• Bootstrap组件1


    导航条

    导航条是在您的应用或网站中作为导航页头的响应式基础组件。它们在移动设备上可以折叠(并且可开可关),且在视口(viewport)宽度增加时逐渐变为水平展开模式。

    两端对齐的导航条导航链接已经被弃用了。

    <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="#">Brand</a>
        </div>
    
        <!-- 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">
            <li class="active"><a href="#">Link <span class="sr-only">(current)</span></a></li>
            <li><a href="#">Link</a></li>
            <li class="dropdown">
              <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></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 role="separator" class="divider"></li>
                <li><a href="#">Separated link</a></li>
                <li role="separator" class="divider"></li>
                <li><a href="#">One more separated link</a></li>
              </ul>
            </li>
          </ul>
          <form class="navbar-form navbar-left">
            <div class="form-group">
              <input type="text" class="form-control" placeholder="Search">
            </div>
            <button type="submit" class="btn btn-default">Submit</button>
          </form>
          <ul class="nav navbar-nav navbar-right">
            <li><a href="#">Link</a></li>
            <li class="dropdown">
              <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></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 role="separator" class="divider"></li>
                <li><a href="#">Separated link</a></li>
              </ul>
            </li>
          </ul>
        </div><!-- /.navbar-collapse -->
      </div><!-- /.container-fluid -->
    </nav>

    通过添加 .navbar-inverse 类可以改变导航条的外观。

    <nav class="navbar navbar-inverse">
      ...
    </nav>

    分页

    为您的网站或应用提供带有展示页码的分页组件,或者可以使用简单的翻页组件

    默认分页

    受 Rdio 的启发,我们提供了这个简单的分页组件,用在应用或搜索结果中超级棒。组件中的每个部分都很大,优点是容易点击、易缩放、点击区域大。

    <nav aria-label="Page navigation">
      <ul class="pagination">
        <li>
          <a href="#" aria-label="Previous">
            <span aria-hidden="true">&laquo;</span>
          </a>
        </li>
        <li><a href="#">1</a></li>
        <li><a href="#">2</a></li>
        <li><a href="#">3</a></li>
        <li><a href="#">4</a></li>
        <li><a href="#">5</a></li>
        <li>
          <a href="#" aria-label="Next">
            <span aria-hidden="true">&raquo;</span>
          </a>
        </li>
      </ul>
    </nav>

    禁用和激活状态

    链接在不同情况下可以定制。你可以给不能点击的链接添加 .disabled 类、给当前页添加 .active 类。

    <nav aria-label="...">
      <ul class="pagination">
        <li class="disabled"><a href="#" aria-label="Previous"><span aria-hidden="true">&laquo;</span></a></li>
        <li class="active"><a href="#">1 <span class="sr-only">(current)</span></a></li>
        ...
      </ul>
    </nav>

    我们建议将 active 或 disabled 状态的链接(即 <a> 标签)替换为 <span> 标签,或者在向前/向后的箭头处省略<a> 标签,这样就可以让其保持需要的样式而不能被点击。

    <nav aria-label="...">
      <ul class="pagination">
        <li class="disabled">
          <span>
            <span aria-hidden="true">&laquo;</span>
          </span>
        </li>
        <li class="active">
          <span>1 <span class="sr-only">(current)</span></span>
        </li>
        ...
      </ul>
    </nav>

    巨幕

    这是一个轻量、灵活的组件,它能延伸至整个浏览器视口来展示网站上的关键内容。(快速搭建一个小页面)

    <div class="jumbotron">
      <h1>Hello, world!</h1>
      <p>...</p>
      <p><a class="btn btn-primary btn-lg" href="#" role="button">Learn more</a></p>
    </div>

    如果需要让巨幕组件的宽度与浏览器宽度一致并且没有圆角,请把此组件放在所有 .container 元素的外面,并在组件内部添加一个 .container 元素。

    <div class="jumbotron">
      <div class="container">
        ...
      </div>
    </div>

    页头

    页头组件能够为 h1 标签增加适当的空间,并且与页面的其他部分形成一定的分隔。它支持 h1 标签内内嵌 small 元素的默认效果,还支持大部分其他组件(需要增加一些额外的样式)。

    <div class="page-header">
      <h1>Example page header <small>Subtext for header</small></h1>
    </div>

    缩略图

    通过缩略图组件扩展 Bootstrap 的 栅格系统,可以很容易地以网格的方式展示图像、视频、文本等内容。

    默认样式的实例

    Boostrap 缩略图的默认设计仅需最少的标签就能展示带链接的图片。

    <div class="row">
      <div class="col-xs-6 col-md-3">
        <a href="#" class="thumbnail">
          <img src="..." alt="...">
        </a>
      </div>
      ...
    </div>

    自定义内容

    添加一点点额外的标签,就可以把任何类型的 HTML 内容,例如标题、段落或按钮,加入缩略图组件内。

    <div class="row">
      <div class="col-sm-6 col-md-4">
        <div class="thumbnail">
          <img src="..." alt="...">
          <div class="caption">
            <h3>Thumbnail label</h3>
            <p>...</p>
            <p><a href="#" class="btn btn-primary" role="button">Button</a> <a href="#" class="btn btn-default" role="button">Button</a></p>
          </div>
        </div>
      </div>
    </div>
