    MouseScrollEvent

    Non-standard
    This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

    Deprecated
    This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.

    The MouseScrollEvent interface represents events that occur due to the user moving a mouse wheel or similar input device.

    Do not use this interface for wheel events.

    Like MouseWheelEvent, this interface is non-standard and deprecated. It was used in Gecko-based browsers only. Instead use the standard WheelEvent.
