导航栏不随屏幕尺寸大于 md-breakpoint Bootstrap 缩放答案

【问题标题】：Navbar doesn't scale with screensize bigger than md-breakpoint Bootstrap导航栏不随屏幕尺寸大于 md-breakpoint Bootstrap 缩放
【发布时间】：2019-10-21 12:31:03
【问题描述】：

在我当前的项目中，我有一个带有汉堡菜单的导航栏。它可以正确缩放到 md 断点，但是在这个断点之后，所有元素都向左移动，并且切换工作很奇怪。

在介质上： view on medium 在笔记本电脑 L - 1440px 上： view on larger than medium 这是我现在的标题代码，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 之间的任何不同。

<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">
      <i class="fa fa-bars"></i>
    </button>

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

    <button class="shoppingCart navbar-toggler" type="button">
      <i class="fa fa-shopping-cart"></i>
    </button>

    <div class="container">
      <div class="collapse navbar-collapse" id="navDropdownMenu">
        <ul class="navbar-nav">
          <a class="nav-item nav-link active" href="index.html">Products</a>
          <a class="nav-item nav-link" href="ourstory.html">Our Story</a>
          <a class="nav-item nav-link" href="partners.html">Partners</a>
          <a class="nav-item nav-link" href="process.html">Process</a>
          <a class="nav-item nav-link" href="contact.html">Contact Us</a>
          <a class="nav-item nav-link" href="faq.html">FAQ</a>
        </ul>
      </div>
    </div>
  </nav>
</div>

有谁知道问题出在哪里？

更新

除了将.fixed-top 类移动到您的容器之外，如果您想要一个全宽标题，您必须使用.container-fluid。另外，您必须删除包装 narvbar-collapse 的容器。否则我也会对断点做出反应。

<header class="container-fluid fixed-top">
    <nav class="navbar  navbar-light">
        <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">
            <i class="fa fa-bars"></i>
        </button>

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

        <button class="shoppingCart navbar-toggler" type="button">
            <i class="fa fa-shopping-cart"></i>
        </button>

        <div class="collapse navbar-collapse" id="navDropdownMenu">
            <ul class="navbar-nav">
                <a class="nav-item nav-link active" href="index.html">Products</a>
                <a class="nav-item nav-link" href="ourstory.html">Our Story</a>
                <a class="nav-item nav-link" href="partners.html">Partners</a>
                <a class="nav-item nav-link" href="process.html">Process</a>
                <a class="nav-item nav-link" href="contact.html">Contact Us</a>
                <a class="nav-item nav-link" href="faq.html">FAQ</a>
            </ul>
        </div>
    </nav>
</header>

您从未说过您在原始帖子中需要全角标题，我刚刚更新了我的答案。请使用 cmets 评论某人的答案。
对不起，你是对的，我忘记了一个非常重要的细节（哎呀）。但是你很棒！该代码有效，看起来非常好！谢谢你
没关系，我很乐意提供帮助。

【解决方案2】：

@Periplo 这是将固定顶类从导航栏替换为父容器后的样子。

After added fixed-top to container instead of navbar 不是我要找的东西，因为我想要一个全宽的导航栏:)。这是我的html代码：
