<script>
function id(id){
    return document.getElementById(id)
}
console.log(id('droppable').offsetWidth,id('droppable').offsetTop)
id('draggable').style.left =id('droppable').offsetWidth+'px'
id('draggable').style.top = id('droppable').offsetTop+'px'

var bound = id('droppable').getBoundingClientRect();

var x= bound.left,y= bound.top 

id('draggable').style.left =x+'px'
id('draggable').style.top = y+'px'
