How CSS is written in this repo — every value comes from a design token, one component gets one name across both surfaces, and the five theme lints decide what ships. Covers the token layer and the half-finished spacing migration, modern syntax that is actually safe here (cascade layers and container queries are Baseline widely; anchor positioning is not), keeping specificity flat with :where() instead of !important, component structure and shared partials, DRY across report.css and panel.css…
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
# Writing CSS here Two stylesheets, ~2,000 lines, concatenated by Python after a generated token layer into one inline `<style>`. Neither is valid alone — both reference custom properties they do not declare, and `panel.css` on its own fails the `color-scheme` check. Assembly, splitting and the byte pins belong to `refactoring-the-assembled-ui`; this is how you write a rule. ## Tokens are the language `_ui_theme.py` declares **78 custom properties** on `:root` (58 of them user-themable) and prepends them to both sheets. The discipline is already strong — `panel.css` uses `var(--…)` 605 times against 13 raw hex literals, `report.css` 429 against 8 — and it is the thing to protect. - **Never write a raw colour.** If a role does not exist, add the token; do not inline a hex. - **The spacing migration is half done, so finish it rather than widening it.** `--sp-0` … `--sp-7` exist and are used throughout the usage sections, yet `.5rem`, `.25rem`, `.75rem`, `1rem` and `1.5rem` are still written raw **204 times** elsewhere — and each of those five has an exact token. Use the token. …

How to install
mdr add aleksandarbisevac/claude-plugins/writing-css@sha256:afe7f271941786e9The line at the top of this page pins the label git:20260911.ae46613, 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.
