我有两个 div 内容，但事实证明，当我滚动时，一个 div 覆盖在另一个 div 之上，我该如何阻止这种情况发生在我身上？

这是你加载页面时的结果，显然加载正常

当我向下滚动时，它会关闭导航菜单

Answer 1

编辑（根据 Ghunter 的评论）：

将标题元素的 z-index 更改为大于 0 的任何值即可。

旧答案：

这是一个堆叠问题。你有 .navbar 作为 z-index: 0; .contendor div 是相对的，没有定义 z-index。所以逻辑是堆叠在 .navbar 的顶部将 .navbar 设置为 z-index: 99;以确保其始终处于领先地位。*
