我看了看其他帖子，似乎找不到这个问题的答案。
我正在尝试使用 Bootstrap 制作网页。我想要一个固定在左侧的垂直 nabvar，占据 3 列，右侧的内容占据 9 列。我已经实现了 scrollspy 来在滚动时更新导航栏。
在我缩小屏幕之前，它工作得很好。我的理解是它应该将列放在彼此之上。如果我从列中删除词缀属性，它会正确更新，但导航栏未固定，因此 scrollspy 毫无意义。
这是我的代码:
ul.nav-pills {
padding-top: 20px;
top: 20px;
}
.item {
padding-top: 70px;
}
#content {
margin-bottom: 600px;
}<!DOCTYPE html>

最佳答案
尝试将“col-sm-9”更改为“col-md-9”或“col-lg-9”。哪个效果更好。或者使用“col-9”。
...
<div class="col-9">
<div id="about_me" class="container-fluid item">
<h1>About Me</h1>
<p>Try to scroll this section and look at the navigation bar while scrolling! Try to scroll this section and look at the navigation bar while scrolling!</p>
<p>Try to scroll this section and look at the navigation bar while scrolling! Try to scroll this section and look at the navigation bar while scrolling!</p>
