# Obsidian

> Extracted from [https://obsidian.md/](https://obsidian.md/) 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

Obsidian uses a dark canvas (#0F0F0F) with a palette led by #7C3AED. Type is set in **SF Pro (system-ui)** (display + body), with 18px body text. Layout: 1120px container, top-fixed+transparent navigation, 8 sections. Built with tailwind, 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` | `#0F0F0F` | 0.168 0 0 | bg | 63.7% | `--color-primary` |

Contrast: text on background 16.52:1, muted text 10.09:1, accent 3.36:1.

Gradients in use: `linear-gradient(to top, rgb(15, 15, 15), rgba(15, 15, 15, 0))`.

The site does not change under `prefers-color-scheme: dark`.

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **SF Pro (system-ui)** (CSS: `ui-sans-serif`) | display, body | 400, 500, 600, 700 | 99.9% | system (stack `ui-sans-serif, system-ui, -apple-system, "system-ui", Roboto`, resolved on macos) |

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

Scale (px): 6, 9, 10, 11, 12, 13, 14, 16, 18, 20, 24, 36, 60. Effective ratio ≈ 1.351 (close to a perfect fourth). Body 18px at line-height 1.333; display 60px with tracking -0.02em. Headings are sentence case. On a 390px viewport the body is 18px and display 50.7px.

## Layout

Spacing follows a 4px base unit; the most used steps are 2, 3, 4, 6, 8, 12, 16, 23, 24, 32, 48, 96, 160px. Sections open with about 96px of space before their first line of text. Content sits in a 1120px container on a 2-column grid. Text density 0.111 (text area / page area).

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

1. **nav** (90px, bg #0F0F0F)
2. **nav** (90px, bg #0F0F0F)
3. **hero** — “Sharpen your thinking.” (1724px, bg #0F0F0F)
4. **section** — “Spark ideas.” (1446px, bg #0F0F0F)
5. **section** — “Sync securely.” (832px, bg #0F0F0F)
6. **section** — “Publish instantly.” (1179px, bg #0F0F0F)
7. **section** — “It’s your time to shine.” (793px, bg #0F0F0F)
8. **footer** (620px, bg #0F0F0F)

## Elevation & Depth

Style: elevated. Most used shadows:

- `rgba(0, 0, 0, 0.1) 0px 20px 25px -5px, rgba(0, 0, 0, 0.1) 0px 8px 10px -6px`
- `rgba(0, 0, 0, 0.25) 0px 25px 50px -12px`
- `rgba(0, 0, 0, 0.1) 0px 1px 3px 0px, rgba(0, 0, 0, 0.1) 0px 1px 2px -1px`

## Shapes

Dominant corner radius 12px; radii in use: 2px, 4px, 6px, 8px, 12px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#7C3AED`, textColor `#FFFFFF`, rounded `8px`, padding `16px 24px`, height `60px`, fontFamily `SF Pro (system-ui)`, fontSize `20px`, fontWeight `500`, shadow `rgb(255, 255, 255) 0px 0px 0px 0px inset, rgba(255, 255, 255, 0.1) 0px 0px 0px 1px inset, rgba(0, 0, 0, 0.1) 0px 1px 3px` (e.g. “Get Obsidian for”)
- **card**: rounded `12px`, padding `0px`, backgroundColor `#1F1F1F`, shadow `rgb(255, 255, 255) 0px 0px 0px 0px inset, rgba(255, 255, 255, 0.05) 0px 0px 0px 1px inset, rgba(0, 0, 0, 0) 0px 0px 0px `

## Do's and Don'ts

- Do reserve `#7C3AED` for primary actions and highlights; it covers only 0.27% of the painted page.
- Do set body copy in SF Pro (system-ui) at 18px / 1.333.
- Do tighten large headlines (-0.02em at 60px).
- Don't introduce font weights beyond 400, 500, 600, 700.
- Do keep corners at 12px for most controls, and use the larger radii only for cards and media.
- 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.
