Twitter Bootstrap 3 中的多个固定顶部导航栏标题

Question

• 引导程序 3.02

我想有 2 个固定到顶部导航栏，类似于 Joomla！ 3 实现了他们的浏览屏幕。

然后，一旦您滚动导航栏 #2 与顶部的对接：

我看过：

• Bootstrap 3 multiple navbars
• https://groups.google.com/forum/#!topic/twitter-bootstrap-stackoverflow/aAGJKArh-8E

但尝试多个 sn-ps 我无法让它工作。任何人都可以帮助在 jsFiddle 中进行工作演示吗？

Answer 1

Try this :
<div class="navbar navbar-fixed-top">
  <nav class="navbar navbar-default>
      navbar1
  </nav>

  <nav class="navbar navbar-default">
      navbar2
  </nav>
</div>

此代码适用于您。但是当 boostrap4 发布时，我认为最好使用该代码。

Answer 3

code below 是使用两个navbars 和affix 的基本开始。

HTML

<nav class="navbar navbar-default navbar-fixed-top" role="navigation">
  <div class="container">
    <div class="navbar-header">
      <a class="navbar-brand" href="#">Brand</a>
    </div>
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
      <ul class="nav navbar-nav">
        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a>
          <ul class="dropdown-menu">
            <li><a href="#">Action</a></li>
            <li><a href="#">Another action</a></li>
            <li><a href="#">Something else here</a></li>
            <li class="divider"></li>
            <li><a href="#">Separated link</a></li>
            <li class="divider"></li>
            <li><a href="#">One more separated link</a></li>
          </ul>
        </li>
        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a>
          <ul class="dropdown-menu">
            <li><a href="#">Action</a></li>
            <li><a href="#">Another action</a></li>
            <li><a href="#">Something else here</a></li>
            <li class="divider"></li>
            <li><a href="#">Separated link</a></li>
            <li class="divider"></li>
            <li><a href="#">One more separated link</a></li>
          </ul>
        </li>
      </ul>
    </div>
  </div><!-- /.container-fluid -->
</nav>
<div class="divide-nav">
  <div class="container">
    <p class="divide-text">Some Text Here</p>
  </div>
</div>
<nav class="navbar navbar-default navbar-lower" role="navigation">
  <div class="container">
    <div class="collapse navbar-collapse collapse-buttons">
      <form class="navbar-form navbar-left" role="search">
        <button class="btn btn-success">Button</button>
        <button class="btn btn-default">Button</button>
        <button class="btn btn-default">Button</button>
        <button class="btn btn-default">Button</button>
      </form>
    </div>
  </div>
</nav>
<div class="container">
  <div class="row">
    <div class="filler"></div>
  </div>
</div>

CSS

body{
  margin-top: 50px;
}

.divide-nav{
  height: 50px;
  background-color: #428bca;
}

.divide-text{
    color:#fff;
    line-height: 20px;
    font-size:20px;
    padding: 15px 0;
}

.affix {
  top: 50px;
  width:100%;
}

.filler{
  min-height: 2000px;
}

.navbar-form {
   padding-left: 0;
}

.navbar-collapse{
   padding-left:0; 
}

JavaScript

$('.navbar-lower').affix({
  offset: {top: 50}
});
