你试图让你的HTML执行CSS设计的任务。你的JSP构建它认为HTML将呈现的外观，并将其转发给用户。因此，用户永远不会看到JSP，只会看到一个HTML页面。因此，当你使用特殊标签时，它们是在服务器上执行并转发给用户。

英文:
Your trying to make your HTML do what CSS was designed to do. Your JSP builds what it thinks the HTML will look like and forwards that to the user. Thus the user never sees the JSP only an HTML page. So when you use the special tags they are done on the server and forwarded to the user.
