# Dub

> Extracted from [https://dub.co/](https://dub.co/) 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

Dub uses a light canvas (#FFFFFF) with a palette led by #000000. Type is set in **Inter**, **Satoshi** (display), **Geist Mono** (mono), with 18px body text. Layout: 1080px container, none-detected navigation, 12 sections. Built with next.js, tailwind, radix-ui, 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` | `#FFFFFF` | 1 0 0 | bg | 81.4% | `--tw-ring-offset-color` |

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Inter** | body | 400, 500, 600 | 76.2% | webfont |
| **Satoshi** (CSS: `satoshi`) | display | 500 | 22.4% | webfont |

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

Scale (px): 8, 10, 12, 14, 16, 18, 20, 24, 30, 36, 40, 48. Effective ratio ≈ 1.178 (close to a minor third). Body 18px at line-height 1.556; display 48px with tracking 0em. Headings are sentence case. On a 390px viewport the body is 16px and display 36px.

## Layout

Spacing follows a 4px base unit; the most used steps are 4, 6, 8, 10, 12, 14, 16, 20, 24, 32, 40, 45.5, 48, 164px. Sections open with about 81px of space before their first line of text. Content sits in a 1080px container on a 2-column grid. Text density 0.077 (text area / page area).

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

1. **section** (56px, bg #FFFFFF)
2. **hero** — “Turn clicks into revenue” (2082px, bg #FFFFFF)
3. **section** — “It starts with a link” (1274px, bg #FFFFFF)
4. **section** — “Measure what matters” (1294px, bg #FFFFFF)
5. **section** — “Connect with your favorite tools” (481px, bg #FAFAFA)
6. **section** — “Grow with partnerships” (1290px, bg #FFFFFF)
7. **section** — “Built to scale” (799px, bg #FAFAFA)
8. **section** — “Enterprise-grade link infrastructure” (1322px, bg #FFFFFF)
9. **section** — “Trusted by startups and enterprises” (1699px, bg #FFFFFF)
10. **logos** — “We ship fast” (770px, bg #FFFFFF)
11. **logos** — “Supercharge your marketing efforts” (608px, bg #171717)
12. **footer** — “Compare” (530px, bg #FFFFFF)

## Elevation & Depth

Style: subtle. Most used shadows:

- `rgba(0, 0, 0, 0.05) 0px 1px 2px 0px`
- `rgba(0, 0, 0, 0.1) 0px 4px 6px -1px, rgba(0, 0, 0, 0.1) 0px 2px 4px -2px`
- `rgba(0, 0, 0, 0.2) 0px 2px 6px 0px inset`

## Shapes

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

## Components

- **button-primary**: backgroundColor `#000000`, textColor `#FFFFFF`, rounded `8px`, padding `8px 20px`, height `38px`, fontFamily `Inter`, fontSize `14px`, fontWeight `500`, border `1px solid #000000`, shadow `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.05) 0px 1px 2px 0px` (e.g. “Start for free”)
- **button-secondary**: backgroundColor `#FFFFFF`, textColor `#171717`, rounded `8px`, padding `6px 12px`, height `34px`, fontFamily `Inter`, fontSize `14px`, fontWeight `400`, border `1px solid #D4D4D4` (e.g. “Learn more”)
- **card**: rounded `8px`, padding `0px`, border `1px solid #E5E5E5`

## Do's and Don'ts

- Do reserve `#000000` for primary actions and highlights; it covers only 1.2% of the painted page.
- Do set body copy in Inter at 18px / 1.556.
- Do use Satoshi only for display sizes, not for body text.
- Don't introduce font weights beyond 400, 500, 600.
- Do keep corners at 8px 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.
