本文給大家介紹按鈕標簽的實例代碼，具體內容如下：

通過將按鈕類添加到 <a>,  <button>,  <input> 來實現按鈕樣式

<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">

僅僅 <button> 適用于導航條以及導航條控件

如果 <a> 被作為按鈕使用而不是鏈接, 請注意添加 role="button"

高度推薦使用 <button>
