根据bootstrap文档,添加aria-hidden="true"告诉辅助技术跳过模态的DOM元素,这解释aria-hidden=true了主要的存在modal div.

添加aria-hidden=true模态关闭按钮的目的是什么modal-header div？

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      **<*div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;       </button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>***
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
</div><!-- /.modal -->
