CSS应用在网页设计中越来越重要，Web2.0中涉及到比较的网页元素包括DIV和CSS两种，由于可以控制页面元素的浮动效果，所以在设计者来说，可以控制数据显示顺序。DIV与Table的区别在于显示模式，在网络速度比较慢的情况下，数据显示速度将在视觉效果上决定用户对网络速度的了解。现在有比较多说法是，采用DIV+CSS能提高速度的原理其实是具体的显示效果，真实的网络传输速度将不会因为采用什么样子的元素而改变。
CSS is important. And it is being used more and more often. Cascading Style Sheets offer many advantages you don’t have in table-layouts – and first of all a strict separation between layout, or design of the page, and the information, presented on the page. Thus the design of pages can be easily changed, just replacing a css-file with another one. Isn’t it great? Well, actualy, it is.
