Notion 风格

version: alpha
name: Notion-design-analysis
description: Notion presents itself as the all-in-one workspace through a confident, illustration-rich brand voice — anchored by a deep navy hero band ({colors.brand-navy}) decorated with brand-colored sticky-note dots and mesh wire illustrations, a signature purple pill primary CTA ({colors.primary}), and a rich palette of pastel-tinted feature cards that echo the colorful database properties of the live product. The system uses a Notion-Sans (Inter-based) typeface across every UI surface, anchors a 4-tier pricing comparison (Free / Plus / Business / Enterprise), and presents the live workspace UI mockup directly inside the hero band. Coverage spans homepage, Enterprise, Product AI, Product Agents, Startups, and Pricing surfaces.

## Overview

Notion presents itself as the all-in-one workspace through a confident, illustration-rich brand voice. The homepage opens with **"Meet the night shift."** rendered centered over a deep navy hero band ({colors.brand-navy}), decorated with brand-colored sticky-note dots and mesh wire illustrations scattered around the headline. The signature **purple pill primary CTA** ({colors.primary}) "Get Notion free" sits at the visual center, paired with an outlined "Request a demo" secondary. Below the buttons, a real Notion workspace UI mockup card (the "Ramp HQ" kanban board) breaks out of the hero band with a deep diffuse drop shadow.

Below the hero, the page cycles through a distinctive sequence of feature sections: a dense sticky-note "Keep work moving 24/7" panel with red/blue/green/purple/teal status icons; a **bold yellow** ({colors.card-tint-yellow-bold}) "Ask your on-demand assistants" banner card flanked by orange/rose/mint pastel feature tiles showing assistant UI mockups; and a "Bring all your work together" 3-column grid with brand-colored mockups (sky-blue tutorial card, light Notion calendar, brown/rust testimonial slate). The pricing page renders 4 tiers (Free / Plus / Business / Enterprise) horizontally with one tier featured (purple-bordered) and a dense feature comparison table running below.

The system uses a Notion-Sans typeface (Inter-based) across every UI surface — humanist-geometric character that pairs naturally with the colorful illustrations. Buttons are `{rounded.md}` (8px) rectangles, NOT pills — distinguishing Notion's sober rectangular geometry from competitors that use pills universally. Cards use `{rounded.lg}` (12px) consistently.

**Key Characteristics:**
- Deep navy hero band ({colors.brand-navy}) with scattered sticky-note dots + mesh wire decorative illustrations
- **Signature purple pill** ({colors.primary}) primary CTA — Notion's recognizable "Get Notion free" button color
- Real Notion workspace UI mockup card embedded in the hero with deep drop shadow
- Bold yellow feature banner ({colors.card-tint-yellow-bold}) for high-emphasis content sections
- Pastel feature card palette (peach, rose, mint, lavender, sky, yellow) echoing the live product database properties
- Notion-Sans (Inter-based) across every UI surface
- 8px-rounded buttons (NOT pills), 12px-rounded cards — sober editorial geometry
- 4-tier pricing comparison with dense feature table
- Centered hero layout (different from the left-aligned norm of most B2B SaaS)

### Hierarchy

| Token | Size | Weight | Line Height | Letter Spacing | Use |
|---|---|---|---|---|---|
| `{typography.hero-display}` | 80px | 600 | 1.05 | -2px | Hero ("Meet the night shift") |
| `{typography.display-lg}` | 56px | 600 | 1.10 | -1px | Section openers |
| `{typography.heading-1}` | 48px | 600 | 1.15 | -0.5px | Page-level headlines ("Try for free") |
| `{typography.heading-2}` | 36px | 600 | 1.20 | -0.5px | Subsection headlines ("Keep work moving 24/7") |
| `{typography.heading-3}` | 28px | 600 | 1.25 | 0 | Card titles |
| `{typography.heading-4}` | 22px | 600 | 1.30 | 0 | Feature tile titles |
| `{typography.heading-5}` | 18px | 600 | 1.40 | 0 | FAQ questions |
| `{typography.subtitle}` | 18px | 400 | 1.50 | 0 | Hero subtitle |
| `{typography.body-md}` | 16px | 400 | 1.55 | 0 | Primary body text |
| `{typography.body-md-medium}` | 16px | 500 | 1.55 | 0 | Body emphasis |
| `{typography.body-sm}` | 14px | 400 | 1.50 | 0 | Secondary body |
| `{typography.body-sm-medium}` | 14px | 500 | 1.50 | 0 | Active sidebar, button labels |
| `{typography.caption-bold}` | 13px | 600 | 1.40 | 0 | Badge labels |
| `{typography.button-md}` | 14px | 500 | 1.30 | 0 | Button labels |

### Principles
- Tight hero leading (1.05) on 80px display
- Negative letter-spacing on display sizes (-2px to -0.5px)
- Generous body leading (1.55) for documentation readability
- 600 weight for headlines + 500 for buttons; 400 body

## Layout

### Spacing System
- **Base unit**: 4px (8px primary increment)
- **Tokens**: `{spacing.xxs}` (4px) through `{spacing.hero}` (120px)
- **Section rhythm**: Marketing pages use `{spacing.section-lg}` (96px); pricing tightens to `{spacing.section}` (64px)

### Grid & Container
- 1280px max-width with 32px gutters
- Pricing: 4-tier card row at desktop with dense comparison table
- Homepage: centered hero with workspace mockup below buttons; alternating colorful feature card sections

### Whitespace Philosophy
Marketing surfaces use generous breathing room between feature card bands. Workspace mockup card on hero gets full-width treatment with deep drop shadow.

## Elevation & Depth

| Level | Treatment | Use |
|---|---|---|
| 0 (flat) | No shadow; `{colors.hairline}` border | Default cards, table rows |
| 1 (subtle) | `rgba(15, 15, 15, 0.04) 0px 1px 2px 0px` | Hover-elevated tiles |
| 2 (card) | `rgba(15, 15, 15, 0.08) 0px 4px 12px 0px` | Feature cards |
| 3 (mockup) | `rgba(15, 15, 15, 0.20) 0px 24px 48px -8px` | Hero workspace mockup card |
| 4 (modal) | `rgba(15, 15, 15, 0.16) 0px 16px 48px -8px` | Modals, dropdowns |

### Decorative Depth
- Hero workspace mockup card uses deep diffuse drop shadow (Level 3) — significant elevation against the navy band
- Pastel feature cards carry their own visual weight via tint backgrounds
- Sticky-note dot illustrations and mesh wires add atmospheric decoration to navy hero

## Do's and Don'ts

### Do
- Use `{colors.primary}` (purple) as the dominant CTA across all surfaces — it's the brand's recognizable signal
- Pair deep navy hero bands ({colors.brand-navy}) with the purple button + decorative sticky-note dots
- Use pastel feature card tints (peach, rose, mint, lavender, sky, yellow) generously
- Use `{colors.card-tint-yellow-bold}` for high-emphasis "Ask the assistant"-style banner cards
- Apply `{rounded.md}` (8px) to buttons consistently — Notion uses rectangles, not pills
- Apply `{rounded.lg}` (12px) to all card families
- Maintain Notion-Sans across every UI surface
- Use the workspace mockup card on hero bands to show actual product UI

### Don't
- Don't use the purple for body text or large background surfaces
- Don't use pill-shaped buttons; Notion's geometry is rectangular-sober
- Don't mix link-blue ({colors.link-blue}) with primary-purple ({colors.primary}) — they have distinct roles
- Don't apply heavy shadows on flat documentation cards
- Don't replace Notion-Sans with a generic Inter

## Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|---|---|---|
| Mobile (small) | < 480px | Single column. Hero 36px. Pricing 1-up. |
| Mobile (large) | 480 – 767px | Feature cards 2-up. Hero 48px. |
| Tablet | 768 – 1023px | 2-column feature grids. Hero 56px. |
| Desktop | 1024 – 1279px | 4-tier pricing card row. Hero 72px. |
| Wide Desktop | ≥ 1280px | Full 80px hero presentation. |

### Touch Targets
- Buttons render at 40–44px effective height
- Form inputs render at 44px height
- Pill tabs ~32px → 44px on mobile

### Collapsing Strategy
- **Promo banner** stays full-width; truncates at < 480px
- **Top nav** below 1024px collapses to hamburger
- **Hero band**: workspace mockup card moves below text/buttons on mobile
- **Pricing tiers**: 4-column → 2-column tablet → 1-column mobile
- **Feature cards**: 3-up desktop → 2-up tablet → 1-up mobile
- **Hero typography**: 80px → 56px → 48px → 36px
- **Footer**: 6-column desktop → 3-column tablet → accordion mobile

### Image Behavior
- Workspace mockup card maintains aspect ratio
- Pastel illustrations inside feature cards scale proportionally
- Customer logo wall: wordmarks at consistent 60–80px height

## Iteration Guide

1. Focus on ONE component at a time
2. Reference component names and tokens directly
3. Run `npx @google/design.md lint DESIGN.md` after edits
4. Add new variants as separate `components:` entries
5. Default to `{typography.body-md}` for body
6. Keep `{colors.primary}` (purple) as the primary CTA — distinct from `{colors.link-blue}` for inline links
7. Use `{rounded.md}` for buttons (rectangles), `{rounded.lg}` for cards, `{rounded.full}` for pill tabs/badges only

## Known Gaps

- Specific dark-mode token values not surfaced beyond hero bands
- Animation/transition timings not extracted; recommend 150–200ms ease
- Form validation success state not explicitly captured
- Pastel-tint mapping (which feature uses which tint) is observation-based — the actual brand library may have more entries
