我是第一次在 .NET MVC(非核心)入门应用程序中使用 Bootstrap 4。 Nuget 中的 Bootstrap 版本已更新至 4.1。
我需要在顶部有一个水平导航栏，在左侧有一个垂直导航栏(边栏)。
我一直在研究的例子: https://getbootstrap.com/docs/4.1/examples/dashboard/
我遇到的问题是侧边栏只能向下延伸到主页内容，我无法让它向下延伸到页面的 100%。我尝试在导航栏和侧边栏相关的 div 上手动设置高度，但没有效果。
_Layout.cshtml :
<body>
<nav class="navbar navbar-dark fixed-top bg-dark flex-md-nowrap p-0 shadow">
<a class="navbar-brand col-sm-3 col-md-2 mr-0" href="#">Company name</a>
<ul class="navbar-nav px-3">
<li class="nav-item text-nowrap">
<a class="nav-link" href="#">Sign out</a>
</li>
</ul>
</nav>
<div class="container-fluid">
<div class="row">
<nav class="col-md-2 d-none d-md-block bg-light sidebar">
<div class="sidebar-sticky">
<ul class="nav flex-column">
<li class="nav-item">
<a class="nav-link active" href="#">

最佳答案
这有点棘手... Bootstrap 使用额外的 CSS 来完成这个布局。它不适用于 Bootstrap。他们添加了一个类“.sidebar”:
.sidebar {
position: fixed;
top: 0;
bottom: 0;
left: 0;
z-index: 100;
padding: 48px 0 0;
box-shadow: inset -1px 0 0 rgba(0, 0, 0, .1);
}
这是一个代码笔示例: https://codepen.io/anon/pen/oRjmBN
我还添加了一个 'overflow-y: auto' 以防侧边栏中的内容变长。
希望对您有所帮助!
