rem, px or relative units for each kind of value. Use when defining spacing and sizing tokens, control heights or media queries, or when a layout breaks under enlarged text.
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
# Sizing Units ## The Question the Unit Answers A unit is not a formatting preference. It is a declaration of what happens to a value when the user enlarges text. - `rem` — this value belongs to the text and must grow with it. - `px` — this value belongs to the screen and must stay put. - `%`, `fr`, `ch`, `clamp()`, `min()` — this value belongs to the available space. Pick the unit by answering that question, not by picking a house style and applying it everywhere. Both absolutist positions — all-rem and all-px — produce defects, and they are different defects. ## Zoom Is Not the Font-Size Setting The common argument for px everywhere is that browsers already have full-page zoom, so the root font size can be ignored. They are separate controls serving separate people. - **Full-page zoom** magnifies everything, layout included. It buys larger text at the cost of horizontal scrolling and fewer items per screen. - **The browser's default font size** enlarges text and leaves the layout alone. This is what a user with low vision sets once, years ago, and never touches again. They will not switch to zoom because your product ignored it. …

How to install
mdr add dembrandt/dembrandt-skills/sizing-units@sha256:3584d95422db86f3The line at the top of this page pins the label git:20261008.20de5f2, 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.
