1、符合W3C标准。微软等公司均为W3C支持者。这一点是最重要的,因为这保证您的网站不会因为将来网络应用的升级而被淘汰。2、支持浏览器的向后兼容,也就是无论未来的浏览器大战,胜利的是IE7或者是火狐,您的网站都能很好的兼容。
3、搜索引擎更加友好。相对与传统的table,
采用DIV+CSS技术的网页,对于搜索引擎的收录更加友好。
4、样式的调整更加方便。内容和样式的分离,使页面和样式的调整变得更加方便。
现在YAHOO,MSN等国际门户网站,网易,新浪等国内门户网站,和主流的WEB2.0网站,均采用DIV+CSS的框架模式,更加印证了DIV+CSS是大势所趋。
5、CSS的极大优势表现在简洁的代码,对于一个大型网站来说,可以节省大量带宽,而且众所周知,搜索引擎喜欢清洁的代码。
6、表现和结构分离,在团队开发中更容易分工合作而减少相互关联性
