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
# Support dark mode with prefers-color-scheme More than half of users prefer dark mode for reduced eye strain, especially in low-light environments. Users with photosensitivity rely on it. Implementing dark mode via prefers-color-scheme respects the user's OS preference without them needing to find a toggle, and CSS custom properties make it a clean, maintainable addition rather than a disruptive refactor. ## Quick Reference - Use @media (prefers-color-scheme: dark) to apply dark mode styles - Define light/dark colors as CSS custom properties on :root for easy switching - Support a manual toggle by storing preference in localStorage and setting a data-theme attribute - Ensure dark mode colors maintain WCAG contrast ratios ## Check Check if this CSS supports dark mode. Look for prefers-color-scheme usage or a data-theme attribute pattern. Identify any hard-coded colors that would look wrong in dark mode. ## Fix Implement dark mode by extracting colors to CSS custom properties and redefining them inside a prefers-color-scheme: dark media query. ## Explain …

How to install
mdr add thedaviddias/front-end-checklist/dark-mode-css@sha256:9801c7262980f295The 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.
