以下代码加入区域  
<div id="tic">  
<h1>什么是ASP？</h1>  
<p>  
Ａｃｔｉｖｅ　Ｓｅｒｖｅｒ　Ｐａｇｅｓ（ASP，活动服务器页面）就是一个编程环境，在其中，可以  
混合使用HTML、脚本语言以及组件来创建服务器端功能强大的Internet应用程序。 </p>  
<p>  
 如果你以前创建过一个站点，其中混合了HTML、脚本语言以及组件，你就可以在其中加入ASP程序代码。  
通过在HTML页面中加入脚本命令，你可以创建一个HTML用户界面，并且，还可以通过使用组件包含一些商  
业逻辑规则。</p>  
<p>  
组件可以被脚本程序调用，也可以由其他的组件调用。  
</p>

<h2>什么是 ASP.NET？</h2>  
<p>  
ASP.NET 是建立在公共语言运行库上的编程框架，可用于在服务器上生成功能强大的 Web 应用程序。  
</p>  
<p>  
与以前的 Web 开发模型相比，ASP.NET 提供了数个重要的优点：增强的性能、世界级的工具支持、威力  
和灵活性、简易性、可管理性、可缩放性和可用性、自定义性和扩展性、安全性。  
</p>

<h2>什么是PHP？</h2>  
<p>  
PHP 是一种用来制作动态网页的服务器端脚本语言。你通过PHP和HTML创建页面。当访问者打开网页时，  
服务器端便会处理 PHP 指令，然后把其处理结果送到访问者的浏览器上面，就好像 ASP 或者是   
ColdFusion 一样。然而，PHP 跟 ASP 或 ColdFusion 不一样的地方在于，它是跨平台的开放源代码。
