autoprefixer VS rollup-plugin-terser

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…

This next one will help us reduce final bundle size by minifying the generated code. It's called rollup-plugin-terser and uses terser under the hood to minify the code.

Generating a bundle that has many dependencies, from our code or third-party packages, will result in a large JavaScript file. To optimize the bundle it is useful to integrate Terser into our build process. What Terser does is it removes comments, shorten variables names, cut whitespaces and minify our code to make it the shortest possible. Again Terser can be integrated with Rollup using a plugin:
