--- version: alpha name: Mintlify-design-analysis description: Mintlify presents documentation infrastructure with a dual-mode aesthetic — atmospheric sky-gradient marketing heroes (cloud illustration backdrops, soft cream-to-blue washes) paired with dense developer-grade documentation surfaces. The system uses Inter for UI prose, Geist Mono for code, and a signature Mintlify green ({colors.brand-green}) reserved for accent CTAs and active states. Black-pill primary buttons dominate marketing, white-on-dark inversions appear on dark hero bands, and a 3-column documentation layout (sidebar / prose / TOC) anchors the developer experience. Coverage spans homepage, startups program, pricing comparison, and the live tabs documentation page. colors: primary: "#0a0a0a" on-primary: "#ffffff" brand-green: "#00d4a4" brand-green-deep: "#00b48a"

The home and startups pages open with cinematic atmospheric heroes — soft sky-gradient backdrops with cloud illustrations on the homepage, dark teal-to-mint gradients with a rocket launch on the startups page — that feel more like a SaaS landing aesthetic than a developer tool. Then the deeper surfaces (pricing comparison, live documentation pages) collapse into dense, high-information layouts where Inter body type carries 14–16px copy across long-form prose, syntax-highlighted code blocks, and 3-column documentation grids. The brand's signature mint green ({colors.brand-green}) appears sparingly but decisively — on the hero "Get started" pill button, the green checkmark icons inside feature lists, the "Featured" pricing tier border, and active state indicators inside docs UI. Black-pill primary buttons dominate the marketing flow; white-on-dark inversions appear on dark hero bands. The signature pairing of Inter (body, headings) with Geist Mono (code blocks, inline references, type signatures) reinforces the developer-tool DNA without requiring a third typeface. **Key Characteristics:** - Atmospheric gradient hero bands (sky-blue to cream on homepage; teal-to-mint on startups) provide cinematic marketing presentation - Signature Mintlify mint green ({colors.brand-green}) reserved for accent CTAs, active states, and feature confirmations - Black-pill primary buttons ({colors.primary} + `{rounded.full}`) for marketing CTAs - Inter for all UI prose; Geist Mono for code blocks, inline code, and type/property signatures - 3-column documentation layout (sidebar / prose / TOC) with dense 14px body type for long-form developer reading - Tightly-controlled radius scale: marketing uses `{rounded.lg}` (12px), pill buttons use `{rounded.full}` — no in-between corner softening - Vibrant testimonial card (`{colors.testimonial-orange}`) breaks color rhythm intentionally for emotional impact ## Colors > Source pages: mintlify.com/ (homepage), /startups (program page), /pricing (comparison), /docs/components/tabs (live documentation). Token coverage was identical across all four pages. ### Brand & Accent - **Mintlify Mint** ({colors.brand-green}): Signature accent — used on hero "Get started" pill button, green checkmarks in feature lists, featured pricing tier border accent, sidebar active indicator dots. - **Deep Mint** ({colors.brand-green-deep}): Pressed/active variant of the mint accent. - **Soft Mint** ({colors.brand-green-soft}): Subtle background tint for success states and confirmation surfaces. - **Brand Tag** ({colors.brand-tag}): Documentation tag and reference color (used in `` JSX-style annotations and code-tag chips). - **Brand Annotate** ({colors.brand-annotate}): Inline code annotation green (used in twoslash code annotation system). - **Brand Warn** ({colors.brand-warn}): Code warning highlight (deprecated, caution). - **Brand Error** ({colors.brand-error}): Red used for required-field labels and error highlight. - **Testimonial Orange** ({colors.testimonial-orange}): Warm coral-orange used on the "Cursor" testimonial card and warm callout surfaces. ### Surface - **Canvas White** ({colors.canvas}): Primary page and card background. - **Canvas Dark** ({colors.canvas-dark}): Promo banner, dark inversion surfaces, code editor wrapper. - **Surface** ({colors.surface}): Subtle section backgrounds, search-pill rest, code-inline background, sidebar active state. - **Surface Soft** ({colors.surface-soft}): Quieter section backgrounds and FAQ accordion. - **Surface Code** ({colors.surface-code}): Dark code-block wrapper background. - **Hairline** ({colors.hairline}): 1px borders and primary dividers. - **Hairline Soft** ({colors.hairline-soft}): Quieter table-row dividers and secondary section breaks. ### Hero Atmospheric - **Hero Sky From / To** ({colors.hero-sky-from}, {colors.hero-sky-to}): Atmospheric sky-blue to soft cream gradient on the homepage hero. - **Hero Dark From / To** ({colors.hero-dark-from}, {colors.hero-dark-to}): Dark teal to mint gradient on the startups hero. ### Text - **Ink** ({colors.ink}): Primary headlines and CTA text. - **Charcoal** ({colors.charcoal}): Body text, code-inline foreground. - **Slate** ({colors.slate}): Secondary text and metadata. - **Steel** ({colors.steel}): Tertiary text, table headers, sidebar inactive items, footer links. - **Stone** ({colors.stone}): Captions, twoslash cursor color, muted labels. - **Muted** ({colors.muted}): De-emphasized labels and disabled text. - **On Dark** ({colors.on-dark}): White text on dark surfaces (hero bands, code blocks, promo banner). - **On Dark Muted** ({colors.on-dark-muted}): Reduced-opacity white for code-block headers and metadata on dark. ### Semantic - Error tones derive from `{colors.brand-error}` for input borders, required-field labels, and validation messaging. ## Typography ### Font Family **Inter** (primary): Variable typeface optimized for UI legibility. Used across every UI surface — body, headings, navigation, button labels, captions. Fallbacks: -apple-system, BlinkMacSystemFont, 'Segoe UI', sans-serif. **Geist Mono** (code): Monospace typeface used inside code blocks, inline code references, type signatures (e.g. `string`, `number`, `boolean`), and property names in API documentation. Fallbacks: 'SF Mono', Menlo, Consolas, 'Geist Mono Fallback', monospace. The brand uses no italic variants of either face — emphasis comes from weight (500/600), color shift, or background highlighting (in code references). ### Hierarchy | Token | Size | Weight | Line Height | Letter Spacing | Use | |---|---|---|---|---|---| | `{typography.hero-display}` | 72px | 600 | 1.05 | -2px | Marketing hero display ("The intelligent Knowledge Platform") | | `{typography.display-lg}` | 56px | 600 | 1.10 | -1.5px | Major section opener ("Built for the intelligence age") | | `{typography.heading-1}` | 48px | 600 | 1.10 | -1px | Page-level headlines ("Pricing on your terms") | | `{typography.heading-2}` | 36px | 600 | 1.20 | -0.5px | Section headlines ("Apply to the Mintlify startup program") | | `{typography.heading-3}` | 28px | 600 | 1.25 | 0 | Subsection headers, "Tabs" docs page title | | `{typography.heading-4}` | 22px | 600 | 1.30 | 0 | Card titles, larger feature headers | | `{typography.heading-5}` | 18px | 600 | 1.40 | 0 | Smaller feature headers, FAQ question titles | | `{typography.subtitle}` | 18px | 400 | 1.50 | 0 | Hero subtitle, lead body | | `{typography.body-md}` | 16px | 400 | 1.50 | 0 | Primary body text | | `{typography.body-md-medium}` | 16px | 500 | 1.50 | 0 | Body emphasis | | `{typography.body-sm}` | 14px | 400 | 1.50 | 0 | Secondary body, table cells, navigation | | `{typography.body-sm-medium}` | 14px | 500 | 1.50 | 0 | Active sidebar nav, button labels, tab labels | | `{typography.caption}` | 13px | 400 | 1.40 | 0 | Helper text, fine print, code-block headers | | `{typography.caption-bold}` | 13px | 600 | 1.40 | 0 | Badge labels | | `{typography.micro}` | 12px | 500 | 1.40 | 0 | Footer microcopy, label chips | | `{typography.micro-uppercase}` | 11px | 600 | 1.40 | 0.5px | Sidebar section headers, "REQUIRED" labels | | `{typography.button-md}` | 14px | 500 | 1.30 | 0 | Pill button labels | | `{typography.code-md}` | 14px | 400 | 1.50 | 0 | Code block content | | `{typography.code-sm}` | 13px | 400 | 1.40 | 0 | Smaller code, type signatures | | `{typography.code-inline}` | 13px | 500 | 1.30 | 0 | Inline `` references in body | ### Principles - **Tight hero leading** (1.05) creates magazine-grade display headlines on the 72px hero - **Negative letter-spacing** progresses inversely with size — display sizes use -2px to -1.5px; smaller headings relax to 0 - **Documentation-grade body** (1.50 line-height on 14–16px) ensures comfortable long-form reading in dense docs surfaces - **Inter / Geist Mono pairing** — Inter for everything else, Geist Mono surgically for code references; the contrast between the two is the brand's developer-respect signal - **Uppercase micro labels** with +0.5px letter-spacing carry sidebar section headers and "REQUIRED" annotation tags ## Layout ### Spacing System - **Base unit**: 4px (8px primary increment) - **Tokens**: `{spacing.xxs}` (4px) · `{spacing.xs}` (8px) · `{spacing.sm}` (12px) · `{spacing.md}` (16px) · `{spacing.lg}` (20px) · `{spacing.xl}` (24px) · `{spacing.xxl}` (32px) · `{spacing.xxxl}` (40px) · `{spacing.section-sm}` (48px) · `{spacing.section}` (64px) · `{spacing.section-lg}` (96px) · `{spacing.hero}` (120px) - **Section rhythm**: Marketing pages use `{spacing.section-lg}` (96px) between major bands; pricing comparison tightens to `{spacing.section}` (64px); documentation surfaces use `{spacing.xxl}` (32px) between subsections - **Card internal padding**: Standard `{spacing.xl}` (24px) for compact cards; `{spacing.xxl}` (32px) for pricing cards and feature panels; testimonial card pushes to `{spacing.section}` (64px) for hero-card presence ### Grid & Container - Marketing pages use a 1280px max-width with 32px gutters - Hero and feature bands often use 2-column splits (text left, illustration/mockup right) - Pricing page renders 3 tier cards in a row at desktop (FREE / Lift Off / Custom), then a comprehensive feature comparison table below - Documentation pages use a strict 3-column grid: left sidebar nav (~240px), center prose (~720px max-width), right TOC (~200px) - Logo walls use 6-up rows of customer logos at 80–100px height each ### Whitespace Philosophy Marketing surfaces give content generous breathing room — `{spacing.hero}` (120px) above-the-fold creates space for atmospheric gradient backdrops to read clearly. Documentation tightens dramatically: section gaps drop to `{spacing.xxl}` (32px), table rows pack to `{spacing.md}` (16px), sidebar nav compresses to `{spacing.xs}` (8px) vertical rhythm. ## Elevation & Depth The system runs predominantly flat with strategic atmospheric depth. | Level | Treatment | Use | |---|---|---| | 0 (flat) | No shadow; `{colors.hairline}` border | Default cards, table rows, form inputs | | 1 (subtle) | `rgba(0, 0, 0, 0.04) 0px 1px 2px 0px` | Hover-elevated tiles, subtle highlights | | 2 (card) | `rgba(0, 0, 0, 0.08) 0px 4px 12px 0px` | Standard feature cards | | 3 (mockup) | `rgba(0, 0, 0, 0.12) 0px 24px 48px -8px` | Hero product mockup framing — the deep diffuse drop on the homepage hero docs preview | | 4 (brand-tinted) | `rgba(0, 212, 164, 0.08) 0px 8px 24px` | Featured pricing tier glow | ### Decorative Depth - The homepage hero uses an atmospheric photographic backdrop (cloud illustration on sky-gradient) for depth — no shadow needed; the imagery does the work - The startups hero uses a similar treatment with a rocket-launch illustration cutting across the dark teal gradient - Code blocks carry their own internal depth via syntax-highlighting color hierarchy on the dark surface; no shadow used ## Shapes ### Border Radius Scale | Token | Value | Use | |---|---|---| | `{rounded.xs}` | 4px | Inline code chips, micro tags | | `{rounded.sm}` | 6px | Sidebar nav items, type badges | | `{rounded.md}` | 8px | Inputs, search pill, code blocks, secondary cards | | `{rounded.lg}` | 12px | Standard cards, pricing tiers, hero mockup, FAQ items | | `{rounded.xl}` | 16px | Larger feature panels | | `{rounded.xxl}` | 24px | Featured product showcase tiles | | `{rounded.full}` | 9999px | All buttons, pill tabs, badges | The radius scale is tightly disciplined — the brand never uses a corner softening between `{rounded.md}` (8px) and `{rounded.lg}` (12px) for the same component family. Pill buttons (`{rounded.full}`) are used universally; rectangular cards use `{rounded.lg}` (12px) consistently. ### Photography Geometry - Hero illustrations (cloud, rocket) sit on full-bleed gradient backdrops with no internal framing - Customer logo walls use 1:1 ratio cells without rounding (logos are presented inline as wordmarks) - Testimonial photos use 1:1 aspect with `{rounded.md}` (8px) softening - Code editor mockup hero image uses `{rounded.lg}` (12px) corners on a hairline-bordered card with a deep diffuse drop shadow ## Components > Per the no-hover policy, hover states are NOT documented. Default and pressed/active states only. ### Buttons **`button-primary`** — Black pill primary CTA, the dominant action across all surfaces. - Background `{colors.primary}`, text `{colors.on-primary}`, typography `{typography.button-md}`, padding `10px 20px`, rounded `{rounded.full}`. - Pressed state `button-primary-pressed` lifts to `{colors.charcoal}`. - Disabled state `button-primary-disabled` uses `{colors.hairline}` background and `{colors.muted}` text. **`button-accent-green`** — Mint green pill for brand-emphasis CTAs (hero "Get started", featured pricing CTA). - Background `{colors.brand-green}`, text `{colors.primary}`, typography `{typography.button-md}`, padding `10px 20px`, rounded `{rounded.full}`. **`button-on-dark`** — White pill for use on dark hero bands (startups page "Get started"). - Background `{colors.on-dark}`, text `{colors.primary}`, typography `{typography.button-md}`, padding `10px 20px`, rounded `{rounded.full}`. **`button-secondary`** — Outlined pill for secondary actions. - Background transparent, text `{colors.ink}`, border `1px solid {colors.hairline}`, typography `{typography.button-md}`, padding `10px 20px`, rounded `{rounded.full}`. **`button-ghost`** — Quieter rectangular ghost button (sidebar action, tertiary nav). - Background transparent, text `{colors.ink}`, typography `{typography.button-md}`, padding `8px 12px`, rounded `{rounded.md}`. **`button-link`** — Inline text link styled as a subtle button. - Background transparent, text `{colors.ink}`, typography `{typography.body-sm-medium}`, padding `0`. Underline appears on activation. **`button-icon-circular`** — 32×32px circular utility button (close, copy, arrow). - Background `{colors.canvas}`, text `{colors.ink}`, border `1px solid {colors.hairline}`, rounded `{rounded.full}`. ### Cards & Containers **`card-base`** — Standard documentation/feature card. - Background `{colors.canvas}`, rounded `{rounded.lg}`, padding `{spacing.xl}`, border `1px solid {colors.hairline}`. **`card-feature`** — Feature panel on light gray surface. - Background `{colors.surface}`, rounded `{rounded.lg}`, padding `{spacing.xxl}`. **`card-help`** — "Need help?"

Hero scales to 36px. Pill nav collapses to hamburger. Pricing tiers stack 1-up. Footer 1-column accordion. | | Mobile (large) | 480 – 767px | Same as small but feature tiles render 2-up. Hero scales to 44px. | | Tablet | 768 – 1023px | 2-column feature grids. Pill-tab nav returns. Documentation sidebar collapses to drawer. Hero scales to 56px. | | Desktop | 1024 – 1279px | Full 3-column docs grid (sidebar / body / TOC). 3-tier pricing card row. Hero at 72px. | | Wide Desktop | ≥ 1280px | Wider hero gutters, larger product mockup, fixed 240px sidebar. | ### Touch Targets - Pill buttons render at 36–40px effective height — bumps to 44px on mobile via padding override - Circular icon buttons: 32×32px desktop → 44×44px mobile - Form inputs render at 40px height; bumps to 44px mobile - Sidebar nav items render at ~32px tall — bump to 44px mobile drawers ### Collapsing Strategy - **Promo banner** stays full-width; truncates at < 480px - **Top nav** below 1024px collapses to hamburger; horizontal links move into drawer - **Hero band**: 2-column hero (text + mockup) collapses to stacked at < 1024px; mockup rendered below text on mobile - **Documentation grid**: 3-column desktop → sidebar-drawer at < 1024px → single-column at < 768px - **Pricing comparison**: 3-column tiers → 1-column stacked at < 768px; comparison table becomes horizontal-scroll - **Hero typography**: `{typography.hero-display}` (72px) → 56px tablet → 44px mobile-large → 36px mobile-small - **Customer logo wall**: 6-up → 3-up at tablet → 2-up at mobile - **Footer**: 5-column desktop → 2-column tablet → accordion at mobile ### Image Behavior - Hero illustrations (cloud, rocket) lazy-load with the hero band; remain crisp at all breakpoints (SVG-based) - Product mockup retains its aspect ratio across breakpoints; scales proportionally - Customer logos use SVG wordmarks; remain crisp on retina displays ## Iteration Guide 1. Focus on ONE component at a time. The system has high internal consistency. 2. Reference component names and tokens directly (`{colors.primary}`, `{component-name}-pressed`, `{rounded.full}`) — do not paraphrase. 3. Run `npx @google/design.md lint DESIGN.md` after edits to catch broken refs and contrast issues. 4. Add new variants as separate `components:` entries (`-pressed`, `-disabled`, `-focused`, `-active`). 5. Default to `{typography.body-md}` for body and `{typography.subtitle}` for emphasis. Headlines step down `hero-display → display-lg → heading-1 → heading-2 → heading-3 → heading-4 → heading-5`. 6. Keep `{colors.brand-green}` confined to accent moments. If it appears on a generic surface, ask whether it earned that role. 7. Pill-shaped buttons (`{rounded.full}`) always; squared buttons signal "third-party widget" in this language. 8. Documentation prose belongs in `{typography.body-md}` 16px with 1.50 line-height — anything denser breaks the reading experience. ## Known Gaps - Specific dark-mode token values for canvas, surface, ink, and hairline are not surfaced on these pages; the brand has not yet shipped a published dark-mode palette - Animation/transition timings are not extracted; recommend 150–200ms ease for hover/focus state transitions - Form validation success state is not explicitly captured beyond defaults — implement following standard green-border + success badge patterns - Code syntax highlighting palette inside docs is not formalized; documentation samples carry their own twoslash-style annotation system tokens (e.g. `{colors.brand-tag}`, `{colors.brand-annotate}`, `{colors.brand-warn}`) but the full highlight scheme is not enumerated
