Bootstrap 4导航栏布局使用CDN进行工作，使用下载的代码中断 [英] Bootstrap 4 navbar layout works using CDN, breaks using downloaded code

问题描述

使用下载的Bootstrap 4 Alpha代码折叠并折叠了导航栏，但使用Bootstrap 4 Alpha CDN看起来没有问题.对于该项目，必须使用下载的代码.

Navbars load collapsed and improperly formatted using downloaded Bootstrap 4 Alpha code, but appear fine using the Bootstrap 4 Alpha CDN. Using the downloaded code is necessary for this project.

使用下载的Bootstrap 4 Alpha代码显示的导航栏外观: 查看图像

Navbar appearance using downloaded Bootstrap 4 Alpha code: View image

使用Bootstrap 4 Alpha CDN的导航栏外观(我想要的外观):查看图像

Navbar appearance using Bootstrap 4 Alpha CDN (the look I want): View image

这是我的HTML，不会改变:

This is my HTML, it doesn't change:

<nav class="navbar navbar-expand-lg navbar-light">
    <div class="container">
        <a class="navbar-brand" href="#">Brand</a>
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </button>
        <div class="collapse navbar-collapse" id="navbarSupportedContent">
            <ul class="navbar-nav ml-auto">
                <li class="nav-item active">
                    <a class="nav-link" href="#">About Us <span class="sr-only">(current)</span></a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Meet the Team</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Log In</a>
                </li>
            </ul>
        </div>
    </div>
</nav>

不知道这是什么问题或如何解决.有人熟悉这个问题吗?谢谢

No idea what's wrong or how to fix this. Anyone familiar with this issue? Thanks

推荐答案

来自将Beta 4的Bootstrap引导至Beta ，navbar-toggleable-*更改为navbar-expand-*，因此，如果将navbar-expand-*与alpha结合使用，将无法正常工作.

From Bootstrap 4 alpha 6 to beta, navbar-toggleable-* changed to navbar-expand-*, so if you're using navbar-expand-* with alpha it wouldn't work.

如果您希望它在 alpha 6 中运行，它将是:

If you want it to work in alpha 6, it would be:

<nav class="navbar navbar-toggleable-md navbar-light">..</nav>

如果您希望它在 beta 中运行，则应该是:

If you want it to work in beta, it would be:

<nav class="navbar navbar-expand-lg navbar-light">..</nav>
