第一次写博客，语言组织什么的不够成熟。可能写的不太好，有什么不足之处，希望可以提出并指导我一下，谢谢
最近在学习移动端。所以找了京东移动端http://m.jd.com/ 来模仿。
京东移动端开始

在这里base.css样式就在这边写了。
一些个人的感受：
1.尽量使用语义化标签
2.在一个整体的盒子里面在包裹一个大盒子。里面在写上自己元素，方便整体的移动。
3.把一些公共的以及常用的样式，单独设置样式。这样需要某一样式直接加类名即可，js中使用更加方便，直接添加移除类名即可。减少css代码冗余
4.css样式想写好真的不简单，看着简单的布局，写的时候就是各种坑
首页中有焦点轮播图和京东快报处的滚动以及秒杀倒计时就明天再写吧
希望可以给大家带来一点点帮助
