Blog post: show where postcss-mixins goes in the config - #58
Merged
Conversation
The PostCSS setup post told readers to install postcss-mixins if they want mixins, but neither config block ever showed the plugin in the plugins array. It also claimed this site's config is "exactly the file above", when the repo's own postcss.config.cjs includes postcss-mixins. Add a commented opt-in line to both config blocks, state the plugin order rule (import, mixins, preset-env, matching build-css.mjs), and correct the sentence about the site's own config.

What changed
The PostCSS setup post (postcss-setup-for-mcss.mdx) told readers to
npm install -D postcss-mixinsif they want mixins, but neither of its twopostcss.config.cjscode blocks ever showed the plugin in the plugins array. Readers who opted in were left to guess where it goes.// require("postcss-mixins"),line at the top of the plugins array, with a note that it must run before preset-env.postcss-importand preset-env, and the "Order is not a style preference" paragraph now states the full rule: import, then mixins, then preset-env. This matches the repo's ownpostcss.config.cjsandsrc/tools/build-css.mjs.Why
The docs page
start.mdxsays mixins "require a PostCSS plugin to work" and links to this post, so the post should actually show the wiring. Without it, the post's "exactly the file above" sentence also contradicted the repo's real config.Notes for review
Prose-only change to one blog post; no code or config touched. Plugin order was verified against
