使用环境
| 名称 | 版本 |
|---|---|
| vue | 3.2.13 |
| vue-cli | 5.x |
| webpack | 5.x |
| nodejs | 16.15 |
| postcss-px-to-viewport | ^1.1.1 |
安装
npm install postcss-px-to-viewport --save-dev yarn add postcss-px-to-viewport --save-dev pnpm add postcss-px-to-viewport --save-dev
如果devserver正在运行，安装完成以后记得重启devserver。
配置
在项目根目录下创建 postcss.config.js 文件，并填入一下内容：
module.exports = {
plugins: {
// ...
'postcss-px-to-viewport': {
// options
unitToConvert: "px",
viewportWidth: 1920,
viewportHeight:1080,
unitPrecision: 3,
propList: [
"*"
],
viewportUnit: "vw",
fontViewportUnit: "vw",
selectorBlackList: [],
minPixelValue: 1,
mediaQuery: false,
replace: true,
exclude: /(\/|\\)(node_modules)(\/|\\)/,
}
}
}重新运行，打开浏览器查看属性值已经变为vw计算，就是这么简单。
