  <div :class="{fullscreen:fullscreen}" class="tinymce-container" :style="{width:containerWidth}">
    <textarea :id="tinymceId" class="tinymce-textarea" />
    <div class="editor-custom-btn-container">
      <editorImage color="#1890ff" class="editor-upload-btn" @successCBK="imageSuccessCBK" />
    </div>
  </div>
