技术分享一开始毫无头绪,看了评分最高的团队的代码,觉得很棒。

他们的代码 我的代码

思考了一下有没有优化的方法,发现权衡之下并没有。

他们的代码使用box-sizing: border-box来解决了20px间距的问题,使用伪元素来清除浮动(我打算把父级元素改为overflow:hidden来解决,其实差不多,而且据说overflow有一些坑)

对于类的命名,我选择了张鑫旭对类名的命名规律。(感觉在于大的工程中会比较有用,然而这是一个小任务)

后来想到还有一种方法可以不使用浮动,就是将outer的display设置为inline-block,不过缩进有些辣眼睛,相较之下还是原作者的方法比较好,使用这样的缩进的原因请看css table-cell自动补充元素问题
