narrative: |
linear.app is built on a near-black canvas (rgb(8, 9, 10)).
The system uses #5e6ad2 as the accent for primary actions and brand signals.
Fully-rounded CTAs (9999px) signal a friendly, tactile interaction model alongside Inter Variable as the primary typeface.

# Design System — linear.app
> Extracted automatically by Clone Architect from https://linear.app
> Date: 2026-05-30
> Viewport: Desktop 1440x900 + Mobile 390x844
> Every value in this file comes from real getComputedStyle() — no approximation.
> **🤖 TL;DR for AI agents** (read this first — saves you scanning the full doc):
>
> - **Canvas**: `rgb(8, 9, 10)` is the page background. Every component composits against this.
> - **Accent**: `#5e6ad2` for primary CTAs ONLY. Never decorative.
> - **Body type**: 16px (token: `typography.body`). Default for ALL text not in a heading role.
> - **Section rhythm**: 72px between major bands. Card padding: 24px.
> - **Default radius**: 8px on buttons/inputs. Pills (`9999px`) only for icon-buttons or status chips.
>
> **Before generating UI**: import this DESIGN.md, scan §2 (Color Palette) + §4 (Components) + §10 (Agent Guide). Skip §11–12 unless extending.
## 1. Visual Theme & Atmosphere
linear.app commits fully to dark-mode as the native medium, not as a toggled alternative. The canvas is an inky black surface (`#08090a`) where elevation is communicated through subtle white-opacity gradations rather than traditional shadows — semi-transparent white borders act as the primary depth indicator, like wireframes etched in moonlight.
Typography is anchored in **Inter Variable**, deployed with OpenType features enabled globally (`"cv01", "ss03"`). These aren't decorative — they're load-bearing: without them, the typeface reverts to its generic state and the design loses its specific texture. The weight scale rejects the standard 100/200/.../900 ladder in favor of custom values (max **680** in this system) — a deliberate signal that this design system is precisely tuned, not assembled from defaults. Negative letter-spacing at display sizes (-1.408px at 64px) compresses headlines into engineered blocks, dense and authoritative.
Body text reads in Off-Cream (`#f7f8f8`) (contrast ratio 28.1:1, well above WCAG AA). **Indigo** (`#5e6ad2`) provides interactive distinction without visual aggression. Elevation is built from multi-layer shadow stacks — each level combines several blurred layers at varying offsets to simulate the way light actually falls on stacked surfaces, not the simulated drop-shadow of cheap interfaces.
Border radius varies from pill-shaped (fully rounded) to moderately rounded elements, creating visual rhythm. Motion design uses smooth easing curves for polished state transitions.
**Key Characteristics:**
- Background: Jet Black (`#08090a`)
- Primary typeface: Inter Variable
- Primary text: Off-Cream (`#f7f8f8`)
- Accent: Indigo (`#5e6ad2`)
- Display: 64px weight 510, letter-spacing -1.408px
- Shadow system: 13 distinct elevation levels
- Custom fonts loaded: Inter Variable, Berkeley Mono

### Font Weight Scale
CSS custom properties define 6 explicit weight steps:
- `--font-weight-light`: `300` — Light
- `--font-weight-normal`: `400` — Regular
- `--dp-font-weight-medium`: `500` — Medium
- `--font-weight-medium`: `510` — Medium (custom, ~500)
- `--font-weight-semibold`: `590` — SemiBold (custom, ~600)
- `--font-weight-bold`: `680` — Bold (custom, ~700)
### Full Font Size Scale
Sizes detected in the design (descending): `64px`, `48px`, `32px`, `24px`, `20px`, `18px`, `17px`, `16px`, `15px`, `14px`, `13.33px`, `13px`, `12.25px`, `12px`, `11px`, `10px`
> 9 size(s) detected outside the sampled hierarchy (48px, 32px, 24px, 18px, 17px, 15px, 12.25px, 11px, 10px). These appear on elements not in the sampled set — likely additional display sizes, marketing-section overrides, or third-party-widget styles.
### OpenType & Variable Font Features
The typography uses these OpenType features intentionally — this is a sophisticated type system, not a default fallback:
- **stylistic sets** (`ss0X`) — alternate letterforms enabled (often for brand-specific glyph variants)
**Clone instruction:** Enable these in your CSS:
```css
body {
font-feature-settings: "cv01", "ss03", "ss01";
}
```

## 4b. Component Behaviors (State Matrix)
### Interaction State Narrative
- **Button**:
- **focus:** bg transparent → rgba(255, 255, 255, 0.075), text #8a8f98 → #f3f4f5, border changes
- **FooterLink**:
- **hover:** text #f7f8f8 → #dfe1e3, border changes
*State transitions extracted via Playwright simulation — exact values in the YAML matrix below.*
```yaml
component-behaviors:

## 5. Layout Principles
### Layout Type
**top-nav + content**
### Grid
Flexbox column
### Max Width
100%
### Spacing System
Compact spacing — information density prioritized
| Token | Value |
|-------|-------|
| xxs | 2px |
| xs | 6px |
| sm | 12px |
| md | 14px |
| base | 16px |
| lg | 24px |
| xl | 32px |
| 2xl | 72px |
| 3xl | 64px |
### Border Radius Scale
| Name | Value | Use |
|------|-------|-----|
| None | 0px | No rounding |
| Xs | 4px | Tiny corners (badges, micro elements) |
| Sm | 8px | Buttons, inputs, small elements |
| Md | 12px | Cards, containers |
| Lg | 20px | Large rounded elements, pill segments |
| Xl | 32px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |
### Shape Language
| Component | Border Radius |
|-----------|---------------|
| Buttons | `9999px` |
| Cards & Containers | `8px` |
| Inputs & Forms | `6px` |
| Navigation | `none` |
| Code Blocks | `4px` |
| Page Body | `0px` |
| Primary Input | `6px` |
**Shape Personality**: Sharp + Pill Contrast — Angular precision with pill-shaped accents (status badges, tags). Creates strong visual hierarchy.
**Full Radius Spectrum**: 0px, 1px, 2px, 4px, 6px, 7px, 8px, 12px (from `allBorderRadii` scan)
## 5b. Spacing Rhythm Names
*Named spacing tokens with explicit use cases. Use these names in YOUR code instead of raw pixels for consistency.*
| Name | Value | Use case |
|------|-------|----------|
| **hero** | `64px` | Top/bottom of full-bleed hero sections |
| **section** | `32px` | Between major bands (color change, content shift) |
| **subsection** | `24px` | Within a section, between content groups |
| **card** | `14px` | Card padding, list-item spacing |
| **compact** | `12px` | Form fields, tight clusters, badge padding |
| **micro** | `6px` | Icon-text gap, tag inner padding |
**Agent rule**: NEVER hardcode raw pixel values for spacing in generated UI. Always reference these named tokens (`spacing-rhythm.section`, etc.).
## 5c. Widget & Structure Library
Structural patterns extracted from the page DOM — these are the **blueprints** an agent should follow to reproduce the page architecture (not just CSS values).
**5/8 structural patterns detected.**
### Hero Pattern
- **Composition:** centered — Centered composition — heading + subheading + CTAs stacked vertically, content centered horizontally. Common for SaaS marketing pages.
- **Viewport coverage:** full-viewport hero (≥70% screen height)

- **Subheading:** "Purpose-built for planning and building products. Designed for the AI era."
- **Media:** present, positioned top
- **CTAs:** 8 (primary: "Faster app launch")
- **Clone instruction:** Reproduce the **centered** layout. Use the heading font-size token at the documented size. Place media top of text.
### Navigation Pattern
- **Position:** static (scrolls with page)
- **Layout:** logo-left-links-right — Logo at far left, primary navigation links right-aligned
- **Height:** 72px
- **Logo:** ✓ present

- **Card dimensions:** 1432×764px (aspect 1.87:1)
- **Gap:** 0px between cards
- **Content:** ✓ image
- **Image position:** top
- **Clone instruction:** Build a 1-column grid (desktop) with cards at ~1.87:1 aspect ratio. Each card has an image at the top.
### Testimonial Pattern
- **Count:** 9 testimonial blocks
- **Layout:** grid
- **Avg quote length:** 154 chars (medium quote)
- **Includes:** ✗ no avatars | ✗ no logos | ✗ no ratings

- **Links:** 37 total
- **Height:** 464px
- **Includes:** ✗ no newsletter | ✓ social icons |
- **Clone instruction:** Build a 5-column footer with ~7 links per column, social media links.
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Layered (Level 1) | <br>`rgba(0, 0, 0, 0) 0px 8px 2px 0px`,<br>`rgba(0, 0, 0, 0.01) 0px 5px 2px 0px`,<br>`rgba(0, 0, 0, 0.04) 0px 3px 2px 0px`,<br>`rgba(0, 0, 0, 0.07) 0px 1px 1px 0px`,<br>`rgba(0, 0, 0, 0.08) 0px 0px 1px 0px` | Cards, elevated surfaces |
| Layered (Level 2) | <br>`rgba(94, 106, 210, 0.008) 0px 0px 0px 9.05908px` | Cards, elevated surfaces |
| Layered (Level 3) | <br>`rgba(0, 0, 0, 0.1) 0px 0px 0px 2px` | Cards, elevated surfaces |
| Layered (Level 4) | <br>`rgba(0, 0, 0, 0.2) 0px 0px 0px 1px` | Cards, elevated surfaces |
**Shadow Philosophy**: Multi-layered shadow system creating natural, atmospheric depth. Each shadow level combines multiple layers for realistic elevation.

## 8. Do's and Don'ts
### Do
- Use dark background (`#08090a`) as the foundation — this is a dark-mode-native design
- Use Inter Variable as the primary typeface — it defines the brand personality
- Use weight 680 for the heaviest text — this design uses a custom heavy weight, not the standard 700 (bold)
- Use negative letter-spacing (-1.408px) at display sizes for compressed, editorial headlines
- Use the extracted shadow patterns for elevation — they are tuned to match the brand palette
- Use full-pill radius (9999px) only for specific elements (avatars, pills, toggles)
- Use Indigo (`#5e6ad2`) as the primary accent — it's the brand's signature interactive color
- Use pill-shaped radius (9999px) for primary CTA buttons — the brand uses fully-rounded, pill CTAs
- Use 8px border-radius on cards — consistent with the grid card corners
- Style form inputs with a `1px solid rgba(255, 255, 255, 0.08)` border — use border-based inputs, not floating labels or underline-only
- Maintain nav height at 72px — consistent vertical space for the navigation bar
- Make the hero full-viewport (≥70% screen height) — this design uses an immersive hero, not a tall navbar
- Include exactly 8 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose
- Each card includes a top image — imagery is part of the card identity, not optional
- Lay out testimonials in a grid (9+ items) — quantity signals scale and trust
- Build a content-dense footer (5 columns, ~37 links) — this site treats the footer as a sitemap, not an afterthought
### Don't
- Don't use light backgrounds — the dark canvas is the native medium
- Don't substitute with generic sans-serif or serif — the custom font carries the brand
- Don't substitute weight 680 with the standard 700 — the custom value is part of the brand's type personality
- Don't increase letter-spacing on headings — the type is designed to run tight at scale
- Don't invent new shadow values — use only the extracted shadow levels
- Don't apply pill radius on rectangular buttons or cards — it's reserved for specific interactive elements
- Don't introduce additional saturated accent colors — the palette is intentionally controlled
- Don't use rectangular buttons for primary actions — the rounded pill shape is the brand standard
- Don't remove the input border — the border is the primary affordance indicator for form fields
- Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence
- Don't make the nav sticky — this design lets it scroll away to maximize content focus
## 7b. Enforceable Brand Rules
*Structured Do/Don't with reasoning and validation tests. Agents can programmatically verify generated UI.*
```yaml
rules:
- id: brand-canvas-001
type: do
rule: "Always use the page background `rgb(8, 9, 10)` as the base canvas"
why: "Every component is designed to composit against this exact tone"
test: "document.body.style.backgroundColor === 'rgb(8, 9, 10)'"
- id: brand-accent-001
type: do
rule: "Reserve `#5e6ad2` for primary CTAs and brand-mark signals only"
why: "Single chromatic assertion device — overuse dilutes meaning"
test: "querySelectorAll('[style*=\"#5e6ad2\"]').length <= 3 per fold"
```
## 9. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Large | 600px | Expanded mobile layout |
| Mobile Large | 640px | Expanded mobile layout |
| Tablet | 768px | Multi-column grids begin |
| Tablet | 1024px | Multi-column grids begin |
| Desktop | 1280px | Full feature layout |
### Token Diff — Desktop vs Mobile
| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `64px` | `38px` |
| heading | line-height | `64px` | `41.8px` |
| heading | letter-spacing | `-1.408px` | `-0.836px` |
| nav | flex-direction | `row` | `column` |
| button | width | `73px` | `auto` |
### Collapsing Strategy
- Headlines: 64px → 38px on mobile
- Navigation: horizontal links → hamburger menu on mobile
- Cards: multi-column → stacked vertical on mobile
- Footer: multi-column → stacked single column on mobile
### Touch Targets
- Buttons: 0px 12px padding
- Navigation: adequate spacing between items
- Interactive elements: minimum 44px touch target recommended
### Collapsing Narrative
How the structural patterns adapt from desktop to mobile (extracted from both viewport extractions):
- **Hero CTAs:** 8 on desktop → 3 on mobile (secondary CTAs dropped on small screens).
- **Navigation collapses to hamburger** — 5 links visible on desktop, 1 on mobile (the rest hide behind a menu toggle).
- **Footer columns collapse:** 5 columns (desktop) → 2 columns (mobile).
## 9b. Visual Tone & Photography
**Tone:** Illustration-driven
The site relies primarily on illustrations, vector art, and decorative SVG elements rather than photography. Use commissioned illustrations, icon sets, or generated graphics for clones — stock photos will feel off-brand.
**Canonical Brand Image (OG):**
- https://linear.app/static/og/homepage.jpg
*This is the image shown when the site is shared on social media — represents the brand visual essence.*
**Hero Image (above-fold dominant visual):**
- Aspect: 1.79:1 (landscape (16:9-ish))
- Rendered size: 1440×804px
- *Use this aspect ratio + composition for your clone's hero — mimicking the proportion preserves the visual hierarchy.*
**Aspect Ratio Distribution:**
- Landscape (1.15–2.3): 2 (100%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 0 (0%)
**Media Format Mix:**
- SVG: 5 (icons, illustrations, decorative geometry)
**Average rendered image size:** 1428×786px
**Above-fold image count:** 2 / 2
**Decorative Patterns Detected:**
- 1 multi-stop linear gradient (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth
- 3 radial gradients — circular color blooms used for spotlight/glow effects
- 5 large decorative SVG shapes (≥200×200px, non-icon) — likely blob/illustration accents
- 1 background pattern (non-photo url() backgrounds) — textures/illustrations as backdrops
- **Glassmorphism** detected (`backdrop-filter: blur`) — layered transparent surfaces with blur, modern OS-like aesthetic
- **Noise/grain texture** detected — adds tactile film grain to flat backgrounds
**Clone instruction for decorative work:** This is a gradient-rich design — invest in multi-stop CSS gradients (3+ color stops), not solid backgrounds.
**Imagery Guidance for clones:**
- Use vector illustration as the primary visual language — photos will read as off-brand.
- Maintain consistent illustration style (line weight, color palette) across the site.
## 10. Agent Prompt Guide
### Quick Reference
- Background: Jet Black (`#08090a`)
- Primary text: Off-Cream (`#f7f8f8`)
- Accent: Indigo (`#5e6ad2`)
- Border: Dim Gray (`#62666d`)
- Font: Inter Variable
- Body: 16px weight 400
### Example Component Prompts
- "Create a hero section on Jet Black background (#08090a). Headline at 64px Inter Variable weight 510, line-height 1, letter-spacing -1.408px, color #f7f8f8."
- "Create the primary CTA button: `#5e6ad2` background, `#8a8f98` text, 9999px border-radius, 0px 12px padding, 590 weight, Inter Variable font."
- "Design a card on `#0f1011` background. Border: 1px solid rgba(255, 255, 255, 0.05). Radius: 8px. Shadow: none. Padding: 0px 24px 28px."
- "Build navigation: static on `#08090a`. Inter Variable 16px weight 400 for links."
### Iteration Guide
1. **Canvas**: Set the dark canvas to Jet Black (`#08090a`) — every component is composited against this exact base.
2. **Typography**: All type in Inter Variable, weight range 300–680. Never exceed 680 — heavier weights break the brand's tonal restraint.
3. **Accent**: Indigo (`#5e6ad2`) is the sole interactive color. On hover → Accent (`#7170ff`). Use CSS transitions, not opacity/brightness filters.
4. **Focus**: Render focus rings in Indigo (`#5e69d1`) — never hide focus outlines. The ring color is distinct from the accent to avoid ambiguity.
5. **Motion**: All transitions use `cubic-bezier(0.25,0.46,0.45,0.94)`. Timing: 100ms for micro-interactions, 150ms for layout changes. Never use linear for UI transitions — preserve the brand's easing personality.
6. **Shape**: CTAs at `9999px`, cards at `8px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
7. **Spacing**: Use the `--ca-space-*` token scale (6px–32px). All padding, margin, and gap values are multiples from this scale — no magic numbers.
8. **Tokens**: Import from §11 CSS Export (`--ca-*` vars). Never hardcode hex values — always reference a token so theming remains consistent.

**Agent rule**: rebuild sections in this order (sorted by vertical position). Match the layout primitive (grid N-col / flex direction / block).
## 14. Copy Library (Real Content from Source)
*Actual text content extracted from the live page. Use these strings verbatim when reproducing the site — they carry the brand voice.*
```yaml
copy:
section-headings:
- "A new species of product tool. Purpose-built for modern teams with AI workflows at its core, Linear"
- "Make product operations self-driving"
- "Changelog"
- "Built for the future. Available today."
sub-headings:
- "Faster app launch"
- "Product"
ctas:
- "Product"
- "Linear"
- "Inbox"
- "Workspace"
- "Faster app launch"
navigation:
- "Customers"
- "Pricing"
- "Now"
- "Contact"
- "Docs"
- "Open app"
- "Log in"
- "Sign up"
footer-links:
- "Intake"
- "Privacy"
```
**Agent rule**: reuse these exact strings when generating UI. Do NOT translate or rephrase — brand voice is preserved through the original wording.
## 15. Asset Inventory (Image Roles & Ratios)
*Image inventory classified by role and aspect ratio. When reproducing the site, allocate this number of assets per role.*
```yaml
assets:
hero:
count: 1
avg-ratio: 1.84
common-aspect: "~16:9 landscape"
thumbnail:
count: 24
avg-ratio: 1.00
common-aspect: "~1:1 square"
sample-alts:
- "Avatar of Karri"
- "Avatar of Karri"
```
**Agent rule**: when generating placeholder images, match these counts and aspect ratios. Use neutral placeholder backgrounds for `product` (e.g. `#f5f5f5`), full-color photography hints for `hero` and `editorial`.
## 16. Component HTML Templates
*Suggested HTML markup for reproducing the key components — based on what was detected in the source DOM.*
### Button (primary action)
```html
<button class="btn btn-primary">
Product
</button>
```
_Source pattern detected: padding `0px 12px` · radius `9999px` · weight `400`_
**Agent rule**: use these markup skeletons as the structural baseline. Apply tokens from §2-3 for visual styling.
## 12. Known Extraction Gaps
*Auto-detected limitations of this extraction — understand before building:*
- **1 parasitic shadow(s) detected** — colored box-shadows (not near-black) found in allShadows. These likely originate from browser extensions or third-party injected widgets (e.g. Grammarly, chat overlays), not from the site's own design system. Discard them when building.
