# beehiiv Design System

## Overview

beehiiv describes itself as: “beehiiv is the newsletter platform built for creators, publishers, and businesses. Grow, publish, and monetize your audience in one place.” The interface is dark, built on **Deep Indigo (#060419)** with **White (#FFFFFF)** text, and **Indigo (#2F39BA)** as the main accent.

Type is set in **ClashGroteskFont** and **SatoshiFont**. Headlines run large; body text is 18px. Depth comes from hairline borders and inset highlights rather than drop shadows. Corners are mostly 6px.

Measured from [beehiiv.com](https://www.beehiiv.com/) on November 4, 2026 at 1440×900 and 390×844 from 435 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 12 roles, plus gradient stops #FFDCFF, #FF5EC4.

- **Deep Indigo (#060419):** Page background, seen 12 times. Token `background`, CSS `--surface-page`.

- **White 20% (#FFFFFF33):** Secondary dividers, seen 3 times. Token `outline-variant`, CSS `--border-strong`.

## Typography

**ClashGroteskFont** and **SatoshiFont** share the interface. Fallback stack: `ClashGroteskFont, ClashGroteskFont Fallback, sans-serif`.

- **display-hero:** ClashGroteskFont 64px at weight 700, line height 1.06. Oversized hero statements.
- **headline-display:** ClashGroteskFont 60px at weight 700, line height 1, uppercase (42px on mobile). Page title (h1).
- **headline-lg:** ClashGroteskFont 48px at weight 700, line height 1, uppercase (36px on mobile). Section headings (h2).
- **headline-md:** SatoshiFont 30px at weight 500, line height 1.2. Sub-section headings.
- **headline-sm:** SatoshiFont 24px at weight 700, line height 1.33. Card and feature titles.
- **title-lg:** SatoshiFont 20px at weight 700, line height 1.4. Small titles.

- **label-sm:** SatoshiFont 12px at weight 500, line height 1.33. Small labels and badges.

## Layout

Spacing is mostly on a 4px grid (86% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** xs 4px, sm 8px, md 12px, lg 24px, xl 64px.
- **Gaps:** 8px is the most common gap in flex and grid layouts.
- **Breakpoints:** 600px, 639px, 640px, 650px, 768px, 1024px, 1280px, 1283px, 1284px, 1536px.

## Elevation & Depth

The design avoids drop shadows. Layers are separated by tonal surface steps (#0D0B28) and hairline rings:

- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgb(255, 94, 196) 0px 0px 0px 2px inset, rgb(6, 4, 25) 0px 0px 0px 4px inset`

## Shapes

Most elements use 6px corners. Measured radii, most used first:

- **sm (6px):** 168 elements.
- **lg (12px):** 120 elements.
- **md (8px):** 40 elements.
- **full (9999px):** 16 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“Sign up with Google”):** #2F39BA fill, #FFFFFF text, 16px/400, 6px radius, padding 0px.
- **button-outline (“Sign up with email”):** #131125 fill, #FFFFFF text, 16px/400, 6px radius, padding 0px.
- **button-secondary (“Sign up for free”):** #FFFFFF fill, #060419 text, 14px/600, 6px radius, padding 8px 12px, border 1px solid #FFFFFF.
- **button-ghost (“Product”):** transparent fill, #000000 text, 16px/400, padding 0px.
- **input-field (“Subscribers”):** transparent fill, #000000 text, 16px/400, padding 0px.
- **card:** #0D0B28 fill, #000000 text, 16px/400, 12px radius, padding 0px, border 1px solid #FFFFFF0F.
- **link:** transparent fill, #FFFFFF text, padding 0px.

## Do's and Don'ts

- Do use #060419 for the page and lift surfaces in small steps: #0D0B28.
- Do keep text in 4 levels: #FFFFFF, #F7F5FF, #DDDCE8, #9393A9.
- Do reserve #2F39BA for primary actions and key highlights.
- Do reuse the measured spacing steps (8px, 12px, 24px).
- Do use 6px corners on most elements; larger surfaces also use 12px and 8px.
- Don't add drop shadows for depth; use hairline rings and tonal surfaces.
- Don't introduce new font families beyond ClashGroteskFont and SatoshiFont.
- Don't use #2F39BA for large backgrounds or body text.
- Don't make interface transitions slower than 0.35s.

## Motion

Interface transitions are quick: 0.15s, 0.3s, 0.35s, 0.125s.

- **Easing:** `cubic-bezier(0.4, 0, 0.2, 1)`, `cubic-bezier(0, 0, 0.2, 1)`, `cubic-bezier(0.65, 0, 0.35, 1)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
