同学你好,不是兼容性的问题,是因为设置了显示隐藏,具体可以到另一个问题中进行查看。

同学你好,关于你的问题,解答如下:

由于layout.css文件使用的是课程中的,所以在样式上有点区别;

1、如下,是指左侧的这个子菜单显示吗?这里测试是有显示的,不过有部分被遮盖了,建议:可以设置下层级。

2、点击返回顶部这里测试是有效的,是使用的谷歌浏览器进行测试,同学可以在测试下。

若还是无法解决,可以将完整的代码粘贴过来,便于准确的定位与解决问题。

祝学习愉快!

    老师,全部代码和截图,我已经重新提问了,在我最新提问里。情况是:谷歌浏览器,按f12开发者模式在下面,会出现箭头。正常情况下没有出现。考虑是代码的兼容性问题。
