Bootstrap按钮组将一系列按钮组合在一行中。
要创建按钮组，在一个<div>元素中封装一系列按钮，并在其上应用.btn-group类。

</html>按钮工具栏
我们可以将按钮组合在一起来创建按钮工具栏。要创建按钮工具栏，要在<div>元素中封装按钮组，并在其上应用.btn-toolbar类。

<div class="bs-example">
<div class="btn-toolbar">
<div class="btn-group">

<button type="button" class="btn btn-primary">3</button>
<button type="button" class="btn btn-primary">4</button>
</div>
<div class="btn-group">
<button type="button" class="btn btn-primary">5</button>
<button type="button" class="btn btn-primary">6</button>
<button type="button" class="btn btn-primary">7</button>
</div>
<div class="btn-group">
<button type="button" class="btn btn-primary">8</button>
</div>
</div>
</div>
</body>
</html>按钮组的高度
我们可以在按钮组上应用相关大小的类，如.btn-group-lg，.btn-group-sm或.btn-group-xs来创建更大或更小的按钮组。

<style type="text/css">

<body>
<div class="bs-example">
<div class="btn-toolbar">
<div class="btn-group btn-group-lg">
<button type="button" class="btn btn-primary">Left</button>
<button type="button" class="btn btn-primary">Middle</button>
<button type="button" class="btn btn-primary">Right</button>
</div>
</div>
<br>
<div class="btn-toolbar">
<div class="btn-group">
<button type="button" class="btn btn-primary">Left</button>
<button type="button" class="btn btn-primary">Middle</button>
<button type="button" class="btn btn-primary">Right</button>
</div>
</div>
<br>
<div class="btn-toolbar">
<div class="btn-group btn-group-sm">
<button type="button" class="btn btn-primary">Left</button>
<button type="button" class="btn btn-primary">Middle</button>
<button type="button" class="btn btn-primary">Right</button>
</div>
</div>
<br>
<div class="btn-toolbar">
<div class="btn-group btn-group-xs">
<button type="button" class="btn btn-primary">Left</button>
<button type="button" class="btn btn-primary">Middle</button>
<button type="button" class="btn btn-primary">Right</button>
</div>
</div>
</div>
</body>
</html>在组中对齐按钮
我们可以通过应用一个额外的类.btn-group-justified到.btn-group基类，来使一组按钮伸展到相同的大小以跨越其父类的整个宽度。
<!DOCTYPE html>
<html lang="en">
<head>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css">
<style type="text/css">
.bs-example{
margin: 20px;
}
</style>
</head>
<body>
<div class="bs-example">
<div class="btn-group btn-group-justified">
<a href="#" class="btn btn-primary">Left</a>
<a href="#" class="btn btn-primary">Middle</a>
<a href="#" class="btn btn-primary">Right</a>
</div>
</div>
</body>
</html>对齐按钮组
要使用<button>元素调整按钮组，请将每个按钮单独封装在.btn-group类中。
<!DOCTYPE html>

<div class="btn-group">
<button type="button" class="btn btn-primary">Left</button>
</div>
<div class="btn-group">

</div>
<div class="btn-group">
<button type="button" class="btn btn-primary">Right</button>
