MongoDB

Overview

MongoDB carries a strong dual-mode visual identity — dark deep-teal hero bands with the unmistakable bright MongoDB green ({colors.brand-green}) CTA pill paired with stark white documentation and pricing surfaces. The homepage opens with "One data platform. Unlimited AI potential." headline over a deep navy hero, the green pill sitting at the visual center as the primary CTA. Lower on the page, embedded code mockup cards (terminal-aesthetic) sit on the dark hero band, breaking out into white feature cards below. The pricing page renders a 3-tier comparison (Free / Flex / Dedicated) with a featured tier highlighted in soft mint background and bright green border. The MongoDB University page presents a course catalog grid where each tile carries a colored category tag (orange, purple, green, teal) — these are MongoDB's category-encoding accent colors and are the only place outside the brand green where saturated color appears.

The system uses Euclid Circular A as its display face. The face is contemporary geometric — confident but not overly playful — and pairs naturally with both the developer-tool aesthetic of the database product and the educational positioning of the learning surfaces. Cards use {rounded.lg} (12px) corners; buttons use {rounded.full} pills universally. The brand-teal palette ({colors.brand-teal-deep}) anchors hero bands, footer, code mockups, and the dark CTA banners.

Key Characteristics:

• Deep navy/teal hero bands ({colors.brand-teal-deep}) with bright MongoDB green ({colors.brand-green}) CTA pills
• Stark white pricing/documentation surfaces with colored category tags for course tiles (purple, orange, green, teal)
• Euclid Circular A across every UI surface
• Pill-shaped buttons ({rounded.full}) and 12px-rounded cards
• 3-tier pricing comparison (Free / Flex / Dedicated) with featured-mint highlight tier
• Code mockup cards with terminal-aesthetic dark canvas

Typography

Font Family

Euclid Circular A (primary): MongoDB's geometric sans-serif. Fallbacks: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, sans-serif. Source Code Pro (code): Monospace for code mockups. Fallbacks: 'SF Mono', Menlo, Consolas, monospace.

Hierarchy

Principles

• Tight hero leading (1.10) on 72px display
• Negative letter-spacing on display sizes (-1.5px to -0.5px)
• 600 weight reserved for buttons and small emphasis (FAQ headings, badges)
• Generous body leading (1.55) for technical documentation readability

Layout

Spacing System

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

Grid & Container

• 1280px max-width with 32px gutters
• Pricing: 3-tier card row, dense feature comparison table below
• Learn catalog: 3-up course tile grid, 4-up certification grid
• AI use cases: 2-column hero with atmospheric illustration

Whitespace Philosophy

Marketing surfaces give content generous breathing room — {spacing.hero} (120px) hero padding for deep teal bands. Pricing/learn surfaces tighten dramatically.

Elevation & Depth

Decorative Depth

• Dark teal hero bands carry atmospheric gradient depth
• Code mockup cards on hero use canvas-dark surface with terminal aesthetic
• Pale-mint pricing-feature tier uses brand-tinted shadow

Shapes

Border Radius Scale

Photography Geometry

• Hero illustrations sit on full-bleed dark backgrounds
• Course tile thumbnails use {rounded.lg} corners
• Customer logos wall: wordmarks at consistent 60–80px height

Do's and Don'ts

Do

• Use {colors.brand-green} (bright MongoDB green) for primary CTAs everywhere
• Pair dark-teal hero bands with bright green CTA pills
• Apply {rounded.full} to every button, every status badge
• Apply {rounded.lg} (12px) to cards consistently
• Use category accent colors (purple, orange, green, teal) ONLY for course tags
• Maintain Euclid Circular A across every UI surface
• Use code mockup cards with terminal-aesthetic content for product showcases

Don't

• Don't use the bright green for body text or large surfaces
• Don't introduce additional accent colors beyond the brand green and category-encoding palette
• Don't soften corners on buttons; the pill is a brand signature
• Don't replace deep teal hero bands with white hero bands
• Don't apply heavy shadows on flat documentation cards; reserve elevation for code mockups
• Don't use Source Code Pro for prose

Responsive Behavior

Breakpoints

Touch Targets

• Pill buttons render at 40–44px effective height
• Form inputs render at 44px height
• Search pill (large) renders at 56px
• Pill tabs ~32px → 44px on mobile

Collapsing Strategy

• Promo banner stays full-width; truncates at < 480px
• Top nav below 1024px collapses to hamburger
• Hero band: code mockup card moves below text on mobile
• Pricing tiers: 3-column → 2-column tablet → 1-column mobile
• Course catalog: 3-up → 2-up tablet → 1-up mobile
• Hero typography: 72px → 56px → 48px → 36px
• Footer: 6-column desktop → 3-column tablet → accordion mobile

Image Behavior

• Atmospheric AI imagery uses 16:9 ratio with full-bleed scaling
• Code mockup card content remains readable across breakpoints
• Customer logo wall: wordmarks at consistent 60–80px height

Iteration Guide

1. Focus on ONE component at a time
2. Reference component names and tokens directly
3. Run npx @google/design.md lint DESIGN.md after edits
4. Add new variants as separate components: entries
5. Default to {typography.body-md} for body
6. Keep {colors.brand-green} as the primary CTA across all surfaces
7. Pill-shaped buttons ({rounded.full}) always
8. Dark-teal hero bands frame primary CTAs

Known Gaps

• Specific dark-mode token values for canvas/surface beyond hero bands not surfaced
• Animation/transition timings not extracted; recommend 150–200ms ease
• Form validation success state not explicitly captured
• Course-tile category color mappings are observation-based
