--- version: alpha name: solidjs.com description: "Light product system built on #ffffff with #446b9e as the primary CTA accent. Type anchored in Gordita at 36px / weight 600. Extracted automatically from https://solidjs.com/ — rendered styles via getComputedStyle() + CSS custom properties (token-only values may not be painted)." narrative: | solidjs.com is built on a pure-white canvas (rgb(255, 255, 255)). The system uses rgb(68, 107, 158) as the accent for primary actions and brand signals. Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside Gordita as the primary typeface. A layered elevation system (4 distinct shadows) building a clear front-to-back hierarchy. Motion is a first-class concern — 15 keyframe animations plus transition-driven interactions. colors: background: "#ffffff" surface-1: "#ffffff" surface-2: "rgba(226, 232, 240, 0.5)" ink-subtle: "#000955" primary: "#446b9e" on-primary: "#ffffff" primary-hover: "#eab308" hairline: "rgba(100, 116, 139, 0)" typography: display-xl: fontFamily: "Gordita, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 36px fontWeight: 600 lineHeight: 1.11 letterSpacing: 0 display-md: fontFamily: "Gordita, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 20px fontWeight: 600 lineHeight: 1.4 letterSpacing: 0 body: fontFamily: "Gordita, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 16px fontWeight: 400 lineHeight: 1.5 letterSpacing: 0 button: fontFamily: "Gordita, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 15px fontWeight: 400 lineHeight: 1.5 letterSpacing: 0 mono: fontFamily: "Consolas, 'SF Mono', 'JetBrains Mono', Menlo, monospace" fontSize: 15px fontWeight: 400 lineHeight: 1.33 letterSpacing: 0 rounded: none: 0px xs: 4px sm: 8px md: 24px lg: 9999px xl: 10007px pill: 9999px spacing: xxs: 2px xs: 8px sm: 12px md: 20px lg: 40px xl: 48px xxl: 80px components: button-outline: backgroundColor: "{colors.hairline}" textColor: "{colors.primary}" typography: "{typography.body}" rounded: "{rounded.xs}" padding: 0px 12px button-primary-brand: backgroundColor: "{colors.primary-hover}" textColor: "{colors.on-primary}" typography: "{typography.button}" rounded: "{rounded.none}" padding: 12px button-primary-brand-2: backgroundColor: "{colors.primary}" textColor: "{colors.on-primary}" typography: "{typography.body}" rounded: "{rounded.sm}" padding: 12px 20px input-text-input: backgroundColor: "{colors.hairline}" textColor: "{colors.hairline}" typography: "{typography.button}" rounded: "{rounded.none}" extracted_at: "2026-06-11T06:16:37.900Z" completeness: 72 scoreVersion: "v2" --- # Design System — solidjs.com > Extracted automatically by Prism from https://solidjs.com > Date: 2026-06-11 > Viewport: Desktop 1440x900 + Mobile 390x844 > Values are extracted, not hand-written: rendered styles via getComputedStyle() + colors declared in CSS custom properties (token-only values are marked `(token)` and may not be painted). > ⚠️ **LOW-CONFIDENCE CAPTURE** — this extraction likely sampled an app shell / interactive demo, **not** the marketing page.

This is the brand's most recognizable visual — reproduce it, don't replace it with a generic card or flat panel. solidjs.com uses a pure-white canvas (`#ffffff`), letting typography, color and imagery carry the visual weight. Typography is anchored in **Gordita**, deployed with OpenType features enabled globally (`"calt" 0, "liga" 0`). These aren't decorative — they're load-bearing: without them, the typeface reverts to its generic state and the design loses its specific texture. Body text reads in Pure Black (`#000000`) (contrast ratio 21.0:1, well above WCAG AA). **Steel Blue** (`#446b9e`) provides interactive distinction without visual aggression. Elevation is built from multi-layer shadow stacks (4 distinct) — each combines several blurred layers at varying offsets to build a clear front-to-back hierarchy. 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: Pure White (`#ffffff`) - Primary typeface: Gordita - Accent: Steel Blue (`#446b9e`) - Shadow system: 4 distinct elevation levels - Custom fonts loaded: Gordita ## 2.

Typography Rules ### Font Families - **Primary**: `Gordita` - **Secondary**: `codicon` - **Font 3**: `ui-sans-serif` - **Font 4**: `-apple-system` - **Font 5**: `Consolas` ### Custom Fonts Loaded - **Gordita** weight 400 (normal) - **Gordita** weight 700 (normal) - **Gordita** weight 500 (normal) - **Gordita** weight normal (normal) - **Gordita** weight 100 (normal) - **Gordita** weight 600 (normal) - **codicon** weight normal (normal) ### Typography Hierarchy | Role | Font | Size | Weight | Line Height | Letter Spacing | Notes | |------|------|------|--------|-------------|----------------|-------| | Display Hero | Gordita | 36px | 600 | 1.11 | normal | Main headline (h2) | | Sub-heading | Gordita | 20px | 600 | 1.4 | normal | Third-level heading (h3) | | Body | Gordita | 16px | 400 | 1.5 | normal | Standard reading text | | Button | Gordita | 15px | 400 | 1.5 | normal | Button label (15px) | | Input | Consolas | 15px | 400 | 1.33 | normal | Form input (15px) | | Input | Gordita | 14px | 400 | 1.43 | normal | Form input (14px) | ### Full Font Size Scale Sizes detected in the design (descending): `36px`, `30px`, `24px`, `21px`, `20px`, `18px`, `16px`, `15px`, `14px`, `12px`, `8.80px` > 6 size(s) detected outside the sampled hierarchy (30px, 24px, 21px, 18px, 12px, 8.8px). 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: - **contextual alternates** (`calt`) — connections between letters refined contextually - **ligatures** — common letter pairs replaced with refined glyphs (fi, fl, etc.) **Clone instruction:** Enable these in your CSS: ```css body { font-feature-settings: "calt", "liga"; } ``` ## 4. Component Stylings ### Buttons **Outline** - Background: `transparent` `{colors.hairline}` - Text: `#446b9e` `{colors.primary}` - Padding: 0px 12px - Radius: 6px - Border: 1px solid rgb(229, 231, 235) - Font: 16px weight 400 - Use: Secondary action with border **Primary Brand** - Background: `#eab308` `{colors.primary-hover}` - Text: `#ffffff` `{colors.on-primary}` - Padding: 12px - Radius: 0px - Font: 15px weight 400 - Use: Primary CTA / brand action **Primary Brand** - Background: `#446b9e` `{colors.primary}` - Text: `#ffffff` `{colors.on-primary}` - Padding: 12px 20px - Radius: 8px - Font: 16px weight 400 - Use: Primary CTA / brand action **Primary Brand** - Background: `#4f88c6` - Text: `#ffffff` `{colors.on-primary}` - Padding: 12px 20px - Radius: 8px - Font: 16px weight 400 - Use: Primary CTA / brand action **Ghost** - Background: `transparent` `{colors.hairline}` - Text: `#000000` - Padding: 12px 16px - Radius: 4px - Font: 16px weight 400 - Use: Subtle action, toolbar, nav button **Icon Button** - Background: `transparent` `{colors.hairline}` - Text: `#000000` - Padding: 16px 24px 0px 16px - Radius: 6px - Border: 1px solid rgb(229, 231, 235) - Font: 14px weight 400 - Use: Toolbar/UI icons **Subtle** - Background: `rgba(226, 232, 240, 0.5)` `{colors.surface-2}` - Text: `#446b9e` `{colors.primary}` - Padding: 20px - Radius: 8px - Font: 18px weight 400 - Use: Quiet action against page bg ### Inputs & Forms **Text Input** - Background: `transparent` `{colors.hairline}` - Text: `transparent` `{colors.hairline}` - Padding: 0px - Radius: 0px - Border: 0px none rgba(0, 0, 0, 0) - Font: 15px weight 400 - Use: Text fields, search inputs - Focus: outline: `rgb(16, 16, 16) auto 1px` ## 4b. Component Behaviors (State Matrix) ### Interaction State Narrative *State transitions extracted via Playwright simulation — exact values in the YAML matrix below.* ```yaml component-behaviors: button: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(68, 107, 158)" border: "1px solid rgb(229, 231, 235)" input: default: bg: "rgb(255, 255, 255)" fg: "rgb(0, 0, 0)" border: "1px solid rgb(209, 213, 219)" focus: bg: "transparent" fg: "inherit" link: default: bg: "rgb(234, 179, 8)" fg: "rgb(255, 255, 255)" navLink: default: bg: "rgb(234, 179, 8)" fg: "rgb(255, 255, 255)" ``` **Agent usage**: Validate generated components against this matrix. If your output's `:hover` state changes properties not listed here, you are off-brand. ## 4c. Component Vocabulary (Closed System) *This brand uses ONLY the following component vocabulary. Introducing new variants without justification breaks the system's tonal coherence.* ### Buttons - **5 shape(s)** in this system: `Outline`, `Primary Brand`, `Ghost`, `Icon Button`, `Subtle` - **DO NOT introduce new buttons variants** without justification ### Inputs & Forms - **1 shape(s)** in this system: `Text Input` - **DO NOT introduce new inputs & forms variants** without justification ## 5. Layout Principles ### Layout Type **top-nav + content** ### Grid Single column, centered content ### Max Width 1200px ### Spacing System Generous spacing — editorial breathing room | Token | Value | |-------|-------| | xxs | 2px | | xs | 8px | | sm | 12px | | md | 20px | | base | 32px | | lg | 40px | | xl | 48px | | 2xl | 64px | | 3xl | 80px | ### Border Radius Scale | Name | Value | Use | |------|-------|-----| | None | 0px | No rounding | | Xs | 4px | Tiny corners (badges, micro elements) | | Sm | 8px | Buttons, inputs, small elements | | Md | 24px | Cards, containers | | Lg | 9999px | Large rounded elements, pill segments | | Xl | 10007px | Category strips, featured containers | | Full | 9999px | Pills, avatars, circular elements | ### Shape Language | Component | Border Radius | |-----------|---------------| | Buttons | `6px` | | Inputs & Forms | `0px` | | Page Body | `0px` | | Navigation | `0px` | | Primary Input | `0px` | **Shape Personality**: Moderate Rounding — Medium corners (4–12px). Modern SaaS standard, neither sharp nor pill. **Full Radius Spectrum**: 0px, 3px, 4px, 6px, 8px, 24px, full/pill (from `allBorderRadii` scan) ## 5b. Spacing Rhythm Names **Measured section padding**: bands use ~80px internal vertical padding (up to 144px) — **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** | `80px` | Top/bottom of full-bleed hero sections | | **section** | `48px` | Between major bands (color change, content shift) | | **subsection** | `40px` | Within a section, between content groups | | **card** | `20px` | Card padding, list-item spacing | | **compact** | `12px` | Form fields, tight clusters, badge padding | | **micro** | `8px` | 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). **3/8 structural patterns detected.** ### Hero Pattern - **Composition:** split-right-text — Split layout, media-left/text-right — image in left column, heading + body in right column. Less common variant. - **Viewport coverage:** full-viewport hero (≥70% screen height) - **Heading:** "Simple and performant reactivity for building user interfaces." — 36px left-aligned - **Media:** present, positioned left - **CTAs:** 3 (primary: "Get Started") - **Clone instruction:** Reproduce the **split-right-text** layout. Use the heading font-size token at the documented size. Place media left of text. ### Card Grid Pattern - **Card count:** 4 cards detected - **Columns (desktop):** 5-up grid - **Card dimensions:** 280×304px (aspect 0.92:1) - **Gap:** 16px between cards - **Content:** ✓ image - **Image position:** top - **Clone instruction:** Build a 5-column grid (desktop) with cards at ~0.92:1 aspect ratio. Each card has an image at the top. ### Footer Pattern - **Columns:** 1 - **Links:** 0 total - **Height:** 20px - **Includes:** ✗ no newsletter | ✗ no social | - **Clone instruction:** Build a 1-column footer with ~0 links per column. ## 6. Depth & Elevation | Level | Treatment | Use | |-------|-----------|-----| | Flat (Level 0) | No shadow | Page background, content blocks | | Layered (Level 1) |
`rgba(0, 0, 0, 0.25) 0px 25px 50px -12px` | Cards, elevated surfaces | | Inset (Level 2) |
`rgb(239, 242, 246) 1px 0px 0px 0px inset` | Buttons, pressed-state elements | | Layered (Level 3) |
`rgba(106, 115, 125, 0.2) 0px 3px 2px -2px` | Cards, elevated surfaces | | Layered (Level 4) |
`rgba(0, 0, 0, 0.35) 0px 0px 4px 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 | |-------|---------------| | `cubic-bezier(0.4,0,0.2,1)` | Material Standard — Balanced | | `linear` | Linear — No Easing | ### Duration Scale | Value | Tier | Typical Use | |-------|------|-------------| | `100ms` | Fast | Hover states, micro-interactions | | `150ms` | Fast | Hover states, micro-interactions | | `200ms` | Normal | Panel open/close, navigation | | `300ms` | Normal | Panel open/close, navigation | | `500ms` | Slow | Hero animations, page transitions | | `700ms` | Cinematic | Splash, marketing reveals | | `800ms` | Cinematic | Splash, marketing reveals | ### Copy-Paste Transition Snippets **Color / Background** ```css transition: color 0.2s cubic-bezier(0.4, 0, 0.2, 1), background-color 0.2s cubic-bezier(0.4, 0, 0.2, 1), border-color 0.2s cubic-...; ``` **Color / Background** ```css transition: color 0.15s cubic-bezier(0.4, 0, 0.2, 1), background-color 0.15s cubic-bezier(0.4, 0, 0.2, 1), border-color 0.15s cub...; ``` **Transform** ```css transition: transform 0.5s cubic-bezier(0.4, 0, 0.2, 1); ``` **All Props** ```css transition: 0.5s cubic-bezier(0.4, 0, 0.2, 1); ``` ### Keyframe Animation Catalog | Animation Name | Type | Animated Props | Use Hint | |----------------|------|----------------|----------| | `spin` | Rotate / Spin | transform | Loading indicator | | `reveal-delay` | Fade | opacity | UI transition | | `Page-Loading-Bar` | Slide | transform | Loading indicator | | `monaco-cursor-smooth` | Fade | opacity | UI transition | | `monaco-cursor-phase` | Fade | opacity | UI transition | | `monaco-cursor-expand` | Scale | transform | UI transition | | `monaco-findInput-highlight-0` | Color Pulse | background-image, background-position-x, background-position-y, background-size, background-repeat, background-attachment, background-origin, background-clip, background-color | UI transition | | `monaco-findInput-highlight-dark-0` | Color Pulse | background-image, background-position-x, background-position-y, background-size, background-repeat, background-attachment, background-origin, background-clip, background-color | UI transition | | `progress` | Scale | transform | UI transition | | `fadeIn` | Fade | opacity | Element entrance | | `fadeOut` | Fade | opacity | Element exit | | `codicon-spin` | Rotate / Spin | transform | Loading indicator | | `fadein` | Fade | opacity, visibility | Element entrance | ### Motion Fingerprint - **Speed Character**: Deliberate & Calm (median duration: `300ms`) - **Dominant Easing**: custom cubic-bezier curves - **Animation Library**: 13 unique animations (15 total including variants) > This design moves with deliberate & calm timing using custom cubic-bezier curves, creating a UI that feels calm and controlled. ## 8. Do's and Don'ts ### Do - Use Gordita 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 Steel Blue (`#446b9e`) as the primary accent — it's the brand's signature interactive color - Maintain nav height at 64px — 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 - Build the hero as a split layout with media on the right — text and visual share equal weight - Include exactly 3 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 - Use a 5-column grid on desktop — density matters for this content type ### 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 collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence - Don't over-build the footer — this design keeps it minimal (1 cols, 0 links) ## 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(68, 107, 158)` for primary CTAs and brand-mark signals only" why: "Single chromatic assertion device — overuse dilutes meaning" test: "querySelectorAll('[style*=\"rgb(68, 107, 158)\"]').length <= 3 per fold" ``` ## 9. Responsive Behavior ### Breakpoints | Name | Width | Key Changes | |------|-------|-------------| | Mobile Large | 640px | Expanded mobile layout | | Tablet | 768px | Multi-column grids begin | | Tablet | 1024px | Multi-column grids begin | | Desktop | 1280px | Full feature layout | | Large Desktop | 1536px | Maximum content width | ### Token Diff — Desktop vs Mobile | Element | Property | Desktop | Mobile | |---------|----------|---------|--------| | nav | display | `flex` | `block` | | nav | padding | `0px 48px` | `0px 12px` | | button | width | `auto` | `50px` | ### Collapsing Strategy - Navigation: flex → block 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 collapses split-right-text → centered** — the side-by-side layout stacks vertically, with media moving above the text. - **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.* - **Canvas / 2D rendering** — animated/interactive canvas (charts, graphs, particle fields). Reproduce as live data-viz (e.g. an animated SVG/Canvas line chart), NOT a static image. - **WebGL** — GPU 3D/shader graphics (hero atmosphere is rendered, not a flat gradient). - **Clip-path shapes** — 1 non-rectangular cut(s). - **Scroll-driven reveals** — content animates in on scroll (CSS scroll-timeline). Build fade/translate reveal-on-scroll for below-fold bands. > **Motion fingerprint**: WebGL/3D canvas, non-rectangular shapes (1), CSS scroll-driven animations ## 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. **Hero Image (above-fold dominant visual):** - Aspect: 1.71:1 (landscape (16:9-ish)) - Rendered size: 288×168px - *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): 4 (31%) - Portrait (<0.87): 0 (0%) - Square (0.87–1.15): 1 (8%) - Ultra-wide (>2.3): 8 (62%) **Media Format Mix:** - WebP: 5 (optimized photo/illustration hybrid) - SVG: 3 (icons, illustrations, decorative geometry) **Average rendered image size:** 172×78px **Above-fold image count:** 3 / 13 **Decorative Patterns Detected:** - 14 multi-stop linear gradients (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth - 5 background patterns (non-photo url() backgrounds) — textures/illustrations as backdrops **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:** - 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: Pure White (`#ffffff`) - Primary text: Pure Black (`#000000`) - Accent: Steel Blue (`#446b9e`) - Border: Transparent (`transparent`) - Font: Gordita - Body: 16px weight 400 ### Example Component Prompts - "Create the primary CTA button: `#446b9e` background, `#ffffff` text, 9999px border-radius, 12px padding, 600 weight, Gordita font." - "Build navigation: relative on `#ffffff`. Gordita 16px weight 400 for links." ### Iteration Guide 1. **Canvas**: Set the light canvas to Pure White (`#ffffff`) — every component is composited against this exact base. 2. **Typography**: All type in Gordita, weight range 400–600. Never exceed 600 — heavier weights break the brand's tonal restraint. 3. **Accent**: Steel Blue (`#446b9e`) — one accent, applied consistently to CTAs, active states, and links. Never introduce a second saturated color. 4. **Motion**: All transitions use `cubic-bezier(0.4,0,0.2,1)`. Never use linear for UI transitions — preserve the brand's easing personality. 5. **Shape**: CTAs at `0px`. Apply border-radius from the extracted scale only — don't invent intermediate values. 6. **Spacing**: Use the `--ca-space-*` token scale (8px–48px). All padding, margin, and gap values are multiples from this scale — no magic numbers. 7. **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.* ```css /* Colors */ :root { --ca-on-primary: #ffffff; --ca-surface-2: #e2e8f0; --ca-ink-subtle: #000955; --ca-primary: #446b9e; --ca-primary-hover: #eab308; --ca-hairline: transparent; } /* Typography */ :root { --ca-font-primary: "Gordita", system-ui, sans-serif; --ca-text-display: 36px; --ca-text-body: 16px; --ca-text-button: 15px; --ca-text-mono: 15px; } /* Spacing & Radius */ :root { --ca-space-xxs: 2px; --ca-space-xs: 8px; --ca-space-sm: 12px; --ca-space-md: 20px; --ca-space-base: 32px; --ca-space-lg: 40px; --ca-space-xl: 48px; --ca-space-2xl: 64px; --ca-space-3xl: 80px; --ca-radius-none: 0px; --ca-radius-xs: 4px; --ca-radius-sm: 8px; --ca-radius-md: 24px; --ca-radius-lg: 9999px; --ca-radius-xl: 10007px; --ca-radius-full: 9999px; } ``` ## 13. Page Structure Skeleton *The actual layout the source site uses. Reproduce these sections in order to match the site structure.* ```yaml page-skeleton: - section: hero tag: div height: 4795px width: full-bleed layout: block children: 1 contains: chart/canvas (reproduce as live data-viz, not a flat image) - section: header tag: header classes: ["relative", "mx-2", "rounded-br-3xl", "rounded-bl-3xl"] height: 728px width: 1424px layout: block children: 3 bg-treatment: linear-gradient - section: feature-section tag: main height: 4795px width: full-bleed layout: block children: 1 contains: chart/canvas (reproduce as live data-viz, not a flat image) - section: feature-section tag: section classes: ["px-3", "lg:px-12", "container", "space-y-10"] height: 728px width: 1280px layout: block children: 3 vertical-padding: ~144px (airy) padding: "208px 48px 80px" - section: feature-section tag: div classes: ["md:bg-hero", "dark:from-bg-gray-700", "bg-right", "rtl:bg-left"] height: 728px width: 1424px layout: block children: 2 bg-treatment: image vertical-padding: ~144px (airy) padding: "0px 40px" - section: content-section tag: div classes: ["px-0", "lg:px-12", "container", "flex"] height: 504px width: 1280px layout: flex-column justify=normal children: 2 bg-treatment: image padding: "40px 48px 0px" - section: card-grid tag: section classes: ["grid", "sm:grid-cols-2", "lg:grid-cols-4", "space-y-4"] height: 304px width: 1184px layout: grid: 4-col gap=normal children: 4 - section: feature-section tag: div classes: ["lg:my-10", "px-0", "lg:px-12", "container"] height: 2589px width: 1280px layout: flex-column justify=normal children: 5 vertical-padding: ~80px (generous) contains: chart/canvas (reproduce as live data-viz, not a flat image) padding: "0px 48px" - section: section tag: section classes: ["border-2", "m-5", "lg:m-0", "border-gray-200"] height: 88px width: 1184px layout: block children: 1 - section: feature-section tag: section classes: ["grid", "grid-cols-1", "gap-x-16", "xl:grid-cols-[minmax(640px,_12fr)_minmax(0,_11fr)]"] height: 760px width: 1184px layout: grid: 2-col gap=normal 64px children: 2 vertical-padding: ~80px (generous) contains: chart/canvas (reproduce as live data-viz, not a flat image) padding: "80px 32px" - section: feature-section tag: section classes: ["bg-solid-lightgray", "py-16", "grid", "grid-cols-1"] height: 618px width: 1184px layout: grid: 2-col gap=normal children: 1 bg: "rgb(243, 245, 247)" bg-treatment: image vertical-padding: ~64px (generous) padding: "64px" - section: feature-section tag: section classes: ["py-20", "px-10", "lg:px-10", "flex"] height: 579px width: 1184px layout: flex-row justify=normal children: 2 vertical-padding: ~80px (generous) padding: "80px 40px" - section: feature-section tag: section classes: ["bg-solid-lightgray", "rounded-3xl", "grid", "md:grid-cols-2"] height: 384px width: 1184px layout: grid: 2-col gap=normal children: 2 bg: "rgb(243, 245, 247)" vertical-padding: ~80px (generous) padding: "80px" - section: content-section tag: div classes: ["py-10", "mt-5", "bg-solid-lightgray", "rounded-tr-3xl"] height: 810px width: 1424px layout: block children: 1 bg: "rgb(243, 245, 247)" vertical-padding: ~40px padding: "40px 0px" - section: content-section tag: div classes: ["px-7", "md:px-0", "py-10", "lg:px-12"] height: 730px width: 1280px layout: flex-row justify=normal children: 2 vertical-padding: ~40px padding: "40px 48px" ``` **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: - "Simple and performant reactivity for building user interfaces." - "Performance focused" - "on both client and server" - "Fully loaded with all features." sub-headings: - "Performant" - "Familiar and modern" ctas: - "Get Started" - "Intro to Solid (100 seconds)" - "Advanced intro (5 minutes)" - "Documentation" - "Dark mode" - "Visit the Solid Store for stickers, t-shirts and more!" - "main.jsx" - "Import Map" navigation: - "Get Started" - "Intro to Solid (100 seconds)" - "Advanced intro (5 minutes)" - "Documentation" - "SolidStart" - "Playground" - "GitHub" - "Reddit" - "Discord" - "Bluesky" ``` **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: logo: count: 10 avg-ratio: 3.12 common-aspect: "~16:6 banner" sample-alts: - "Coderabbit" - "Informaticon" - "Cloudflare" product: count: 1 avg-ratio: 1.07 common-aspect: "~1:1 square" sample-alts: - "Solid logo" thumbnail: count: 5 avg-ratio: 0.99 common-aspect: "~1:1 square" sample-alts: - "Performant" - "Powerful" - "Pragmatic" ``` **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 ``` _Source pattern detected: padding `12px` · radius `0px` · weight `400`_ **Agent rule**: use these markup skeletons as the structural baseline. Apply tokens from §2-3 for visual styling. ## 17. Content Architecture & Resources (Links by Purpose) *The page's links classified by purpose — the information architecture to reproduce. Categories, featured images, devices and projects are extracted from the rendered DOM, not guessed.* **By purpose:** **nav** 1 · **cta** 1 · **docs** 2 · **social** 6 · **footer** 11 · **other** 13 **Primary actions (conversion path):** - Primary call-to-action — "Get Started" (the conversion path) → `https://docs.solidjs.com/quick-start` **Signals:** 22/34 links carry a featured image · dominant link roles: footer-link (12), content-card (11), inline-link (9). --- ## Extraction Completeness: 72/100 (C) | Category | Score | Max | Detail | |----------|-------|-----|--------| | Colors & Palette | 25 | 25 | 19 named colors | | Typography | 15 | 20 | 6 roles defined | | Components | 8 | 20 | 2 specs extracted | | Motion & Interaction | 12 | 15 | Keyframes | | CSS Custom Properties | 7 | 10 | 142 vars | | Responsive Breakpoints | 5 | 5 | 5 breakpoints | | Variable Fonts | 0 | 5 | None detected | ## 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 (Gordita, codicon)** — detected but not downloaded. Substitute with your licensed copy or a close fallback (see Typography section for metrics). - **Sparse component extraction** — fewer than 5 component types detected. Highly dynamic sections (modals, datepickers, carousels) require interaction to render and are not captured in a static pass. | Category | What's missing | Fallback strategy | |----------|----------------|-------------------| | **Dark mode** | No dark-mode CSS variables or media queries detected | Light mode is canonical; do not generate dark-mode variants unless explicitly requested | ### Per-section confidence | Section | Confidence | Reason | |---------|------------|--------| | §1 Visual Theme | High | Body bg extracted via getComputedStyle() | | §2 Colors | High | 142 CSS vars (semantic naming requires ≥20 for high) | | §3 Typography | High | 6 typography roles inferred | | §4 Components | Low | 2 component variants captured | | §7 Motion | High | Keyframes + transitions | | §8 Do's/Don'ts | High | 18 rules generated; design-decisions.json has evidence per rule | | §9 Responsive | High | 5 breakpoints detected | | §9b Photography | High | 13 images, hero present | ## 11.1 CSS Implementation Guide (CSS Interception Engine v2.15+) *Ready-to-use CSS from Prism's CSS Interception Engine — intercepted directly from the site's CSS files (bypasses CORS).
