microsoft.ai — Design System
1. Visual Theme & Atmosphere
Microsoft AI’s site embodies corporate kinetics: a warm-white canvas with a single bold red primary, rendered at cinematic viewport widths up to 1728px. The aesthetic is deliberately restrained — almost editorial — using fluid viewport-unit scaling (--unit-fx, --unit-fy) to create motion that feels purpose-built rather than decorative. The 11px vertical rhythm unit (--unit-vr) telegraphs a grid-literate engineering culture behind the design. Red is not playful here; it is authoritative.
2. Color Palette & Roles
| Role | Value | Usage |
|---|---|---|
| Brand / Accent | red (#ff0000) |
Primary CTAs, hover states, brand marks |
| Warm White Background | rgb(255, 248, 243) |
Page canvas |
| Pure White Surface | #ffffff |
Cards, modals, elevated panels |
| Black | #000000 |
Body text, borders |
The palette is intentionally minimal: one accent, two neutrals, and white. Absence of mid-grays keeps the site feeling airy and premium.
3. Typography Rules
- Primary typeface: Custom/proprietary sans-serif; fallback chain suggests a brand-licensed typeface
- Vertical rhythm:
--vertical-rhythm: 11px— all spacing derives from this unit - Scale: Fluid via
--unit-vwand--unit-vhfix— type sizes scale proportionally with viewport - No decorative transforms: All text is set naturally; uppercase labels absent from tokens
| Level | Approach |
|---|---|
| Hero | Viewport-unit scaled, large display weight |
| Body | Derived from 11px rhythm unit |
| Caption | Small multiples of --unit-vr |
4. Component Stylings
- Buttons: Red fill with white text — single accent color makes every CTA immediately legible
- Navigation: Transparent/sticky; inherits warm-white page background
- Cards: White (#ffffff) elevated from the warm-white page via luminance contrast rather than shadows
- Easing:
--alias-easeOut: cubic-bezier(0.43, 0.195, 0.02, 1)— fast-in, slow-out; decisive and intentional
5. Layout Principles
- Max canvas:
--max-width: 1728px— designed for large displays; content breathes at wide viewports - Reference width: 1728px with fluid
--unit-fxscaling for sub-pixel precision - Breakpoints: 340 → 600 → 768 → 1024 → 1728px
- Whitespace: Generous; rhythm-unit spacing prevents cramping even at high content density
6. Depth & Elevation
- Surface elevation achieved through color temperature contrast (warm page background vs. pure-white cards)
- Soft warm shadow:
rgba(93, 82, 75, 0.3) 0px 4px 80px 0px— wide-spread, barely-there lift - No aggressive drop shadows; depth is implied, not stated
7. Do’s and Don’ts
Do:
- Use red exclusively for calls-to-action and brand anchors
- Respect the 11px vertical rhythm in all spacing decisions
- Let layouts breathe at 1728px — do not compress to 1280px max
- Use the custom easing curve for interactive transitions
Don’t:
- Introduce secondary accent colors that compete with red
- Use cold-gray backgrounds — the warmth of
rgb(255, 248, 243)is intentional - Break the fluid type scaling with fixed pixel values at wide screens
8. Responsive Behavior
- Fluid scaling via CSS
calc()and viewport units — not purely breakpoint-driven - Five breakpoints: 340, 600, 768, 1024, 1728
- Mobile: single-column, rhythm preserved
- Desktop: full viewport-width hero sections up to 1728px
9. Agent Prompt Guide
“Design in the style of Microsoft AI: warm off-white background (
rgb(255, 248, 243)), pure red single accent, large-canvas layout up to 1728px wide, 11px vertical rhythm, fluid viewport-unit scaling, decisive cubic-bezier easing. Minimal palette — no competing accent colors.”
