autoprefixer VS rollup-plugin-postcss

Do you use Autoprefixer? https://github.com/postcss/autoprefixer

Simple, fast, and a little bit opinionated, Eleventy Plus Vite features Eleventy 2.0.0-canary, the new Eleventy 2.0 Dev Server with live reload, Vite 3.0 as Middleware in Eleventy Dev Server (using eleventy-plugin-vite), build output post-processing by Vite (with Rollup), CSS/Sass post-processing with PostCSS including Autoprefixer and cssnano, a custom CSS/Sass structure, basic fluid typography based on Utopia, dark mode support, an RSS feed, XML sitemap, and — to top it off — perfect scores on Lighthouse.

w/ postcss-preset-env(v7.8.3): convert modern CSS into something most browsers can understand, determining the polyfills you need based on your targeted browsers or runtime environments. It takes the support data that comes from MDN and Can I Use and determine from a browserlist whether those transformations are needed. It also packs Autoprefixer within and shares the list with it, so prefixes are only applied when you're going to need them given your browser support list.

As others have said, you need to normalize. Also, you may need something like autoprefixer if you're using styles that have different vendor prefixes. https://github.com/postcss/autoprefixer

Mmm maybe it's not gap then, maybe it's some other property. Maybe autoprefixer could help. Or polyfills, as other user suggested.

Of course, we have great tooling for that: Autoprefixer, PostCSS and Stylelint for CSS transformation, Babel and Webpack for JavaScript transpilation and bundling, ESLint for code analysis, and many others.

Bulma uses autoprefixer to make (most) Flexbox…

The React Library Builder supports both SCSS and CSS out of the box, so you can style your components as you normally would. If you want to use CSS modules, you can refer to the rollup-plugin-postcss documentation for more information.

import { nodeResolve } from "@rollup/plugin-node-resolve"; import postcss from "rollup-plugin-postcss"; import copy from "rollup-plugin-copy"; export default [ { input: "src/js/combine.js", output: { file: "src/js/minified/index.bundle.js", sourcemap: false, } plugins: [ nodeResolve(), postcss({ extract: true, // no way to move output to another folder https://github.com/egoist/rollup-plugin-postcss/issues/250 minimize: true, }), copy({ targets: [ { src: "src/js/minified/index.bundle.css", dest: "src/styles/minified", rename: "fonts.bundle.css", }, ], verbose: true, hook: "writeBundle", }) ], } ];

To process Less files we will use PostCSS, which is a JavaScript build tool for CSS, Less, and other CSS preprocessors. It also comes with a built-in minifier. We can add it to the project with a Rollup plugin:
