Bootstrap4 按鈕組

2018-05-28 15:27 更新

在上篇文章中，我們已經(jīng)為大家介紹了單個(gè)按鈕樣式的設(shè)置，詳情請(qǐng)參考：Bootstrap4 按鈕

但是在Bootstrap 4中，除了單個(gè)按鈕外，還允許我們將按鈕放在同一行上，組成按鈕組。


按鈕組創(chuàng)建：

我們可以在 <div> 元素上添加 .btn-group 類來(lái)創(chuàng)建按鈕組。

實(shí)例：

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap 實(shí)例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank" >

</head>
<body>
<div class="container">
  <h2>按鈕組</h2>
  <p> .btn-group 類用于創(chuàng)建按鈕組:</p>
  <div class="btn-group">
    <button type="button" class="btn btn-primary">Apple</button>
    <button type="button" class="btn btn-primary">Samsung</button>
    <button type="button" class="btn btn-primary">Sony</button>
  </div>
</div>
</body>
</html>

提示: 我們可以使用 .btn-group-lg、btn-group-sm、btn-group-xs 類來(lái)設(shè)置按鈕組的大小。

<div class="container">
  <h2>按鈕組大小</h2>
  <p>我們可以使用 .btn-group-lg|sm|xs 類來(lái)設(shè)置按鈕組的大小。</p>
  <h3>大按鈕:</h3>
  <div class="btn-group btn-group-lg">

  </div>

垂直按鈕組

可以使用 .btn-group-vertical 類來(lái)創(chuàng)建垂直的按鈕組：

<!DOCTYPE html>

<head>
  <title>Bootstrap 實(shí)例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">

  </div>

內(nèi)嵌按鈕組及下拉菜單

我們可以在按鈕組內(nèi)設(shè)置下拉菜單：

<!DOCTYPE html>
