Bootstrap Buttons

有7种样式可以在Bootstrap中添加按钮。使用以下类来实现不同的按钮样式:

.btn-default
.btn-primary
.btn-success
.btn-info
.btn-warning
.btn-danger
.btn-link

Bootstrap 按钮示例: 指定七个样式

  <!DOCTYPE html>
<html lang="en">
  <head>
     <title>Job</title>
     <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"/>
  </head>
  <body>
    <h1>Button Example!</h1>
<button class="btn btn-default">default</button>
<button class="btn btn-primary">primary</button>
<button class="btn btn-danger">danger</button>
<button class="btn btn-success">success</button>
<button class="btn btn-info">info</button>
<button class="btn btn-warning">warning</button>
<button class="btn btn-link">Link</button>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
  </body>
</html>

注意: 在Bootstrap 4中添加了3种新按钮，在Bootstrap 3中添加了7种按钮。

<button type="button" class="btn btn-secondary">Secondary</button>
<button type="button" class="btn btn-dark">Dark</button>
<button type="button" class="btn btn-light">Light</button>
