爆牙兄的CSS题目解答
其实这道题我年初就做出来过。今天想看看自己这半年来CSS有多少进步,所以又找到这题,写了一下代码。
之前的代码跟现在的代码相比,解决思路是一样的,不同的是,
- 时间短了,这次我差不多用了2个小时(其中包括一些图片截取工作),而以前从出第一个结果到后面为了兼容IE6,搞了差不多4个小时。
- 代码规整多了,margin、padding不再那么不清晰
- 为了兼容IE6使用的HACK少了,只使用了2次 !important,可以说成功绕过了一些问题。最可喜的是,这种绕过是一种很自然的绕过,我甚至没有碰到什么兼容性问题,不需要花时间改变思路。
HTML代码部分如下:

这段不能动的泡泡HTML代码中,适用了“微格式”,可惜到现在我也没有去深入研究它。
