手风琴--手风琴结构

手风琴最关键的部分，就是每个标题对应有一个内容，在Bootstrap框架中将这两个部分组合起来称为一个panel页板，如右边效果所示，他就有三个panel面板，将这三个面板组合在一起，就是一个面板组合 panel-group，也就是手风琴的结构。如：

<div class="panel-group" id="accordion">
    <div class="panel panel-default">
        <div class="panel-heading">
            <h4 class="panel-title"><a data-toggle="collapse" data-parent="#accordion" href="#collapseOne">标题一</a></h4>
        </div>
        <div id="collapseOne" class="panel-collapse collapse in">
            <div class="panel-body">标题一对应的内容</div>
        </div>
    </div>
    <div class="panel panel-default">
        <div class="panel-heading">
            <h4 class="panel-title"><a data-toggle="collapse" data-parent="#accordion" href="#collapseTwo">标题二</a></h4>
        </div>
        <div id="collapseTwo" class="panel-collapse collapse">
            <div class="panel-body">标题二对应的内容</div>
        </div>
    </div>
    <div class="panel panel-default">
        <div class="panel-heading">
            <h4 class="panel-title"><a data-toggle="collapse" data-parent="#accordion" href="#collapseThree">标题三</a></h4>
        </div>
        <div id="collapseThree" class="panel-collapse collapse">
            <div class="panel-body">标题三对应的内容</div>
        </div>
    </div>
</div>

简单点就是一个触发器和一个折叠区：

<button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#demo">触发器</button>
<div id="demo" class="collapse in">折叠区</div>
