Bootstrap code


Bootstrap allows you to display code in two ways:

  • The first is the <code> tag. If you want to display code inline, you should use the <code> tag.

  • The second type is the <pre> tag. If the code needs to be displayed as a separate block element or if the code has multiple lines, then you should use the <pre> tag.

Please make sure that when you use the <pre> and <code> tags, the opening and closing tags use the unicode variants: < and >.

Let's take a look at the following example:

Instance

<!DOCTYPE html>
<html>
<head>
   <title>Bootstrap 实例 - 代码</title>
   <link href="http://libs.baidu.com/bootstrap/3.0.3/css/bootstrap.min.css" rel="stylesheet">
   <script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
   <script src="http://libs.baidu.com/bootstrap/3.0.3/js/bootstrap.min.js"></script>
</head>
<body>

<p><code><header></code> 作为内联元素被包围。</p>
<p>如果需要把代码显示为一个独立的块元素，请使用 <pre> 标签：</p>
<pre>
   <article>
      <h1>Article Heading</h1>
   </article>
</pre>

</body>
</html>
