   theme: 'snow'

quill.on('text-change', function(delta, oldDelta, source) {
   if (source == 'user') {
      var editor_content = document.querySelectorAll('#editor img');
      for (var i = 0; i < editor_content.length; i++) {
         var image = editor_content[i];
         var alignment = image.getAttribute('data-align');
