Kuwarci ko XHTML?

如何将你的网站升级至 XHTML ？

为了将站点从 HTML 转换为 XHTML，你首先应该熟悉前几章讲解的 XHTML 语法规则。

下面讲解具体的步骤。

添加文件类型声明

将下面的文件类型声明添加至每页的首行：

<!DOCTYPE html PUBLIC
"-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

注意：本站 (codew3c) 使用的是严格的 DTD。不过使用过渡的 DTD 也是个不错的选择，因为对于大多数入门的开发人员来说，严格的 DTD 可能显得“太严格了”。

Why did we not use Tidy? When we started creating this website, we were very familiar with XHTML. At that time, we already knew to use lowercase tags and to quote attributes. So during the website testing process, we simply tested through W3C's XHTML validator and corrected a few errors. More importantly, we have learned a lot about writing Tidy-style HTML code.
