description: "Light product system built on #ffffff with #0052ff as the primary CTA accent. Type anchored in CoinbaseDisplay at 80px / weight 400. Extracted automatically from https://coinbase.com/ — rendered styles via getComputedStyle() + CSS custom properties (token-only values may not be painted)."
narrative: |
coinbase.com is built on a pure-white canvas (rgb(255, 255, 255)).
The system uses rgb(0, 82, 255) as the high-saturation accent for primary actions.
Fully-rounded CTAs (100000px) signal a friendly, tactile interaction model alongside CoinbaseDisplay as the primary typeface.
A restrained elevation system (1 distinct shadow) — shadows reserved for the few elements that must lift off the page.
Interactions are smoothed by transitions across many elements, with little or no keyframe animation.

## 0. Design DNA
**Density**: moderate | **Motion**: subtle | **Weight**: medium | **Aesthetic**: soft-rounded
| Dimension | Value | Signal |
|---|---|---|
| Canvas | neutral | `#ffffff` |
| Type posture | sans-led (CoinbaseSans) | "It’s time to take control" |
| Color assertion | dual-accent | #0052ff |
| Whitespace | moderate | section rhythm 48px |
| Interaction | subtle | 1 keyframes, 5 transitions |
| Radius language | soft-pill | from token scale |
**Prism fingerprint**: `neutral-canvas · sans-display · dual-accent · soft-pill · subtle-motion`
> **🤖 TL;DR for AI agents** (read this first — saves you scanning the full doc):
>
> - **Canvas**: `rgb(255, 255, 255)` is the page background. Every component composits against this.
> - **Accent**: `rgb(0, 82, 255)` for primary CTAs ONLY. Never decorative.
> - **Body type**: 16px (token: `typography.body`). Default for ALL text not in a heading role.
> - **Section rhythm**: 48px between major bands. Card padding: 24px.
> - **Default radius**: 16px 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
coinbase.com uses a pure-white canvas (`#ffffff`), letting typography, color and imagery carry the visual weight.
Headlines are set in **CoinbaseDisplay**, a sans-serif display face (the dominant type signature, e.g. "It’s time to take control" at 80px). A second display voice — **CoinbaseSans** (sans) — appears in lower bands (e.g. "It’s time to take control"), used for editorial accent. Body text is set in **CoinbaseSans**.
Body text reads in Pure Black (`#000000`) (contrast ratio 21.0:1, well above WCAG AA). **Bgprimary** (`#0052ff`) is the single high-saturation color in the system — it earns its presence only on interactive elements, making CTAs and links the unmistakable focal points against the otherwise neutral palette. Elevation comes from a small, deliberate set of shadows (1 distinct), each a multi-layer stack — several blurred layers at varying offsets — used sparingly rather than across the whole UI.
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: Bglineinverse (`#ffffff`)
- Primary typeface: CoinbaseDisplay
- Accent: Bgprimary (`#0052ff`)
- Display: 80px weight 400
- Shadow system: 1 distinct elevation levels
- Custom fonts loaded: CoinbaseDisplay, CoinbaseSans, CoinbaseText, CoinbaseMono, CoinbaseCondensed

- **DO NOT introduce new cards & containers variants** without justification
### Inputs & Forms
- **1 shape(s)** in this system: `Text Input`
- **DO NOT introduce new inputs & forms variants** without justification
### CTA Banners
- **1 shape(s)** in this system: `Full-width CTA`

### Tabs
- **1 shape(s)** in this system: `Pill Tab`
- **DO NOT introduce new tabs variants** without justification
## 5. Layout Principles
### Layout Type
**top-nav + content**
### Grid
Single column, centered content
### Max Width
1200px
### Spacing System
Compact spacing — information density prioritized
| Token | Value |
|-------|-------|
| xxs | 2px |
| xs | 4px |
| sm | 8px |
| md | 12px |
| base | 16px |
| lg | 24px |
| xl | 32px |
| 2xl | 48px |
| 3xl | 64px |
### Border Radius Scale
| Name | Value | Use |
|------|-------|-----|
| None | 0px | No rounding |
| Xs | 12px | Tiny corners (badges, micro elements) |
| Sm | 16px | Buttons, inputs, small elements |
| Md | 24px | Cards, containers |
| Lg | 32px | Large rounded elements, pill segments |
| Xl | 40px | Category strips, featured containers |
| Full | 100000px | Pills, avatars, circular elements |
### Shape Language
| Component | Border Radius |
|-----------|---------------|
| Buttons | `9999px` |
| Cards & Containers | `56px` |
| Inputs & Forms | `0px` |
| CTA Banners | `0px` |
| Tabs | `56px` |
| Page Body | `0px` |
| Navigation | `0px` |
| Primary Input | `0px` |
**Shape Personality**: Sharp + Pill Contrast — Angular precision with pill-shaped accents (status badges, tags). Creates strong visual hierarchy.
**Full Radius Spectrum**: 12px, 16px, 24px, 32px, 40px, 56px (from `allBorderRadii` scan)
## 5b. Spacing Rhythm Names
**Measured section padding**: bands use ~64px internal vertical padding (up to 80px) — **generous**. (Distinct from the gap *between* sections above.) Reproduce this generous vertical breathing room; cramped spacing is the #1 tell of a cheap clone.
*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** | `12px` | Card padding, list-item spacing |
| **compact** | `8px` | Form fields, tight clusters, badge padding |
| **micro** | `4px` | 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:** left-aligned —
- **Viewport coverage:** full-viewport hero (≥70% screen height)
- **Heading:** "It’s time to take control" — 80px left-aligned
- **Subheading:** "The next Coinbase System Update livestream is coming June 16."
- **CTAs:** 1 (primary: "Learn more")
- **Clone instruction:** Reproduce the **left-aligned** layout. Use the heading font-size token at the documented size. Pair the centered text with the hero’s decorative visual (gradient / SVG / hero image — see §9b), not bare text.
### Navigation Pattern
- **Position:** static (scrolls with page)
- **Layout:** unknown — Layout not classified
- **Height:** 44px
- **Logo:** ✓ present
- **Nav links:** 1 primary items
- **CTAs in nav:** 0 (no buttons — links only)
- **Clone instruction:** Build a static unknown navigation. Link-only — no button styling needed.
### Card Grid Pattern
- **Card count:** 5 cards detected
- **Columns (desktop):** 5-up grid
- **Card dimensions:** 262×896px (aspect 0.29:1)
- **Gap:** 16px between cards
- **Content:** ✗ no image
- **Clone instruction:** Build a 5-column grid (desktop) with cards at ~0.29:1 aspect ratio. Text/icon-only cards (no photography).
### CTA Banner Pattern
- **Banner count:** 13
- **Position:** multiple
- **Visual treatment:** ✓ contrasting background
- **Primary CTA text:** "Explore staking options"
- **Clone instruction:** Place multiple CTA banners across page sections. Use contrasting solid background.
### Footer Pattern
- **Columns:** 1
- **Links:** 81 total
- **Height:** 1230px
- **Includes:** ✗ no newsletter | ✓ social icons | ✓ copyright
- **Clone instruction:** Build a 1-column footer with ~81 links per column, social media links, and a copyright line.
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Layered (Level 1) | <br>`rgba(0, 0, 0, 0.12) 0px 8px 12px 0px` | Cards, elevated surfaces |
**Shadow Philosophy**: Multi-layered shadow system creating natural, atmospheric depth. Each shadow level combines multiple layers for realistic elevation.
## 7. Motion & Interaction
### Dominant Easing Curves
| Curve | Semantic Name |
|-------|---------------|
| `ease-in-out` | Ease In-Out — Symmetric |
| `ease-in` | Ease In — Accelerating |
| `ease` | CSS ease — Default |
### Duration Scale
| Value | Tier | Typical Use |
|-------|------|-------------|
| `200ms` | Normal | Panel open/close, navigation |
### Copy-Paste Transition Snippets
**Background**
```css
transition: background-color 0.2s ease-in-out;
```
**All Props**
```css
transition: text-decoration-color 0.2s ease-in-out;
```
**Opacity**
```css
transition: opacity 0.2s ease-in-out;
```
**Shadow**
```css
transition: box-shadow 0.2s ease-in-out;
```
### Keyframe Animation Catalog
| Animation Name | Type | Animated Props | Use Hint |
|----------------|------|----------------|----------|
| `onetrust-fade-in` | Fade | opacity | Element entrance |
### Motion Fingerprint
- **Speed Character**: Balanced Pacing (median duration: `200ms`)
- **Dominant Easing**: symmetric in-out (precise)
- **Animation Library**: 1 unique animation (1 total including variants)
> This design moves with balanced pacing timing using symmetric in-out (precise), creating a UI that feels natural and fluid.
## 8. Do's and Don'ts
### Do
- Use CoinbaseSans as the primary typeface — it defines the brand personality
- Keep font weights between 400-600 — the system uses a narrow weight range for subtle hierarchy
- 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 Bgprimary (`#0052ff`) as the primary accent — it's the brand's signature interactive color
- Use 56px border-radius on primary buttons — the brand uses generously-rounded CTAs
- Apply 32px padding inside cards — matches the design system's content breathing room
- Use 56px border-radius on cards — consistent with the grid card corners
- Maintain nav height at 44px — consistent vertical space for the navigation bar
- Transition button background to Translucent Bgsecondaryhovered (88%) (`rgba(229, 231, 234, 0.88)`) on hover — this is the extracted interactive state
- Respect the 4px–32px spacing range — the design uses a wide scale for visual breathing room
- Make the hero full-viewport (≥70% screen height) — this design uses an immersive hero, not a tall navbar
- Use a single primary CTA in the hero — the design intentionally avoids choice paralysis
- Use a 5-column grid on desktop — density matters for this content type
- Repeat the primary CTA across 13 banner sections — conversion paths are layered, not single
### Don't
- Don't substitute with generic sans-serif or serif — the custom font carries the brand
- Don't use weight 700 (bold) or above — 600 is the maximum weight in this system
- 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 sharp-cornered or pill buttons — 56px is the CTA border-radius standard
- Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence
- Don't use opacity or brightness filter for button hover — the design uses an explicit background color change
- Don't make the nav sticky — this design lets it scroll away to maximize content focus
- Don't put a CTA button in the nav — this design uses links only at the top
## 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(255, 255, 255)` as the base canvas"
why: "Every component is designed to composit against this exact tone"
test: "document.body.style.backgroundColor === 'rgb(255, 255, 255)'"
- id: brand-accent-001
type: do
rule: "Reserve `rgb(0, 82, 255)` for primary CTAs and brand-mark signals only"
why: "Single chromatic assertion device — overuse dilutes meaning"
test: "querySelectorAll('[style*=\"rgb(0, 82, 255)\"]').length <= 3 per fold"
```
## 9. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 400px | Single column, compact spacing |
| Mobile Large | 500px | Expanded mobile layout |
| Mobile Large | 640px | Expanded mobile layout |
| Mobile Large | 767px | Expanded mobile layout |
| Tablet | 1024px | Multi-column grids begin |
| Desktop | 1279px | Full feature layout |
| Large Desktop | 1439px | Maximum content width |
### Token Diff — Desktop vs Mobile
| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `80px` | `52px` |
| heading | line-height | `80px` | `52px` |
| button | padding | `12px 24px` | `0px` |
| button | width | `136px` | `44px` |
| card | padding | `32px` | `16px` |
| card | border-radius | `56px` | `40px` |
| card | width | `560px` | `358px` |
### Collapsing Strategy
- Headlines: 80px → 52px 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: 12px 24px 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):
- **Card grid: 5-up → 1-up** — cards stack as viewport narrows, becoming a vertical list on mobile.
## 7c. Visual Effects & Dynamic Behavior
*The live/dynamic layer beyond static CSS — reproduce these, not flat substitutes. This is often what separates a faithful clone from a wireframe.*
- **Glassmorphism** — 5 frosted/blur layer(s) (e.g. `blur(5px)`).
> **Motion fingerprint**: glassmorphism (5 layers)
## 9b. Visual Tone & Photography
**Tone:** Mixed photography + illustration
A balanced mix of photographic content and vector graphics. Photos likely carry product/lifestyle context while SVG handles icons, logos, and decorative accents.
**Canonical Brand Image (OG):**
- https://images.ctfassets.net/o10es7wu5gm1/4d4ltl5F5MGyXreHOCtl6e/c4ba702cd30906f2d09339147163f2da/FR.png
*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: 1.33:1 (landscape)
- Rendered size: 632×474px
- Alt text: "hand touching coins"
- *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): 6 (60%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 4 (40%)
**Media Format Mix:**
- JPG: 1 (typically photographic content)
- WebP: 1 (optimized photo/illustration hybrid)
- PNG: 8 (logos, transparent UI elements, mockups)
**Average rendered image size:** 348×283px
**Above-fold image count:** 5 / 10
**Decorative Patterns Detected:**
- **Glassmorphism** detected (`backdrop-filter: blur`) — layered transparent surfaces with blur, modern OS-like aesthetic
**Clone instruction for decorative work:** Glassmorphism is a brand signature — use `backdrop-filter: blur(20px)` on overlapping surfaces.
**Imagery Guidance for clones:**
- Mix photography and illustration intentionally: photos for product/context, vectors for icons + decorative accents.
- Respect the format split — replacing JPGs with illustrations (or vice versa) will shift the brand tone.
## 10. Agent Prompt Guide
### Quick Reference
- Background: Bglineinverse (`#ffffff`)
- Primary text: Pure Black (`#000000`)
- Accent: Bgprimary (`#0052ff`)
- Border: Fgmuted (`rgba(91, 97, 110, 0.2)`)
- Font: CoinbaseSans
- Body: 16px weight 400
### Example Component Prompts
- "Create a hero section on Bglineinverse background (#ffffff). Headline at 80px CoinbaseSans weight 400, line-height 1, color #000000."
- "Create the primary CTA button: `#0052ff` background, `#ffffff` text, 56px border-radius, 0px 24px padding, 600 weight, CoinbaseSans font."
- "Design a card on `#f7f8f9` background. Border: none. Radius: 56px. Shadow: none. Padding: 32px."
- "Build navigation: static on `#ffffff`. CoinbaseSans 16px weight 400 for links."
### Iteration Guide
1. **Canvas**: Set the light canvas to Bglineinverse (`#ffffff`) — every component is composited against this exact base.
2. **Typography**: All type in CoinbaseSans, weight range 400–600. Never exceed 600 — heavier weights break the brand's tonal restraint.
3. **Accent**: Bgprimary (`#0052ff`) is the sole interactive color. On hover → M Tricolor Blue (`#0667d0`). Use CSS transitions, not opacity/brightness filters.
4. **Shape**: CTAs at `9999px`, cards at `56px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
5. **Spacing**: Use the `--ca-space-*` token scale (4px–32px). All padding, margin, and gap values are multiples from this scale — no magic numbers.
6. **Tokens**: Import from §11 CSS Export (`--ca-*` vars). Never hardcode hex values — always reference a token so theming remains consistent.
## 11. CSS Design Tokens Raw Export
*Copy-paste ready `:root {}` block — all values extracted directly from the live site.*

**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:
- "Earn up to 13% APY on your crypto"
- "Explore crypto like Bitcoin, Ethereum, and Dogecoin."
- "The more you trade the less you pay with Advanced Trade"
- "The most trusted crypto broker"
sub-headings:
- "Explore more crypto"
- "The largest public crypto company"
ctas:
- "Individuals"
- ""
- "Sign in"
- "Sign up"
- "Learn more"
- "Explore staking options"
- "See more assets"
- "Tradable"
navigation:
- "Skip to content"
- "Skip to site index"
- "Get up to €150 for getting started¹"
- "Cryptocurrencies"
- "Sign in"
- "Sign up"
footer-links:
- "About"
```
**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:
product:
count: 4
avg-ratio: 1.00
common-aspect: "~1:1 square"
sample-alts:
- "Event 2026 navigation upsell"
- "Coinbase business"
thumbnail:
count: 14
avg-ratio: 1.00
common-aspect: "~1:1 square"
sample-alts:
- "Coinbase Logo"
- "Bitcoin"
- "Ethereum"
```
**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">
Individuals
</button>

## 12. Known Gaps & Confidence
Explicit list of what this extraction could NOT capture. Agents should not invent values for these — either skip the feature or use the documented baseline + heuristic fallback.
*Auto-detected extraction limitations — understand before building:*
- **Licensed web fonts (CoinbaseDisplay, CoinbaseSans, CoinbaseText)** — detected but not downloaded. Substitute with your licensed copy or a close fallback (see Typography section for metrics).
*✅ No critical extraction gaps detected — high-confidence reproduction expected.*
### Per-section confidence
| Section | Confidence | Reason |
|---------|------------|--------|
| §1 Visual Theme | High | Body bg extracted via getComputedStyle() |
| §2 Colors | High | 837 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | High | 5 typography roles inferred |
| §4 Components | High | 5 component variants captured |
| §7 Motion | High | Keyframes + transitions |
| §8 Do's/Don'ts | High | 25 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | High | 7 breakpoints detected |

### Keyframe Animations (Intercepted from CSS)
**3 @keyframes found** — these are the real animation definitions:
```
@keyframes spin-indeterminateProgressCircleCss-iqcdca3 { ... }
@keyframes spin-baseCss-bggfp25 { ... }
@keyframes onetrust-fade-in { ... }
```
<details><summary>Full keyframes CSS (3 animations)</summary>
```css
@keyframes spin-indeterminateProgressCircleCss-iqcdca3{0%{transform:rotate(0)}

@keyframes onetrust-fade-in{0%{opacity:0}100%{opacity:1}}
```
</details>
### Brand Gradient Palette
**2 complex gradients captured** from the site's CSS. The first few are the most prominent visual decorations:
```css
/* Gradient 1 */
background: linear-gradient(to right,currentColor 50%,var(--color-transparent);
/* Gradient 2 */
background: linear-gradient(to left,currentColor 50%,var(--color-transparent);
```
### Hover State CSS (Intercepted)
**2 hover rule lines** captured from CSS files. Key interactive transitions from real CSS (not inferred):
```css

## 11.2 Measured Reality (CDP Engine)
Captured directly from Chrome's engine across **all 3547 rendered nodes** — not a sample. These are the values the page *actually paints*, weighted by how often they appear.
### Real Responsive Breakpoints
**19 breakpoints** read from the live `@media` rules (not guessed) — 14 most relevant:
`400px` · `410px` · `425px` · `426px` · `500px` · `530px` · `550px` · `560px` · `576px` · `600px` · `640px` · `767px` · `768px` · `896px` … (+5 more)
### Measured Design Scale
**Type scale by usage** (× = paint count): `16px`×1359 · `28px`×1158 · `18px`×617 · `14px`×261 · `20px`×98 · `13px`×13 · `36px`×12 · `44px`×9
**Radius scale** (× = paint count): `16px`×68 · `56px`×34 · `12px`×32 · `24px`×7 · `32px`×5 · `40px`×5
**Weights** (× = paint count): `400`×3228 · `600`×309 · `700`×7
**Layout gaps** (× = paint count): `16px`×128 · `12px`×61 · `8px`×40 · `24px`×24 · `48px`×15 · `16px 32px`×5 · `80px`×3 · `4px`×2
**Elevation (real shadows)**:
```css
rgba(0, 0, 0, 0.12) 0px 8px 12px 0px
```
### Provenance — measured styles on key elements
Read from the live CSSOM (includes runtime-injected CSS). This is *what actually styles the page*, by element:
```css
body { font-family:CoinbaseSans, -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", "Helvetica Neue", sans-serif; font-weight:400 }
nav { gap:var(--space-0_5) }
h1 { font-size:2em }
h2 { color:var(--color-fgMuted) }
h2 { font-family:var(--fontFamily-headline) }
h2 { font-size:var(--fontSize-headline) }
h2 { font-weight:var(--fontWeight-headline) }
button { font-family:inherit; font-size:100% }
button { color:var(--color-fgInverse) }
button { border-radius:var(--borderRadius-900) }
button { background-color:var(--inter-bg) }
button { font-weight:600 }
```
> Selectors normalised to their semantic element — source class names are often build-hashed (`.bgDIHX`) and not reusable. The declarations + CSS vars are the transferable part.
