   $(document).ready(function() {    	
    	var start_in = 0;
    	setInterval(function() {
    	start_in += 226;
    	$(".screenshots-slide-elms ul").each(function () {
    	$(this).css({
    	"transition" : "-webkit-transform 500ms ease 0s",
    	"transform" : "translate3d(-"+start_in+"px, 0px, 0px)",
    	});	
      
      if(start_in>1500)
      {
      start_in = 0;
      $(this).css({
    	"transition" : "-webkit-transform 500ms ease 0s",
    	"transform" : "translate3d(+"+start_in+"px, 0px, 0px)",
    	});	
      }
    	});	
    	},2000);      
    });

           body,html {margin:0; padding:0;}
