在main.js中引入上述两个文件

解决移动端点击延迟的问题

html{
  touch-action:manipulation;
}

在项目中使用vw单位

参考文章

1. 安装依赖

npm install postcss-aspect-ratio-mini postcss-px-to-viewport postcss-write-svg postcss-cssnext cssnano cssnano-preset-advanced --save

2. 配置postcss.config.js

module.exports = {
  plugins: {
    autoprefixer: {},
    "postcss-px-to-viewport":{
      viewportWidth: 750, // 视窗的宽度，对应的是我们设计稿的宽度，一般是750
      viewportHeight: 1334, // 视窗的高度，根据750设备的宽度来指定，一般指定1334，也可以不配置
      unitPrecision: 3, // 指定`px`转换为视窗单位值的小数位数（很多时候无法整除）
      viewportUnit: 'vw', // 指定需要转换成的视窗单位，建议使用vw
      selectorBlackList: ['.ignore', '.hairlines'], // 指定不转换为视窗单位的类，可以自定义，可以无限添加,建议定义一至两个通用的类名
      minPixelValue: 1, // 小于或等于`1px`不转换为视窗单位，你也可以设置为你想要的值
      mediaQuery: false // 允许在媒体查询中转换`px`
    },
    "cssnano": { 
      preset: "advanced", 
      autoprefixer: false, 
      "postcss-zindex": false 
    }
  }
}
