1.下载lib-flexible
npm i lib-flexible --save
2.在index.html中
<html data-dpr = '1'>
在common.css中写
html {
font-size: 10vw;
}
3.设置meta标签
<meta name="viewport" content="width=device-width, initial-scale=1.0">
4.安装px2rem-loader
npm install px2rem-loader
5.配置px2rem-loader
在build文件中找到util.js，将px2rem-loader添加到cssLoaders中，如:
const cssLoader = {
loader: 'css-loader',
options: {
minimize: process.env.NODE_ENV === 'production',
sourceMap: options.sourceMap
}
}
const px2remLoader = {
loader: 'px2rem-loader',
options: {
remUnit: 75
}
}
同时，在generateLoaders方法中添加px2remLoader
function generateLoaders (loader, loaderOptions) {
const loaders = [cssLoader,px2remLoader]
if (loader) {
loaders.push({
loader: loader + '-loader',
options: Object.assign({}, loaderOptions, {
sourceMap: options.sourceMap
})
})
}
6.重启，一切ok~
npm run dev
