flex实战京东页面

京东app页面

• rest.css全局初始化文件，媒体查询文件
• 通过impoart公共文件
• @media screen and (min-width: 480px)— font-size: 12px;
• @media screen and (min-width: 640px)— font-size: 14px;
• @media screen and (min-width: 720px)— font-size: 16px;
• 通过媒体查询改变html文字大小，实现全局响应式
• header，footer文件单独书写引入，模块通用，使用用绝对定位，z-inde属性等排在最上层

  页面效果
