HTML 文本格式化实例
（我不知道为什么“正常显示文本”这几个字不用加标签，虽然它有在

<html><body><b>文本为黑体<br /></b><strong>文本表示强调，强于em，应谨慎使用<br /></strong><big>文本显示大号字体<br /></big><em>表示强调，谨慎使用<br/></em><i>文本以斜体标识<br /></i><small>文本显示小号字体<br /></small>正常显示文本<sub>下脚标</sub><br />正常显示文本<sup>上脚标</sup></body></html>
运行效果：(注：第一排改为：文本黑体)
预文本格式示例：
<html><body><pre class="brush:php;toolbar:false">预格式文本就是保留了 空格以及换行
pre 标签很适合用来装逼：
