html - Bootstrap 导航栏更改按钮和菜单位置

Question

我正在使用 Bootstrap 导航栏创建网站标题，如下所示:

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet"/>
<nav class="navbar navbar-expand-sm navbar-dark bg-dark">
  <a class="navbar-brand all-upper mb-1 h1 ml-1" href="#">Brand</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarToggle" aria-controls="navbarToggle" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>

  <div class="navbar-expand">
    <button class="btn btn-primary mr-3" onclick="goToTrip()">Button</button>
  </div>

  <div class="collapse navbar-collapse">
    <ul class="navbar-nav ml-auto">
      <li class="nav-item">
        <a class="nav-link all-upper" href="index.html">Home</a>
      </li>
      <li class="nav-item">
        <a class="nav-link all-upper" href="#">Settings</a>
      </li>
      <li class="nav-item">
        <a class="nav-link all-upper" href="#">Log Out</a>
      </li>
    </ul>
  </div>
</nav>

所以我在导航栏右侧有一些链接，在左侧有一个按钮。

但是当屏幕变小时，按钮和折叠菜单会像这样改变它们的位置:

没有按钮一切正常:

那么如何将元素安放好呢？

Answer 1

@media screen and (max-width: 540px) {
   .navbar-brand{
       flex-grow: 2;
   }
}

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet"/>
    <nav class="navbar navbar-expand-sm navbar-dark bg-dark">
      <a class="navbar-brand all-upper mb-1 h1 ml-1" href="#">Brand</a>


      <div class="navbar-expand">
        <button class="btn btn-primary mr-3" onclick="goToTrip()">Button</button>
      </div>  
      <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarToggle" aria-controls="navbarToggle" aria-expanded="false" aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </button>

      <div class="collapse navbar-collapse">
        <ul class="navbar-nav ml-auto">
          <li class="nav-item">
            <a class="nav-link all-upper" href="index.html">Home</a>
          </li>
          <li class="nav-item">
            <a class="nav-link all-upper" href="#">Settings</a>
          </li>
          <li class="nav-item">
            <a class="nav-link all-upper" href="#">Log Out</a>
          </li>
        </ul>
      </div>
    </nav>

你能试试这个吗？你只是把你的 navbar-toggler 放在了错误的地方..

再试一次？这就是你想要的？
