我在网上找不到类似的东西，所以我问你们！问题是我的图标与折叠的导航栏重叠

我的代码：

从您的代码示例来看，罪魁祸首似乎是

#sicons

的值为

位置：绝对。绝对定位的项目将始终位于相对位置的项目之上。尝试为您的导航栏和
#sicons
容器分配
z-index
值，使
#sicons
的值低于您的导航栏

有关
z-index
如何工作、它如何与定位元素交互以及堆叠顺序的更多信息，请查看此堆栈溢出问题的答案：
Banzay omg非常感谢。您是如何做到的？非常感谢。：）嗯，我把它设为相对的，但它仍然重叠，还有一个问题我应该用位置吗：绝对？因为有时它不能很好地与引导一起工作。@reimiux您的导航栏有一个
z-index
值吗？使用绝对定位没有错。不过，如果您了解z-index的工作原理，就更容易使用它。我用一篇文章更新了我的答案以供参考。是的，他们都有我的#sicons和我的导航栏的z-index:999。图标仍然重叠。多亏了你，我学会了如何使用X和s的相对位置！我一直在寻找，我甚至想在stackoverflow写一篇文章。但是我自己发现了：）非常感谢
