修复 Bootstrap 导航栏链接向下展开的问题

Question

当我调整浏览器大小时，显示 "FIX" 的导航栏链接会下降到一列中。有谁知道我怎样才能防止这种情况发生并使链接保持在同一行上？

<!-- navbar -->
<nav class="navbar navbar-default">
  <div class="container-fluid">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="#">
        <div class="logo"><img style="width: 21px" src="logo" /></div>
      </a>
    </div> <!-- end of navbar header -->


    <!-- these links dont stay on the same line -->
    <ul class="nav navbar-nav pull-left">
      <li><a id="<%= @users ? 'active-page' : ''%>" href="/">FIX</a></li>
      <li><a id="<%= @users ? 'active-page' : ''%>" href="/">FIX</a></li>
      <li><a id="<%= @about ? 'active-page' : ''%>" href="/">FIX</a></li>
    </ul>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">

      <ul class="nav navbar-nav navbar-right">
        <li><a href="/">Sign up</a></li>
        <li><a href="/">Sign in</a></li>
      </ul>

      <form class="navbar-form navbar-right hidden-xs hidden-sm" role="search">
        <div class="form-group">
          <div class="search">
            <span class="fa fa-search"></span>
            <input type="text" class="form-control" placeholder="Search">
          </div>
        </div>
      </form>

    </div><!-- /.navbar-collapse -->
  </div><!-- /.container-fluid -->
</nav>

Answer 1

不要在导航栏左拉中使用。在自定义 bootstrap 中，导航栏默认样式在左侧。如果你想使用两侧，只需将 navbar-right 添加到导航的右侧。

Answer 2

您需要将这些链接放在navbar-header内，然后您可以使用诸如navbar-btn之类的助手来定位。也不要使用 pull-*，使用 navbar-left 或 navbar-right。参见 Docs。

查看工作示例代码段。
