function get_position(id){
                  var rect = document.getElementById(id).getBoundingClientRect();
                  //hide the image for a moment and get the box id
                  document.getElementById(id).style.display = "none";
                  var elem = document.elementFromPoint(rect.left, rect.top);
                  document.getElementById(id).style.display = "";
                  //console.log(elem.id);
                  return elem ? elem.id : undefined
              }

              function moveImage(e) {
                var id = document.getElementById("image");
                
                
                  if(e.keyCode === 37){
                    id.style.left = parseInt(id.style.left) - 5 + 'px';
                  }
                  else if(e.keyCode === 38){
                    id.style.top = parseInt(id.style.top) - 5 + 'px';
                  }
                  else if(e.keyCode === 39){
                    id.style.left = parseInt(id.style.left) + 5 + 'px';
                  }
                  else if(e.keyCode === 40){
                    id.style.top = parseInt(id.style.top) + 5 + 'px';
                  }
                  
                  
                  
                  //find which box is overlapped.
                  let boxId = get_position("image");
                  if(boxId) console.log(boxId);
                  
              };

          window.onload = function(){
            window.addEventListener('keydown', moveImage);
            
          }
