# Tailscale

> Extracted from [https://tailscale.com/](https://tailscale.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

Tailscale uses a light canvas (#F9F7F6) with a palette led by #1F1E1E. Type is set in **Inter** (display + body), with 16px body text. Layout: 1312px container, top-sticky navigation, 8 sections. Built with next.js, tailwind, sanity, google-tag-manager, 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.

| Token | Hex | OKLCH | Role | Share of paint | CSS variable |
|---|---|---|---|---|---|
| `background` | `#F9F7F6` | 0.977 0.003 48.7 | bg | 43.1% | `--color-neutral-100` |
| `surface` | `#FFFFFF` | 1 0 0 | surface | 36.9% | `--color-white` |
| `on-surface` | `#2E2D2D` | 0.298 0.001 17.2 | text | 8.9% | `--color-gray-700` |
| `on-surface-variant` | `#2E2D2DCC` (on bg `#575555`) | 0.298 0.001 17.3 | muted | 4.0% | — |
| `primary` | `#1F1E1E` | 0.236 0.002 17.3 | accent | 0.84% | `--color-gray-900` |
| `outline` | `#EEEBEA` | 0.942 0.004 39.5 | border | 0.65% | `--color-gray-200` |
| `blue-500` | `#5A82DE` | 0.621 0.146 264.8 | other | 1.8% | `--color-blue-500` |
| `blue-800` | `#324994` | 0.429 0.126 267.9 | other | 1.8% | `--color-blue-800` |
| `color-9` | `#FFFFFFE6` (on bg `#FEFEFE`) | 1 0 39 | other | 0.55% | — |
| `red-500` | `#D04841` | 0.589 0.173 26.7 | other | 0.46% | `--color-red-500` |
| `black` | `#181717` | 0.206 0.002 17.3 | other | 0.32% | `--color-black` |

Sparse chromatic highlights (not accents): `#BC1142`.

Contrast: text on background 12.86:1, muted text 6.91:1, accent 15.57:1.

Gradients in use: `linear-gradient(in oklab, rgb(90, 130, 222) 0%, rgb(50, 73, 148) 100%)`; `linear-gradient(90deg, rgb(249, 247, 246) 0%, rgb(249, 247, 246) 10%, rgba(249, 247, 246, 0) 100%)`.

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

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Inter** (CSS: `inter`) | display, body | 400, 500, 600 | 98.9% | webfont |
| **Mdio** (CSS: `mdio`) | other | 500 | 1.1% | webfont |

Scale (px): 12, 14, 16, 20, 32, 48, 64. Effective ratio ≈ 1.414 (close to a augmented fourth). Body 16px at line-height 1.5; display 64px with tracking -0.01em. Headings are sentence case. On a 390px viewport the body is 15px and display 37.5px.

## Layout

Spacing follows a 4px base unit; the most used steps are 4, 8, 10, 12, 14, 20, 24, 32, 64px. Sections open with about 97px of space before their first line of text. Content sits in a 1312px container on a 12-column grid. Text density 0.133 (text area / page area).

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

1. **logos** (129px, bg #F9F7F6)
2. **hero** — “The best secure connectivity platform for the AI era” (1237px, bg #F9F7F6)
3. **logos** — “choose Tailscale 50,000 businesses” (961px, bg #F9F7F6)
4. **section** — “Easy, secure, identity-based access to anything” (1273px, bg #F9F7F6)
5. **section** — “But don’t just take our word for it. Developer approved,” (620px, bg #F9F7F6)
6. **logos** — “Cross-platform. Infrastructure agnostic. Over 100 integrations.” (608px, bg #F9F7F6)
7. **section** — “Secure your networking using identity with Tailscale” (330px, bg #2E2D2D)
8. **footer** — “Social” (539px, bg #FFFFFF)

## Elevation & Depth

Style: subtle. Most used shadows:

- `rgba(24, 23, 23, 0.02) 0px 4px 8px 0px`

## Shapes

Dominant corner radius 16px; radii in use: 8px, 16px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#1F1E1E`, textColor `#FFFFFF`, rounded `8px`, padding `8px 12px`, height `36px`, fontFamily `Inter`, fontSize `16px`, fontWeight `500` (e.g. “Get started - it’s free!”)
- **button-secondary**: textColor `#1F1E1E`, rounded `9999px`, padding `8px 12px`, height `36px`, fontFamily `Inter`, fontSize `14px`, fontWeight `500`, border `1px solid #1F1E1E1A` (e.g. “Engineering”)
- **card**: rounded `16px`, padding `32px`, backgroundColor `#FFFFFF`, border `1px solid #EEEBEA`, shadow `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0`

## Do's and Don'ts

- Do reserve `#1F1E1E` for primary actions and highlights; it covers only 0.84% of the painted page.
- Do set body copy in Inter at 16px / 1.5.
- Do tighten large headlines (-0.01em at 64px).
- Don't introduce font weights beyond 400, 500, 600.
- Do keep corners at 16px 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.
