图片红色长方形表示浏览器显示的部分，
图片一共三排（每排div都是通过第一个div进行浮动，第二排和第三排调了外边距）div组成，
我想在不同分辨率荧幕下的显示效果相同，请问该怎么实现，小白实在不懂，搞了一下午也没头绪，希望大家帮帮忙。
回复讨论(解决方案)
宽高可以设置为百分比的值，如width;100%; 这个百分比是按照屏幕大小算的，百分之百就是屏幕的宽高。
显示效果相同 这句话太模糊了
比如手机 横过来 和竖过来 你也要显示一模一样的？
一般情况下 我们更喜欢 自然排列
只要定义好 div的宽高 后面 float：left就自己撑高度啊
复杂情况下 我们要根据不同的显示屏幕大小 定义不同的 div的宽高
最最简单的 你页面什么多余的不要写 只要写死红色div的宽度就可以了
不同分辩率有不同的宽度，只要让你的设计在不同宽度中div自动浮动
