The event that prevents a long press copy is mainly composed of two parts;

1.js aspect:

1     function (e) {E.preventdefault ();};

2.css aspect:

 *  {margin : ; padding : 0 ; -webkit-touch-callout : none ; -webkit-touch-callout : none ; -webkit-user-select : none ; -khtml-user-select : none ; -moz-user-select : none ; -ms-user-select : none ;         User-select : none ; }
