移动手机专题rem布局实践+主要代码

HTML开头部分

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />   
<meta name="viewport" content="width=device-width; initial-scale=1.0; minimum-scale=1.0; maximum-scale=1.0; user-scalable=no;"/>  //移动必加样式

主要代码为CSS部分

html { font-size: 62.5%;}     //
body {font-size: 1.2rem; width: 32rem;} //定义body大小，body为居中内容部分

因为设计图是640px的，而且我下面的css定义的是640px时(font-size：125%) 可得出1rem=20px

以下为CSS中字体随屏幕大小变化规律，代码很长，复制进去你的代码即可
