移动端适配与响应式布局的区别
简单适配原理：
px自动转rem的方法：
1、sass less等
2、工程化手段
3、sublime安装插件
下载cssrem插件压缩包
sublime-首选项-浏览插件，打开插件目录packages ，把解压后的文件夹放进去
重启sublime，首选项-插件设置-cssrem-settings-user，复制这段话，然后保存
{
"px_to_rem": 40, //px转rem的单位比例，默认为40
"max_rem_fraction_length": 6, //px转rem的小数部分的最大长度。默认为6。
"available_file_types": [".css", ".less", ".sass",".html"]
//启用此插件的文件类型。默认为：[".css", ".less", ".sass"]
}
输入px时会出现下拉提示转rem，按tab键即可自动转换

function setremunit(){

var ratio=18.75;

var viewwidth=docel.getboundingclientrect().width || window.innerwidth;

}
})();
通用适配原理
简单适配原理存在的问题：
如果设置了1px的边框，在dpr=1时，边框为1；dpr=2时，边框为2；dpr=n时，边框为n
（注意，qq截取看不出，需要使用开发工具的截图capture screenshot，然后在ps里打开查看边框高度）
调试工具里可以添加可视化阴影，点击三个小点点
