css - 在右侧导航栏上移动一项

Question

我找不到使用 Bootstrap 样式将导航栏的最后一项(从左侧)移动到右侧的方法

有很多解决方案，如何将所有元素移动到右侧，但我只需要栏右侧的下拉菜单。

我该怎么做，只使用 Bootstrap CSS 类？

<div class="collapse navbar-collapse" id="navbarNavDropdown">
                <ul class="navbar-nav">
                    <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="#">About</a>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link" href="#">Contact</a>
                    </li>
                    <li class="nav-item dropdown navbar-right">
                        <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                        My account
                        </a>
                        <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
                            <a class="dropdown-item" href="#">Action</a>
                            <a class="dropdown-item" href="#">Another action</a>
                            <a class="dropdown-item" href="#">Something else here</a>
                        </div>
                    </li>
                </ul>
            </div>

Answer 1

你必须将 navs 分开，所有左边的 navs 都在一个里，右边的 navs 在另一个里，它有类 navbar-对了。

试试这个 HTML 结构:

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css" rel="stylesheet" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/js/bootstrap.min.js"></script>

<div class="navbar">
  <div class="collapse navbar-collapse" id="navbarNavDropdown">
    <ul class="nav navbar-nav">
      <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="#">About</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Contact</a>
      </li>
    </ul>
    <ul class="nav navbar-nav navbar-right">
      <li class="nav-item dropdown">
        <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
            My account
        </a>
        <ul class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
          <li><a class="dropdown-item" href="#">Action</a></li>
          <li><a class="dropdown-item" href="#">Another action</a></li>
          <li><a class="dropdown-item" href="#">Something else here</a></li>
        </ul>
      </li>
    </ul>
  </div>
</div>

For results, Run code snippet in Expanded view.
