<div style="border:1px solid red;width:300px;height:200px;"><div style="border: 1px solid black;background:pink"><h1 id="">2</h1></div></div>

那么这个div的背景色就会和第一个div的上边框重叠,
如果不设置这个border的话, 那么这个div的背景色就会和上面空出来一部分, 这部分的大小等于
这里margin-top设置的大小
这个怎么解释?。
我用ie9没这个情况,ie8和chrome都是这样
回复讨论(解决方案)
有chrome或者ie8的朋友可以把第二个div的border去掉, 看看区别

不过那次img src的图片不显示了不知道为什么
我用的是*{padding:0;margin:0;}
img{display:inline-block;}
谷歌一下margin 方面的资料好好看一下!!!
