twitter-bootstrap - 导航栏中的中心标题 - 引导程序

Question

我有一个响应式导航栏，并希望将标题居中。除了标题“标题”之外，其他任何功能或定位都不需要更改。

<link href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.css" rel="stylesheet" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.js"></script>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.css" rel="stylesheet" />
<script src="https://code.jquery.com/jquery-3.4.1.slim.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.js"></script>
<nav class="navbar navbar-expand-sm bg-dark navbar-dark justify-content-end">
  <a class="navbar-brand d-none d-sm-block" href="#">Brand</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent">
    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="navbar-brand mx-auto d-block text-center order-0 order-md-0 w-25">Title</div>
  <div class="navbar-collapse collapse dual-nav w-50 order-2 order-md-0" id='navbarSupportedContent'>
    <ul class="navbar-nav ml-auto">
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="//codeply.com">Codeply</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li>
    </ul>
  </div>
  <button class="btn btn-success ml-auto mr-2 d-block d-sm-none">Always Show</button>
</nav>

请就此给我建议。

谢谢。

Bootstrap 4 导航栏现在使用 flexbox，因此标题可以使用 mx-auto 居中。检查这个答案，更多引导导航栏
