我如何根据导航栏的高度向下推最左边的列a position-fixed，其中有fixed-top？
下面是我的HTML：
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet"
integrity="sha384-giJF6kkoqNQ00vy+HMDP7azOuL0xtbfIcaT9wjKHr8RbDVddVHyTfAAsrekwKmP1" crossorigin="anonymous">
<style>
html,
body {
height: 100%!important;
}
.navbar-brand img {
filter: invert(65%) sepia(91%) saturate(7314%) hue-rotate(210deg) brightness(101%) contrast(98%);
}
</style>
<style>
.scrollable {
overflow: hidden;
height: 100%!important; /* Otherwise we have to use h-100 on the .scrollable section?!? */
}
.scrollable:hover {
overflow: auto;
}
::-webkit-scrollbar {
width: 3px;
height: 3px;
background-color: #F5F5F5;
}
::-webkit-scrollbar-track {
background-color: #FEFEFE;
}
::-webkit-scrollbar-thumb {
background-color: #6c757d;
}
</style>
<title>BS5 Layout</title>
</head>
<body class="bg-light">
<header class="navbar navbar-light bg-light fixed-top p-0 border-bottom">
<div class="col-12 col-md-3 col-lg-2">

</div>
<nav class="col-12 col-md-9 col-lg-10 border-start" aria-label="breadcrumb">

<li class="breadcrumb-item"><a href="#">Home</a></li>
<li class="breadcrumb-item"><a href="#">Contacts</a></li>
<li class="breadcrumb-item active" aria-current="page">List</li>
</ol>
</nav>
</header>
<div class="container-fluid h-100">
<div class="row h-100">
<section class="h-100 col-md-3 col-lg-2 position-fixed p-0 scrollable">
This won't scroll all the way to bottom?!?

...
Last item
</section>
<section class="h-100 col-md-5 col-lg-7 offset-md-3 offset-lg-2 p-0 border-start">
Repeat this content and navbar disappears after X number of scrolls<br>
...
Last line<br>
</section>
<section class="h-100 col-md-4 col-lg-3 p-0 border-start">
SIDE
</section>
</div>

**正文填充是必需的，因为你的导航是固定的！**来自另一个引用旧版本文档的答案：
固定的导航条将覆盖您的其他内容，除非您在
<body>的顶部添加填充。尝试您自己的值或使用我们下面的片段。提示：默认情况下，导航条为50 px高。字符串
在bootstrap stuff！Working demo和code之后包含这一行！
