So this is what I got.

 <div class="box"></div>

---

 .box {
 position: absolute;
 left: 0;
 top: 0;
 width: 100px;
 height: 100px;
 background: yellow;
 }

---

 $(document).bind('mousemove', function(e){
 $('.box').css({
 top: e.pageY
 left:  e.pageX,
 });
 });

It works. The box follow the cursor. Problem is it follow the EDGE of the cursor. ie, the cursor holds the top left corner of the box. I want it to hold the center of the box, or another point that's not the edge. Any ideas how to do that?

Sorry if this dumb. I'm good enough with HTML/CSS but just starting with javascript and jQuery.

Use this code instead

 $(document).bind('mousemove', function(e){
   $('.box').css({
     top: e.pageY - $(".box").height()/2, // just minus by half the height
     left:  e.pageX - $(".box").width()/2 // just minus by half the width
   });
 });
