto-end` (on the side with more space available, alignment depends by placement)

       * Valid examples are:
       * ```
       * 10
