我有一些简单的列保留在视口中。无论你做什么，它都会停留在视口上(缩小，它们都停留在屏幕上而不滚动(。目前，我的导航栏附在中间一列，但如果我把它放在外面，页面就会变成可滚动的。我将提供的代码是完全工作的，除了我希望导航栏在外面，例如：
这个
--------------------
col1 | navbar | col3
| col2 |
--------------------
进入这个
--------------------
navbar
col1 | col2 | col3
--------------------
所以所有这些都需要在一个视口上(不需要像下面的示例代码那样滚动(。我想列保持在一行中，但导航栏在它之外，仍然可以一起使用vh-100。
