<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" 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"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">

</head>
<body>

<div class="container mt-3">
  <h2>按钮样式</h2>
  <button type="button" class="btn">基本按钮</button>
  <button type="button" class="btn btn-primary">主要按钮</button>
  <button type="button" class="btn btn-secondary">次要按钮</button>
  <button type="button" class="btn btn-success">成功</button>
  <button type="button" class="btn btn-info">信息</button>

  <button type="button" class="btn btn-light">浅色</button>
  <button type="button" class="btn btn-link">链接</button>      
</div>

</body>
</html>

按钮类可用于 <a>, <button>, 或 <input> 元素上:

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" 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"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">

</head>
<body>

<div class="container mt-3">
  <h2>按钮元素</h2>
  <a href="#" class="btn btn-info" role="button">链接按钮</a>
  <button type="button" class="btn btn-info">按钮</button>
  <input type="button" class="btn btn-info" value="输入框按钮">
  <input type="submit" class="btn btn-info" value="提交按钮"> 
</div>

</body>
</html>

按钮设置边框

Bootstrap 5 也可以设置按钮多边框，鼠标移动到按钮上添加突出到效果：

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" 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"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">
  <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="container mt-3">
  <h2>按钮设置边框</h2>
  <button type="button" class="btn btn-outline-primary">主要按钮</button>
  <button type="button" class="btn btn-outline-secondary">次要按钮</button>
  <button type="button" class="btn btn-outline-success">成功</button>
  <button type="button" class="btn btn-outline-info">信息</button>
  <button type="button" class="btn btn-outline-warning">警告</button>
  <button type="button" class="btn btn-outline-danger">危险</button>
  <button type="button" class="btn btn-outline-dark">黑色</button>
  <button type="button" class="btn btn-outline-light text-dark">浅色</button>
</div>

</body>
</html>

不同大小的按钮

Bootstrap 5 可以设置按钮的大小，使用 .btn-lg 类设置大按钮，使用 .btn-sm 类设置小按钮：

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" 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"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">
  <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="container mt-3">
  <h2>不同大小的按钮</h2>
  <button type="button" class="btn btn-primary btn-lg">大号按钮</button>
  <button type="button" class="btn btn-primary">默认按钮</button>
  <button type="button" class="btn btn-primary btn-sm">小号按钮</button>
</div>

</body>
</html>

块级按钮

通过添加 .btn-block 类可以设置块级按钮，.d-grid 类设置在父级元素中：

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" 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"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">
  <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="container mt-3">
  <p>通过添加 .btn-block 类可以设置块级按钮，.d-grid 类设置在父级元素中：</p>
  <div class="d-grid">
    <button type="button" class="btn btn-primary btn-block">按钮 1</button>
  </div>
</div>

</body>
</html>

如果有多个块级按钮，你可以使用用 .gap-* 类来设置：

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" 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"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">
  <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="container mt-3">
  <p>通过添加 .btn-block 类可以设置块级按钮，.d-grid 类设置在父级元素中：</p>
  <div class="d-grid gap-3">
    <button type="button" class="btn btn-primary btn-block">100% 宽度的按钮</button>
    <button type="button" class="btn btn-primary btn-block">100% 宽度的按钮</button>
    <button type="button" class="btn btn-primary btn-block">100% 宽度的按钮</button>
  </div>
</div>

</body>
</html>

激活和禁用的按钮

按钮可设置为激活或者禁止点击的状态。

.active 类可以设置按钮是可用的， disabled 属性可以设置按钮是不可点击的。 注意 <a> 元素不支持 disabled 属性，你可以通过添加 .disabled 类来禁止链接的点击。

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" 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"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">
  <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="container mt-3">
  <h2>按钮状态</h2>
  <button type="button" class="btn btn-primary">主要按钮</button>
  <button type="button" class="btn btn-primary active">点击后的按钮</button>
  <button type="button" class="btn btn-primary" disabled>禁止点击的按钮</button>
  <a href="#" class="btn btn-primary disabled">禁止点击的链接</a>
</div>

</body>
</html>

加载按钮

我们也可以设置一个正在加载的按钮。

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" 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"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="stylesheet">
  <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="container mt-3">
  <h2>加载按钮</h2>
  <p>按钮添加正在加载按钮:</p>
                                        
  <button class="btn btn-primary">
    <span class="spinner-border spinner-border-sm"></span>
  </button>

  <button class="btn btn-primary">
    <span class="spinner-border spinner-border-sm"></span>
