1、超大屏幕
<!-- 响应式 --><div class="container"><div class="row"><div class="col"><div class="jumbotron"><h1 class="display-4">Hello, world!</h1><!-- display-4：标题 --><p class="lead">This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.</p><hr class="my-4"><p>It uses utility classes for typography and spacing to space content out within the larger container.</p><a href="#" class="btn btn-primary btn-lg">Learn more</a></div></div></div></div><!-- 全屏显示：不放在container里 --><div class="jumbotron jumbotron-fluid"><div class="container-fluid"><!-- 栅格系统：container-fluid？？ --><h1 class="display-4">Fluid jumbotron</h1><p class="lead">This is a modified jumbotron that occupies the entire horizontal space of its parent.</p></div></div>
2、列表组原型
<div class="row mt-5">
<div class="col">
<ul class="list-group">
<li class="list-group-item">red</li>
<li class="list-group-item active">green</li><!-- 选中状态 -->
<li class="list-group-item">blue</li>
<li class="list-group-item disabled">yellow</li><!-- 禁用选项 -->
<li class="list-group-item">pink</li>
</ul>
</div>
</div>
3、列表组按钮和a标签
<div class="row mt-5">
<div class="col">
<div class="list-group">
<a href="#" class="list-group-item list-group-item-action">red</a>
<a href="#" class="list-group-item list-group-item-action active">green</a>
<a href="#" class="list-group-item list-group-item-action">blue</a>
<button class="list-group-item list-group-item-action" disabled>yellow</button>
<button class="list-group-item list-group-item-action">pink</button>
</div>
</div>
<div class="col">
<ul class="list-group list-group-flush">
<li class="list-group-item">red</li>
<li class="list-group-item">green</li>
<li class="list-group-item">blue</li>
<li class="list-group-item">yellow</li>
<li class="list-group-item">pink</li>

<li class="list-group-item list-group-item-light">添加背景色</li>
<li class="list-group-item list-group-item-dark">添加背景色</li>
</ul>
</div>
<!-- hover效果 -->
<div class="col">
<ul class="list-group">
<li class="list-group-item list-group-item-action list-group-item-primary">有hover状态的</li>
<li class="list-group-item list-group-item-action list-group-item-secondary">有hover状态的</li>
