xHTML

代码说明：

  一个HTML文件是一页文字信息，就象一封电子邮件或一个word字处理文档，而且实际上你完全可以使用Word字处理软件来编写一个HTML网页。你也可以通过其它字处理软件编写文本文件，网络浏览器只能处理文本信息。 (An HTML file is a text message, an email or a word as word processing documents, and in fact you to write a complete HTML page can use Word word processing software. You can also write a text file by other word processing software, web browsers can handle only text messages.)
