引导4中心导航条

Question

使用新的Bootstrap 4 v4.0.0-beta.2，我就找不到一种方法将内容集中在我的肚脐栏中。我什么都试过了！有什么想法吗？下面的代码。

前面的答案是关于引导4的ALPHA版本，我已经试过了它们！他们的解决方案不起作用。

​

<nav class="navbar navbar-expand-md navbar-light fixed-top">
    <a class="navbar-brand" href="/">
        <img src="/img/frontpage/logotest.png">logo
    </a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarsExampleDefault">
        <ul class="navbar-nav">
            <li class="nav-item"><a class="nav-link" href="/">Home</a></li>
        </ul>
    </div>
</nav>

Answer 1

试试这段代码。它适用于引导4，我刚刚将d-flex justify-content-center添加到导航条崩溃中。

​

<nav class="navbar navbar-expand-md navbar-light fixed-top">
    <a class="navbar-brand" href="/">
        <img src="/img/frontpage/logotest.png">logo
    </a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse d-flex justify-content-center" id="navbarsExampleDefault">
        <ul class="navbar-nav ">
            <li class="nav-item "><a class="nav-link" href="/">Home</a></li>
        </ul>
    </div>
</nav>
