# Source: dnd-indicator.js

    /*
     * code review by Pavel Yaschenko
     *
     * 1. No need to save DOM element (this.indicator). We can use id to get dom element. It helps to avoid memory leaks :)
     *
     * 2. Name refactoring: change names acceptClass, rejectClass, draggingClass
     * 						to more readable names: getAcceptClass, getRejectClass, getDragClass
     *
     */
