对于Bootstrap 4 beta，元素对齐到右侧的示例导航栏是:

<div id="app" class="container">
  <nav class="navbar navbar-expand-md navbar-light bg-faded">
    <button class="navbar-toggler navbar-toggler-right" 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>
    <a class="navbar-brand" href="#">Navbar</a>
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Features</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Pricingg</a>
      </li>
    </ul>
    <ul class="navbar-nav">
      <li class="nav-item">
        <a class="nav-link" href="{{ url('/login') }}">Login</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="{{ url('/register') }}">Register</a>
      </li>
    </ul>
  </nav>
</div>

在我的情况下，我只想要一组导航按钮/选项，并发现这将工作:

<div class="collapse navbar-collapse justify-content-end" id="navbarCollapse">
  <ul class="navbar-nav">
    <li class="nav-item">
      <a class="nav-link" href="#">Sign Out</a>
    </li>
  </ul>
</div>

因此，您将在div中添加justify-content-end，并在列表中省略mr-auto。

下面是一个工作示例。

对于Bootstrap 4 beta，元素对齐到右侧的示例导航栏是:

<div id="app" class="container">
  <nav class="navbar navbar-expand-md navbar-light bg-faded">
    <button class="navbar-toggler navbar-toggler-right" 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>
    <a class="navbar-brand" href="#">Navbar</a>
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Features</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Pricingg</a>
      </li>
    </ul>
    <ul class="navbar-nav">
      <li class="nav-item">
        <a class="nav-link" href="{{ url('/login') }}">Login</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="{{ url('/register') }}">Register</a>
      </li>
    </ul>
  </nav>
</div>

使用引导伸缩盒会有所帮助 我们来控制您的导航元素的位置和对齐。 对于上述问题，添加mr-auto是一个更好的解决方案。

<div id="app" class="container">
  <nav class="navbar navbar-toggleable-md navbar-light bg-faded">
    <button class="navbar-toggler navbar-toggler-right" 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>
    <a class="navbar-brand" href="#">Navbar</a>
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Features</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Pricingg</a>
      </li>
    </ul>
    <ul class="navbar-nav  " >
      <li  class="nav-item">
        <a class="nav-link" href="{{ url('/login') }}">Login</a>
      </li>
      <li  class="nav-item">
        <a class="nav-link" href="{{ url('/register') }}">Register</a>
      </li>
    </ul>
  </nav>
  @yield('content')
</div>

其他安置可能包括

fixed- top
    fixed bottom
    sticky-top

我是栈溢出的新手，也是前端开发的新手。这对我来说很管用。所以我不希望显示列表项。

.hidden { display:none; } #loginButton{ margin-right:2px; } <nav class="navbar navbar-toggleable-md navbar-light bg-faded fixed-top"> <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="#">NavBar</a> <div class="collapse navbar-collapse" id="navbarSupportedContent"> <ul class="navbar-nav mr-auto"> <li class="nav-item active hidden"> <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a> </li> <li class="nav-item hidden"> <a class="nav-link" href="#">Link</a> </li> <li class="nav-item hidden"> <a class="nav-link disabled" href="#">Disabled</a> </li> </ul> <form class="form-inline my-2 my-lg-0"> <button class="btn btn-outline-success my-2 my-sm-0" type="submit" id="loginButton"><a href="#">Log In</a></button> <button class="btn btn-outline-success my-2 my-sm-0" type="submit"><a href="#">Register</a></button> </form> </div> </nav>

令人惊讶的是，上面的答案并不适合我，所以下面是我的方法。要使登录和注册导航栏项向右对齐，您可以使用以下两种方法中的任何一种:

扯: 修改用于登录和注册为的无序列表标记 <ul class="navbar-nav - pull-right"> navbar-right: 修改用于登录和注册为的无序列表标记 <ul class="navbar-nav navbar-right">
