Bootstrap3组件

Glyphicons

感谢Glyphicons的工作人员的慷慨, 允许BT的使用者免费使用添加一个有情连接http://glyphicons.com/

在需要用到字体图标的地方添加以下代码

<span class="glyphicon glyphicon-search"></span>

当然不要忘记图标和文本之前要添加一个空格这样显示会更好

下拉菜单

    <div class="dropdown">        <button type="button" class="btn btn-primary dropdown-toggle" id='drop1' data-toggle="dropdown">drop <span class="caret"></span></button>        <ul class="dropdown-menu" role="menu" aria-labelledby="drop1">            <li><a href="">asda</a></li>            <li><a href="">aaaa</a></li>            <li><a href="">wwww</a></li>        </ul>    </div>

这里需要注意的是给button 添加dropdown-toggle类还要添加data-toggle属性为dropdown

按钮组

实现2边都是圆角然后中间按钮和2边的都是紧挨的

    <div class="btn-group">        <button type="button" class="btn">11</button>        <button type="button" class="btn">22</button>        <button type="button" class="btn">33</button>    </div>

可以添加btn-group-lg 省去了给每一个按钮添加lg 这样整个按钮组都变大了

如果想让按钮不是水平排列而是垂直只要添加btn-group-vertical就OK了

导航条

navbar-fixed-top导航条固定在顶部

navbar-fixed-bottom固定在底部

这2个都需要你给body 添加margin 来覆盖掉默认的不然导航条会遮盖主体内容

body { padding-top: 70px; }

下面引用BT官方文档里的一段代码来演示BT的导航条是可以响应式的导航条.当你在手机上浏览的时候导航条会被折叠条目会在右侧的一个小图标中, 你点击图标会出来

静止在顶部navbar-static-top

反色navbar-inverse

当你屏幕宽度变小时候会发生这个情况

右侧的3横条所有导航里的条目就隐藏在这里

   <nav class="navbar navbar-default navbar-fixed-top navbar-inverse" role="navigation">        <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">                    <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</a>                    </li>                    <li><a href="#">Link</a>                    </li>                    <li class="dropdown">                        <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <span class="caret"></span></a>                        <ul class="dropdown-menu" role="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>                <form class="navbar-form navbar-left" role="search">                    <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">Dropdown <span class="caret"></span></a>                        <ul class="dropdown-menu" role="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>                        </ul>                    </li>                </ul>            </div>            <!-- /.navbar-collapse -->        </div>        <!-- /.container-fluid -->    </nav>

分页

   <ul class="pagination">        <li><a href="">«</a></li>        <li><a href="">1</a></li>        <li><a href="">2</a></li>        <li><a href="">3</a></li>        <li><a href="">»</a></li>    </ul>

可以用pagination-lg pagination-sm来控制大小

巨幕

    <div class="container">        <div class="jumbotron">            <h1>Hello CSDN</h1>            <p>This is a page for BT</p>        </div>    </div>

这主要用于主体部分展示主要展品信息较为醒目

警告框

<div class="alert alert-success alert-dismissible"><button type="button" class="close" data-dismiss="alert"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>  <strong>Warning!</strong> You finished the mission</div>

alert-dismissible 的意思是带有关闭按钮的警告框

进度条

        <div class="progress">        <div class="progress-bar" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%;">            <span>60% Complete</span>        </div>    </div>        <div class="progress">        <div class="progress-bar progress-bar-success" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%;">            <span>60% Complete</span>        </div>    </div>        <div class="progress">        <div class="progress-bar progress-bar-info" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%;">            <span>60% Complete</span>        </div>    </div>        <div class="progress">        <div class="progress-bar progress-bar-warning" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%;">            <span>60% Complete</span>        </div>    </div>        <div class="progress">        <div class="progress-bar progress-bar-danger" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%;">            <span>60% Complete</span>        </div>    </div>

带有不同颜色进度条如果不想显示进度的数字可以给span添加sr-only类

想添加条纹效果得进度条添加类progress-bar-striped

列表组

        <div class="list-group">            <a href="" class="list-group-item active">home</a>            <a href="" class="list-group-item">contact</a>            <a href="" class="list-group-item">help</a>            <a href="" class="list-group-item">you</a>        </div>

可以给被禁用的条目添加 disabled

还有一些其他的组件, 不是很常用, 比较多难于记忆, 请用到的同学去查文档就可以了.
