# Rsms

> Extracted from [https://rsms.me/](https://rsms.me/) on 2026-11-12 by Emblematic. Every value below was read from the rendered DOM (computed styles, `document.fonts`, and the fonts Chrome actually used to paint text), not estimated from pixels. When the YAML front matter and this prose disagree, the YAML wins. Copy values from this file exactly; don't transcribe them from memory. Don't copy logos, imagery, illustrations or marketing copy.

## Overview

Rsms uses a light canvas (#FFFFFF) with a palette. Type is set in **Inter**, **Inter Display** (display), with 16px body text. Layout: 1088px container, none-detected navigation, 1 sections. Built with google-tag-manager, cloudflare, github-pages, fastly.

## Colors

Area-weighted from painted backgrounds, text and borders on the 1440px light capture. Roles are inferred from usage (largest background, most text, interactive fills). Every hex is an exact computed value; a role marked *unverified* is a best guess that has not passed review, so its canonical token (e.g. `primary`) is left out of the front matter.

| Token | Hex | OKLCH | Role | Share of paint | CSS variable |
|---|---|---|---|---|---|
| `background` | `#FFFFFF` | 1 0 0 | bg | 86.5% | `--background-color` |
| `on-surface` | `#000000` | 0 0 0 | text | 11.9% | `--foreground-color` |
| `box-link-hover-color` | `#00000012` (on bg `#EDEDED`) | 0 0 0 | other | 0.85% | `--box-link-hover-color` |
| `foreground-color-dimmed` | `#00000066` (on bg `#999999`) | 0 0 0 | other | 0.36% | `--foreground-color-dimmed` |
| `menu-inactive-color` | `#0000004D` (on bg `#B3B3B3`) | 0 0 0 | other | 0.32% | `--menu-inactive-color` |

Sparse chromatic highlights (not accents): `#FF4A00` (`--hot-orange`).

Declared brand/accent tokens: `--accent-color` = `#0366D6` (declared, not painted on this page).

Contrast: text on background 21:1.

The site responds to `prefers-color-scheme: dark`; the `-dark` tokens hold the dark-mode roles.

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Inter** (CSS: `Inter var`) | body | 400, 600 | 86.0% | webfont |
| **Inter Display** (CSS: `InterDisplay var`) | display | 500, 600 | 14.0% | webfont |

Declared in `@font-face` but not used to paint text on this page: IBM Plex Mono, Inter Variable. Don't treat these as the page's fonts.

Scale (px): 16, 24, 32. Effective ratio ≈ 1.414 (close to a augmented fourth). Body 16px at line-height 1.5; display 32px with tracking -0.005em. Headings are title case. On a 390px viewport the body is 16px and display 32px.

## Layout

Spacing follows a 4px base unit; the most used steps are 2, 4, 6, 16, 24, 32, 48, 64, 112, 176px. Content sits in a 1088px container on a 6-column grid. Text density 0.146 (text area / page area).

Section order (desktop). Kinds below the review threshold are shown as *section*:

1. **footer** — “Hello, I'm Rasmus” (2060px, bg #FFFFFF)

## Shapes

Dominant corner radius 2px; radii in use: 2px. Borders: none.

## Do's and Don'ts

- Do set body copy in Inter at 16px / 1.5.
- Do use Inter Display only for display sizes, not for body text.
- Do tighten large headlines (-0.005em at 32px).
- Don't introduce font weights beyond 400, 500, 600.
- Don't add drop shadows; depth comes from tone and borders.
- Do keep corners at 2px for most controls.
- Do snap spacing to multiples of 4px.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
