  <div drag style="height:100px;width:100px;background-color:green;margin:10px;"></div>
  <div drag style="height:100px;width:100px;background-color:green;margin:10px;"></div>
</div>
<script type="text/javascript" src="./dist/dragable.js"></script>

  var containerDrag = dragable(document.querySelectorAll(".container"))
</script>
