// 1.安装依赖 npm install lib-flexible --save-dev npm i postcss-px2rem --save // 2.在main.js内引用 import 'lib-flexible' // 3.在vue.config.js内配置 // 其中的remUnit是根据设计稿自定义,设计稿尺寸/10 module.exports = { lintOnSave: false, configureWebpack: {}, chainWebpack: () => {}, css: { loaderOptions: { css: {}, postcss: { plugins: [ require("postcss-px2rem")({ remUnit: 136.6 }) ] } } } }; 4.修改flexible.js配置 node_moudles/lib-flexible/flexible.js function refreshRem(){ var width = docEl.getBoundingClientRect().width; if (width / dpr > 540) { // width = 540 * dpr; // 540修改为width width = width * dpr; } var rem = width / 10; docEl.style.fontSize = rem + 'px'; flexible.rem = win.rem = rem; }
