forgive my poor english.

Answer 1

you have to use the div position as well as mouse pointer position and fire same effect on mouseenter and mousemove to get the latest position of mouse pointer.

var x,y;

$('.area').on('mouseenter mousemove',function(e){
    //console.log(e.pageX + "|" + e.pageY);
    x= e.pageX;
    y=e.pageY;
    $('.tooltip').css({'top':e.pageY,'left':e.pageX + 15, 'z-index':'1'}).show();
}).on('mouseleave',function(){
    $('.tooltip').hide();
});

Answer 2

$('.area').on('mouseenter',function(){
    $('.tooltip').show();
}).on('mousemove', function(e){
   $('.tooltip').css({'top':e.pageY,'left':e.pageX, 'z-index':'1'});
}).on('mouseleave',function(){
    $('.tooltip').hide();
});

var offset = 10;
setInterval(function(){
    //$('.area').hide();
    $('.area').css({"-webkit-transform":"translate("+offset+"px,"+offset+"px)","-moz-transform":"translate("+offset+"px,"+offset+"px)"});
    //$('.area').css({"left":offset+'px',"top":offset+'px'});
    offset += 10;
},1000);

Check this line "$('.area').css({"-webkit-transform":"translate("+offset+"px,"+offset+"px)","-moz-transform":"translate("+offset+"px,"+offset+"px)"}); //$('.area').css({"left":offset+'px',"top":offset+'px'});" Is that the way you want ? check the fiddle JSFiddle

Answer 3

can you please replace your code with this

and set left and top postion at time of mouseover

$('.area').on('mouseenter',function(){
     $('.tooltip').show();
}).on('mousemove', function(e){
     $('.tooltip').css({'top':e.pageY,'left':e.pageX});
}).on('mouseleave',function(){
     $('.tooltip').hide();
});
