$(document).ready(function() {

        var nice = false;
          $(function() {  

              nice = $('body').niceScroll({
                cursorcolor: "#00a351", // change cursor color in hex
                cursoropacitymin: 0, // change opacity when cursor is inactive (scrollabar "hidden" state), range from 1 to 0
                cursoropacitymax: 1, // change opacity when cursor is active (scrollabar "visible" state), range from 1 to 0
                cursorwidth: "8px", // cursor width in pixel (you can also write "5px")
                cursorborder: "0px solid #fff", // css definition for cursor border
                cursorborderradius: "0px",
                autohidemode: false,
                railalign: "right",
                railpadding: { top: 0, right: 0, left: 0, bottom: 0 },
                emulatetouch: false,
