导航栏是一个很好的功能,是 Bootstrap 网站的一个突出特点。导航栏在您的应用或网站中作为导航页头的响应式基础组件。导航栏在移动设备的视图中是折叠的,随着可用视口宽度的增加,导航栏也会水平展开。在 Bootstrap 导航栏的核心中,导航栏包括了站点名称和基本的导航定义样式。本文主要介绍了详解bootstrap导航栏.nav与.navbar区别,小编觉得挺不错的,现在分享给大家,也给大家做个参考希望能帮助到大家。

一、简单的ul,li组成的导航:

<ul class="nav nav-pills justify-content-center bg-dark nav-dark">
    <li class="nav-item">
      <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="nav-link">1</a>
    </li>
    <li class="nav-item">
      <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="nav-link">2</a>
    </li>
    <li class="nav-item">
      <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="nav-link">3</a>
    </li>
  </ul>

 

//解析:.nav .nav-item .nav-link表示ul li是导航——.nav-pills表示胶囊状导航——.bg-dark/.nav-dark表示黑底白字——.justify-content-center表示导航栏在浏览器上居中显示

在浏览器上显示为:

 

缩小浏览器窗口显示为:
