导航栏不会随着屏幕尺寸大于 md-breakpoint Bootstrap 进行缩放
Navbar doesn't scale with screensize bigger than md-breakpoint Bootstrap
在我当前的项目中，我有一个带有汉堡菜单的导航栏。它正确缩放到 md-breakpoint，但在此断点之后所有元素都向左移动并且切换工作很奇怪。
中等：
view on medium
在笔记本电脑 L - 1440px 上：
view on larger than medium
这是我现在 header header 的代码，但我似乎无法弄清楚是什么让我的导航栏表现得如此奇怪，因为我没有指定 md 和>MD.
<header>
<div class="container ">
<nav class="navbar bg-light navbar-light fixed-top ">
<button class="navbar-toggler align-items-center" type="button" data-toggle="collapse" data-target="#navDropdownMenu" aria-controls="navbarDropdownToggle" aria-expanded="false" aria-label="Toggle navigation">

</button>
<a class="navbar-brand mx-auto" href="index.html">FORRESTR</a>
<button class="shoppingCart navbar-toggler" type="button">

<div class="container">

有人知道问题出在哪里吗？

除了将 class .fixed-top 移动到您的容器之外，如果您想要全宽 header，则必须使用 .container-fluid。另外，您必须移除包裹 narvbar-collapse 的容器。否则我也会对断点做出反应。

@Periplo 这是将固定顶部 class 从导航栏替换到父容器后的样子。
After added fixed-top to container instead of navbar
不完全是我想要的，因为我想要一个全角导航栏 :)。这是我的 html 代码：
