Question

好吧，我想使用Bootstrap 4 Navbar来实现这个目标：https://i.imgur.com/BDM7JvD.jpg。

如何使用flexbox或mr-auto etc实用程序集中视口中间的nav-links /项目。我试图避免基于CSS的定位方法，因为它可能会在不同的设备上查看。但是，确定CSS方法是否有望处于同一集中位置，那么为什么不呢！

注意：某些人可能会说使用justify实用程序，舞会是你不能将它们用作navbar-brand而navbar-nav不能包含在div中。如果我这样做，布局就会混乱。

nav class =＆＃34; navbar navbar-toggleable-md navbar-light bg-custom card-shadow-bottom＆＃34;＆gt;

        <div class="container">

            <button class="navbar-toggler navbar-toggler-right" 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>

            <a class="navbar-brand" href="#"><img src="img/nav-logo.png" alt="logo" class="nav-logo"></a>

            <div class="collapse navbar-collapse" id="navbarSupportedContent">
                <ul class="navbar-nav ml-auto mr-auto">
                    <li class="nav-item">
                        <a class="nav-link" href="#">Home</a>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link" href="#">Link</a>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link" href="#">Disabled</a>
                    </li>
                </ul>
            </div>

        </div>

    </nav>

使用flexbox实用程序以您希望的方式对齐组件。此处justify-content-center用于居中navbar-nav。

<nav class="navbar navbar-fixed-top navbar-toggleable-sm navbar-inverse bg-primary justify-content-between">
    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#collapsingNavbar">
        <span class="navbar-toggler-icon"></span>
    </button>
    <a href="/" class="navbar-brand">Brand</a>
    <div class="navbar-collapse collapse justify-content-center" id="collapsingNavbar">
        <ul class="navbar-nav">
            <li class="nav-item active">
                <a class="nav-link" href="#">Link <span class="sr-only">Home</span></a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Link</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#" data-toggle="collapse">Link</a>
            </li>
        </ul>

    </div>
    <ul class="nav navbar-nav flex-row">
        <li class="nav-item"><a class="nav-link pr-3" href=""><i class="fa fa-facebook"></i></a></li>
        <li class="nav-item"><a class="nav-link" href=""><i class="fa fa-twitter"></i></a></li>
    </ul>
</nav>
