interact('.resize-drag')
  .draggable({
    onmove: function (event) {
      var target = event.target
      var x = (parseFloat(target.getAttribute('data-x')) || 0) + event.dx
      var y = (parseFloat(target.getAttribute('data-y')) || 0) + event.dy

      target.style.transform = 'translate(' + x + 'px, ' + y + 'px)'

      target.setAttribute('data-x', x)
      target.setAttribute('data-y', y)
    }
  })
  .resizable({

    edges: { left: true, right: true, bottom: true, top: true }
