侧边栏粘在页面顶部而不是屏幕顶部

问题描述 投票：0回答：1

我是 Web 开发新手，目前正在开发一个基于 django 和 bootstrap 5.3.3 的投资组合网站，我的侧边栏粘在页面顶部而不是用户屏幕顶部有问题（我需要无论用户位于页面上的哪个位置，它都对用户可见）。我尝试过使用引导类

sticky-top
，但它似乎没有对其行为做出任何改变。 这是我的代码：

我发现这个问题过去已经被问过，但解决方案对我以及提出问题的人都不起作用： 如何在 Bootstrap 5.2 中设置侧边栏“粘性” ChatGPT 也没有帮助。 其他网站的答案令人困惑。

我已从 

sticky-top
中删除了 
container-fluid
。我还从 
flex-nowrap
中删除了 
row
。我在 
sidebar
中添加了以下内容，使其在任何屏幕尺寸下都为 
fixed
和 
scrollable
： 
position-fixed
top-0
bottom-0
start-0
overflow-auto
。

我在主体容器中添加了

ms-auto
。我还更新了不同屏幕尺寸下的 
col
宽度，但您当前的 
code
不适合移动视图。因此，请也调整您的侧边栏以适应移动视图。

我已经解决了您当前的问题。请查看以下
