Twitter Bootstrap品牌仅在折叠模式下显示

Question

我正在使用twitter bootstrap响应导航栏,我试图弄清楚如何只在导航栏处于折叠模式时才显示该品牌.

我想可能需要一些额外的js,但我不确定那是什么或放在哪里.

这是我得到的:

<div class="navbar">
  <div class="navbar-inner">
    <div class="container">

  <!-- .btn-navbar is used as the toggle for collapsed navbar content -->
  <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
  </a>

  <!-- Be sure to leave the brand out there if you want it shown -->
  <a class="brand" href="#">Navigation</a>

  <!-- Everything you want hidden at 940px or less, place within here -->
  <div class="nav-collapse collapse">
    <!-- .nav, .navbar-search, .navbar-form, etc -->

        <ul class="nav nav-pills">
          <li><a href="#">Nav 1</a></li>
          <li><a href="#">Nav 2</a></li>
          <li class="dropdown">
            <a class="dropdown-toggle"
               data-toggle="dropdown"
               href="#">
                Programs
                <b class="caret"></b>
              </a>
            <ul class="dropdown-menu">
              <!-- links -->
              <li><a href="#">Program 1</a></li>
              <li><a href="#">Program 2</a></li>
              <li><a href="#">Program 3</a></li>
              <li class="divider"></li>
              <li><a href="#">Program A</a></li>
              <li><a href="#">Program B</a></li>
              <li><a href="#">Program C</a></li>
          </ul> <!-- closes dropdown menu -->
          </li> <!-- closes dropdown class -->
        </ul>   <!-- closes nav-pills -->   
  </div> <!-- closes collapse -->
</div> <!-- closes container -->
</div> <!-- closes navbar-inner -->
</div> <!-- closes overall navbar -->

现在,品牌一直在显示,但我希望它只在折叠模式下显示,以便观众知道这是导航栏.他们不需要在更大的屏幕模式下看到它.

任何资源都可能有所帮

谢谢你的时间.

Answer 1

解决此问题的简单方法是使用Bootstrap提供的响应实用程序类:

Bootstrap 4:

资源

Bootstrap 4 alpha:

Bootstrap 3:

例:

<a class="brand hidden-lg" href="#">Navigation</a>

Bootstrap 2:

例:

<a class="brand hidden-desktop" href="#">Navigation</a>

Answer 2

对于Bootstrap 3,请使用以下类Ref:http://getbootstrap.com/css/#responsive-utilities-classes

Answer 3

由于Bootstrap3.2 visible-xs,不推荐使用visible-sm等.参考:http://getbootstrap.com/css/#responsive-utilities-classes

所以在这种情况下你应该使用:

<a class="brand visible-xs-block" href="#">Navigation</a>

要么

<a class="brand visible-xs-inline" href="#">Navigation</a>

要么

<a class="brand visible-xs-inline-block" href="#">Navigation</a>

取决于display应该对此链接应用的属性类型.

Navigation只有在您的导航折叠时,才会显示您的品牌链接
