     wheelDelta
         A number indicating the distance, measured as the number of "clicks" the wheel has been rotated. A positive value indicates that the wheel has been rotated away from the user (or in a right-hand manner on horizontally aligned devices) and a negative value indicates that the wheel has been rotated towards the user (or in a left-hand manner on horizontally aligned devices). The default value of the wheelDelta attribute is 0.
 
-        A "click" is defined to be a unit of rotation. On some devices this is a finite physical step. On devices with smooth rotation, a "click" becomes the smallest measurable amount of rotation.
