# Clerk

> Extracted from [https://clerk.com/](https://clerk.com/) 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

Clerk uses a light canvas (#F7F7F8) with a palette. Type is set in **Suisse Int'l** (display + body), **Söhne Mono** (mono), with 13px body text. Layout: 1264px container, top-sticky+transparent navigation, 6 sections. Built with next.js, tailwind, radix-ui, posthog, vercel.

## 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.

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Suisse Int'l** (CSS: `suisse`) | display, body | 400, 500, 600, 700 | 80.9% | webfont |
| **Söhne Mono** (CSS: `soehneMono`) | mono | 400 | 16.9% | webfont |

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

Scale (px): 10, 11, 12, 13, 15, 16, 17, 18, 32, 56. Effective ratio ≈ 1.276 (close to a major third). Body 13px at line-height 1.538; display 56px with tracking -0.035em. Headings are sentence case. On a 390px viewport the body is 13px and display 32px.

## Layout

Spacing follows a 4px base unit; the most used steps are 2, 4, 6, 8, 10, 12, 16, 20, 24, 32, 40px. Sections open with about 128px of space before their first line of text. Content sits in a 1264px container on a 4-column grid. Text density 0.101 (text area / page area).

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

1. **nav** (42px, bg #F7F7F8)
2. **hero** — “Create your account” (3259px, bg #FFFFFF)
3. **section** — “Multi-tenancy” (893px, bg #F7F7F8)
4. **section** — “Agents build faster and more securely with Clerk” (856px, bg #F7F7F8)
5. **section** — “Integrations” (1960px, bg #131316)
6. **footer** (413px, bg #F7F7F8)

## Elevation & Depth

Style: layered. Most used shadows:

- `rgba(19, 19, 22, 0.024) 0px 1px 1px -0.5px, rgba(19, 19, 22, 0.024) 0px 3px 3px -1.5px, rgba(19, 19, 22, 0.024) 0px 6px 6px -3px, rgba(19, 19, 22, 0.024) 0px 12px 12px -6px, rgba(19, 19, 22, 0.024) 0px 24px 24px -12px`
- `rgba(0, 0, 0, 0.1) 0px 1px 4px 0px`
- `rgba(0, 0, 0, 0.1) 0px 1px 3px 0px, rgba(0, 0, 0, 0.1) 0px 1px 2px -1px`

## Shapes

Dominant corner radius is a full pill; radii in use: 4px, 6px, 8px, 10px, 12px, 16px, pill. Borders: hairline (1px).

## Components

- **card**: rounded `2.2px`, padding `0px`, shadow `rgba(19, 19, 22, 0.024) 0px 0px 0px 1px, rgba(19, 19, 22, 0.024) 0px 1px 1px -0.5px, rgba(19, 19, 22, 0.024) 0px 3px 3px`

## Do's and Don'ts

- Do set body copy in Suisse Int'l at 13px / 1.538.
- Do tighten large headlines (-0.035em at 56px).
- Don't introduce font weights beyond 400, 500, 600, 700.
- Do keep corners at pill 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.
