我正在使用内置 Bootstrap 版本 2.3.2 构建一个 joomla 模板。问题是我在平板电脑上有很长的导航栏，它分成两行我想让它在 1200 像素处折叠。我正在使用以下代码进行导航。

<?php
defined('_JEXEC') or die;

// Add JavaScript Frameworks
JHtml::_('bootstrap.framework');

// Load optional rtl Bootstrap css and Bootstrap bugfixes
JHtmlBootstrap::loadCss($includeMaincss = true);

?>
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<jdoc:include type="head" />
  <!--[if lt IE 9]>
    <script src="<?php echo $this->baseurl ?>/media/jui/js/html5.js"></script>
  <![endif]-->
<link href="templates/test/css/template.css" rel="stylesheet" type="text/css">
</head>
<body>
<div class="container">
<div class="row-fluid">
        <div id="logo" class="span12"><a href="home.html"><img src="templates/test/images/logo.png" alt="Home - Freeterm Limited, London"></a></div>
</div>
</div>
<div class="container">
<div class="row-fluid">
  <nav class="span12 navbar">
     <div class="navbar-inner">
            <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>
     <div class="nav-collapse collapse"><jdoc:include type="modules" name="nav" style="none" /></div>
     </div>
  </nav>
</div></div>

CSS 如下:

.navbar {
    margin: 0px;
}

.navbar-inner {

  padding-left: 0px;
  padding-right: 0px;

  background-image: -webkit-linear-gradient(top, #363f45, #363f45);
  background-image: -o-linear-gradient(top, #363f45, #363f45);

最佳答案

just add this in your css file

@media (max-width: 1000px) {
  .navbar-header {
      float: none !important;
  }
  .navbar-default {
    background-color: #222 !important;
    border-color: transparent;
    padding:0px !important;
}
.nav > li {
    display: block !important;
    position: relative;
}
.navbar-left, .navbar-right {
    float: none !important;
}
.navbar-nav > li.navbar-right {
    float: none !important;
}
.navbar{
	
	min-height:50px;
	position:relative;
}
  .navbar-left,.navbar-right {
      float: none !important;
  }
  .navbar-toggle {
      display: block !important;
  }
  .navbar-collapse {
      border-top: 1px solid transparent;
      box-shadow: inset 0 1px 0 rgba(255,255,255,0.1);
  }
  .navbar-fixed-top {
      top: 0;
      border-width: 0 0 1px;
  }
  .navbar-collapse.collapse {
      display: none !important;
  }
  .navbar-nav {
      float: none!important;
      margin-top: 7.5px;
  }
  .navbar-nav>li {
      float: none !important;
  }
  .navbar-nav>li>a {
      padding-top: 10px;
      padding-bottom: 10px;
  }
  .collapse.in{
      display:block !important;
  }
}
