Use when reviewing stylesheets, component styles, and responsive behavior related to Minify all CSS files. Check the rendered layout across breakpoints and interaction states before proposing a fix.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Minify all CSS files Unminified CSS wastes bandwidth with whitespace, comments, and verbose syntax—minification delivers the same styles in significantly fewer bytes. ## Quick Reference - Enable minification in build tool (Vite, webpack, etc.) - Use cssnano or lightningcss for PostCSS pipelines - Typical reduction: 20-40% file size savings - Combine with Gzip/Brotli for maximum compression ## Check Verify that all CSS files are minified in production to reduce file size, eliminate whitespace, and improve page load performance. ## Fix Set up CSS minification in your build process using tools like cssnano, CleanCSS, or built-in framework minification to compress CSS files. ## Explain Explain how CSS minification improves website performance by reducing file sizes, decreasing bandwidth usage, and speeding up page load times. ## Code Review Review stylesheets, component styles, and responsive states related to Minify all CSS files. Flag exact selectors, declarations, or breakpoints that violate the rule in the rendered UI. --- For full implementation details, code examples, and framework-specific guidance, see `references/rule.md`. …

How to install
mdr add thedaviddias/front-end-checklist/css-minification@sha256:b6d4282318bc1500The line at the top of this page pins the label git:20261004.4b0ddb9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
