由于
viewport单位得到众多浏览器的兼容，lib-flexible这个过渡方案已经可以放弃使用，不管是现在的版本还是以前的版本，都存有一定的问题。建议大家开始使用viewport来替代此方。
npm i -S amfe-flexible
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no">
<script src="./node_modules/amfe-flexible/index.js"></script>You can inline this file with inline-source.
Use postcss-adaptive.
