Question

这个Bootstrap中可折叠打开/关闭面板的代码正常打开但是当打开它时它的问题只有在我打开另一个时才会关闭，我在在线编辑器中测试它的工作但不能在我的web应用程序中工作我不知道为什么。

.panel-heading [data-toggle="collapse"]:after {
  font-family: 'Glyphicons Halflings';
  content: "\e072";
  float: right;
  color: #183F66;
  font-size: 18px;
  line-height: 22px;
  -webkit-transform: rotate(-90deg);
  -moz-transform: rotate(-90deg);
  -ms-transform: rotate(-90deg);
  -o-transform: rotate(-90deg);
  transform: rotate(-90deg);
}
