某些字符在HTML中保留，在HTML文档中使用时具有特殊含义。例如，您不能在HTML文本中使用大于或小于标记或尖括号，因为浏览器会以不同方式对待它们，并尝试绘制与HTML标记相关的含义。

HTML处理器必须支持下表中列出的以下五个特殊字符。

符号	描述	实体名称	数字代码
"	quotation mark	"	"
'	apostrophe	'	'
&	ampersand	&	&
<	less-than	<	<
>	greater-than	>	>

例子 (Example)

如果你想将

写为代码，那么你必须写如下 -

<!DOCTYPE html>
<html>
   <head>
      <title>HTML Entities</title>
   </head>
   <body>
      <div id = "character">
   </body>
</html>

HTML 4.0中还有一长串特殊字符。为了使它们出现在您的文档中，您可以使用数字代码或实体名称。例如，要插入版权符号，您可以使用以下任一项 -

© 2007
or
© 2007
