Question

我想将我的内容放入导航栏中的3个不同的“列”中。我要的只是左边的徽标（选中）中心的一些导航项（选中）和右边的最后一个元素（获取应用），这是个问题。

这是我的代码：

<nav class="navbar navbar-expand-lg navbar-light bg-light">
    <a class="navbar-brand" href="#"><img src="img/Logo.png"></a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNavDropdown">
        <ul class="navbar-nav mx-auto">
        <li class="nav-item dropdown">
            <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
            Home
            </a>
            <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
            <a class="dropdown-item" href="#">Action</a>
            <a class="dropdown-item" href="#">Another action</a>
            <a class="dropdown-item" href="#">Something else here</a>
            </div>
        </li>
        <li class="nav-item active">
            <a class="nav-link" href="#">Features</a>
        </li>
        <li class="nav-item">
            <a class="nav-link" href="#">Pricing</a>
        </li>
        </ul>
        <ul class="navbar-nav mr-auto">
        <li class="nav-item">
            <a class="nav-link" href="#">Get The App</a>
        </li>
        </ul>
    </div>
</nav>

和CSS：

.navbar-nav.mr-auto ul li a.nav-link {
justify-content: right;
display: flex;
flex-wrap: wrap; }

这是我的结果：

我将不胜感激，谢谢;）

Answer 1

从上一个mr-auto中删除.navbar-nav类。
该类将margin-right: auto !important应用于您的元素，这使其向右边缘推送，就像mx-auto对auto的两面（左右）都应用相同的x一样。

看到它正常工作：

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet"/>
<nav class="navbar navbar-expand-lg navbar-light bg-light">
    <a class="navbar-brand" href="#"><img src="img/Logo.png"></a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNavDropdown">
        <ul class="navbar-nav mx-auto">
        <li class="nav-item dropdown">
            <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
            Home
            </a>
            <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
            <a class="dropdown-item" href="#">Action</a>
            <a class="dropdown-item" href="#">Another action</a>
            <a class="dropdown-item" href="#">Something else here</a>
            </div>
        </li>
        <li class="nav-item active">
            <a class="nav-link" href="#">Features</a>
        </li>
        <li class="nav-item">
            <a class="nav-link" href="#">Pricing</a>
        </li>
        </ul>
        <ul class="navbar-nav">
        <li class="nav-item">
            <a class="nav-link" href="#">Get The App</a>
        </li>
        </ul>
    </div>
</nav>

Answer 2

您必须摆脱类margin-right: auto !important的{{1}}。

如果不需要，只需删除类.mr-auto。
