本文给大家介绍按钮标签的实例代码，具体内容如下：
通过将按钮类添加到 <a>, <button>, <input> 来实现按钮样式
<a class="btn btn-default" href="#" rel="external nofollow" role="button">Link</a><button class="btn btn-default" type="submit">Button</button><input class="btn btn-default" type="button" value="Input"><input class="btn btn-default" type="submit" value="Submit">
仅仅 <button> 适用于导航条以及导航条控件
如果 <a> 被作为按钮使用而不是链接, 请注意添加 role="button"
高度推荐使用 <button>
选项
<!-- Standard button --><button type="button" class="btn btn-default">Default</button><!-- Provides extra visual weight and identifies the primary action in a set of buttons --><button type="button" class="btn btn-primary">Primary</button><!-- Indicates a successful or positive action --><button type="button" class="btn btn-success">Success</button><!-- Contextual button for informational alert messages --><button type="button" class="btn btn-info">Info</button><!-- Indicates caution should be taken with this action --><button type="button" class="btn btn-warning">Warning</button><!-- Indicates a dangerous or potentially negative action --><button type="button" class="btn btn-danger">Danger</button><!-- Deemphasize a button by making it look like a link while maintaining button behavior --><button type="button" class="btn btn-link">Link</button>
尺寸
通过添加 .btn-lg , .btn-sm , .btn-xs 来实现尺寸
<p> <button type="button" class="btn btn-primary btn-lg">Large button</button> <button type="button" class="btn btn-default btn-lg">Large button</button></p><p> <button type="button" class="btn btn-primary">Default button</button> <button type="button" class="btn btn-default">Default button</button></p><p> <button type="button" class="btn btn-primary btn-sm">Small button</button> <button type="button" class="btn btn-default btn-sm">Small button</button></p><p> <button type="button" class="btn btn-primary btn-xs">Extra small button</button> <button type="button" class="btn btn-default btn-xs">Extra small button</button></p>
通过添加 .btn-block 来实现块级按钮
<button type="button" class="btn btn-primary btn-lg btn-block">Block level button</button><button type="button" class="btn btn-default btn-lg btn-block">Block level button</button>
激活状态
<button type="button" class="btn btn-primary btn-lg active">Primary button</button><button type="button" class="btn btn-default btn-lg active">Button</button>
禁用状态
