# AFFiNE Design System

## Overview

AFFiNE describes itself as: “AFFiNE combines docs, whiteboards, databases, and optional AI in one local-first workspace. MIT-licensed editor; self-host free for up to 10 seats per workspace.” The interface is light, built on **Snow (#F8F8F7)** with **Cool Graphite (#424149)** text, and **Vivid Blue (#1E96EB)** as the main accent.

Type is set in **Inter**. Headlines run large with tight negative tracking; body text is 16px. Depth comes from soft drop shadows. Corners are mostly 16px.

Measured from [affine.pro](https://affine.pro/) on November 5, 2026 at 1440×900 and 390×844 from 414 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 12 roles, plus gradient stops #1E96EB.

- **Snow (#F8F8F7):** Page background, seen 1 time. Token `background`.
- **Cool Graphite (#424149):** Primary text and headings, seen 32 times. Token `on-surface`, CSS `--el-text-color-regular`.
- **Near Black (#000000):** Headings and emphasis, seen 22 times. Token `on-surface-strong`, CSS `--cc-btn-primary-hover-border-color`.
- **Slate (#505050):** Secondary text, seen 4 times. Token `on-surface-variant`.
- **Slate (#5E5E5E):** Muted text and metadata, seen 5 times. Token `on-surface-muted`.
- **White (#FFFFFF):** Raised areas one step from the page, seen 30 times. Token `surface-container-low`, CSS `--el-bg-color`.
- **White 14% (#FFFFFF24):** Translucent fill for cards and controls, seen 5 times. Token `overlay`.
- **White 86% (#FFFFFFDB):** Stronger translucent fill, seen 3 times. Token `overlay-strong`.
- **Near Black 10% (#0000001A):** Borders and dividers, seen 24 times. Token `outline`.
- **White 40% (#FFFFFF66):** Secondary dividers, seen 5 times. Token `outline-variant`.
- **Vivid Blue (#1E96EB):** Primary buttons and calls to action, seen 26 times. Token `primary`, CSS `--brand`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.

## Typography

**Inter** carries the whole interface. Fallback stack: `Inter, Inter Fallback, Roboto, Helvetica`.

- **headline-display:** Inter 90px at weight 500, line height 1, tracking -0.07em (40px on mobile). Page title (h1).
- **headline-lg:** Inter 60px at weight 500, line height 1.08, tracking -0.05em. Section headings (h2).
- **headline-md:** Inter 48px at weight 500, line height 1.18, tracking -0.04em (18px on mobile). Sub-section headings.
- **headline-sm:** Inter 36px at weight 500, line height 1.19, tracking -0.04em. Card and feature titles.
- **title-lg:** Inter 32px at weight 500, line height 1.25, tracking -0.04em. Small titles.
- **body-md:** Inter 16px at weight 400, line height 1.5. Body text.
- **body-lg:** Inter 18px at weight 600, line height 1.35, tracking -0.01em. Lead paragraphs.
- **body-sm:** Inter 14px at weight 400, line height 1.35. Secondary and small text.
- **caption:** Inter 13px at weight 400. Captions and fine print.
- **label-lg:** Inter 16px at weight 500, line height 1, tracking -0.02em. Large buttons and tabs.
- **label-md:** Inter 14px at weight 500, line height 1.43, tracking -0.02em. Buttons, navigation and labels.
- **label-sm:** Inter 13px at weight 600, line height 1.2. Small labels and badges.

## Layout

Spacing is mostly on a 4px grid (85% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** xs 4px, sm 8px, md 16px, lg 24px, xl 36px.
- **Sections:** 96px vertical padding between major sections.
- **Gaps:** 8px is the most common gap in flex and grid layouts.
- **Page margin:** 32px on each side of full-width sections.
- **Breakpoints:** 0px, 390px, 480px, 520px, 560px, 569px, 599px, 744px, 768px, 900px, 1000px, 1023px, 1024px, 1025px, 1180px, 1440px.

## Elevation & Depth

Raised elements use soft drop shadows. The most used recipes:

- `rgba(0, 0, 0, 0.15) 0px 1px 4px 0px`
- `rgba(0, 0, 0, 0.06) 0px 2px 4px 0px`

## Shapes

Most elements use 16px corners. Measured radii, most used first:

- **lg (16px):** 92 elements.
- **sm (10px):** 72 elements.
- **xs (4px):** 36 elements.
- **xl (34px):** 36 elements.
- **full (9999px):** 24 elements.
- **md (12px):** 16 elements.

## Components

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

- **button-primary (“Get Started”):** #1E96EB fill, #FFFFFF text, 16px/400, 34px radius, padding 0px.
- **button-primary-hover:** background #1E96EBCC, text #FFFFFF on hover.
- **button-outline (“Book a Demo”):** transparent fill, #1E96EB text, 16px/500, 34px radius, padding 10px 20px, border 1px solid #1E96EB.
- **button-outline-hover:** background #1E96EB, text #FFFFFF on hover.
- **button-ghost (“Product”):** transparent fill, #000000 text, 14px/500, 4px radius, padding 8px 12px.
- **input-field (“name@example.com”):** transparent fill, #FFFFFF text, 15px/400, padding 0px.
- **card:** #FFFFFF fill, #424149 text, 24px/400, 16px radius, padding 0px 24px 24px 24px, shadow `rgba(0, 0, 0, 0.15) 0px 1px 4px 0px`.
- **link:** transparent fill, #FFFFFF text, padding 0px.

## Do's and Don'ts

- Do use #F8F8F7 for the page and lift surfaces in small steps: #FFFFFF.
- Do keep text in 4 levels: #424149, #000000, #505050, #5E5E5E.
- Do reserve #1E96EB for primary actions and key highlights.
- Do set headlines in Inter with tight tracking (-0.07em).
- Do reuse the measured spacing steps (8px, 16px, 24px).
- Do use 16px corners on most elements; larger surfaces also use 10px, 4px and 34px.
- Don't introduce new font families beyond Inter.
- Don't use #1E96EB for large backgrounds or body text.
- Don't make interface transitions slower than 0.32s.

## Motion

Interface transitions are quick: 0.2s, 0.268s, 0.218s, 0.32s.

- **Easing:** `cubic-bezier(0.16, 1, 0.3, 1)`, `ease`, `cubic-bezier(0.22, 0.61, 0.36, 1)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
