什么是样式表： CSS 是 Cascading Style Sheet 的缩写。译作「层叠样式表单」。是用于(增强)控制网页样式并允许将样式信息与网页内容分离的一种标记性语言。 如何将样式表加入您的网页： 你可以用以下三种方式将样式表加入您的网页。而最接近目标的样式定义优先权越高。高优先权样式将继承低优先权样式的未重叠定义但覆盖重叠的定义。例外请参阅 !important 声明。 链入外部样式表文件 (Linking to a Style Sheet) 你可以先建立外部样式表文件（.css），然后使用HTML的link对象。示例如下： &lt;head&gt; &lt;title&gt;文档标题&lt;/title&gt; &lt;link rel=stylesheet href="http://www.dhtmlet.com/dhtmlet.css" type="text/css"&gt; &lt;/head&gt;

本人一直使用的序列号,分享出来欢迎下载 SQL Server SQL Server 是一个关系数据库管理系统。它最初是由Microsoft Sybase 和Ashton-Tate三家公司共同开发的，于 Microsoft SQL Server Microsoft SQL Server 1988 年推出了第一个OS/2 版本。在Windows NT 推出后，Microsoft与Sybase 在SQL Server 的开发上就分道扬镳了，Microsoft 将SQL Server 移植到Windows NT系统上，专注于开发推广SQL Server 的Windows NT 版本。Sybase 则较专注于SQL Server在UNIX 操作系统上的应用。
