# DESIGN.md: Rivian-style design system

Measured from https://rivian.com/ on 2026-10-15 by PikSpec (https://www.pikspec.com). An independent measurement of the rendered page, not Rivian's official design system, and not affiliated with Rivian.

Use it to build your own product in this design language: put this file in your project root and tell your AI tool (Claude Code, Cursor, Codex, Lovable, v0) to follow DESIGN.md. Never use the original's name, logo, copy or images; licensed fonts are replaced with the closest free Google Fonts.

HOW IT SHOULD LOOK
Build it in the design language of rivian.com, measured from the live site: it should feel designed by the same team as rivian.com — the same temperament, colour, type and density — for a different product. Never use rivian.com's name, logo, words or images.

Stack: use the one your project already has. Starting fresh: React + Vite + TypeScript + Tailwind CSS v4, with no UI kit (no shadcn/ui, MUI or Chakra) — their defaults would override this system. In a chat that shows one file (an artifact or canvas), build one HTML file instead, with the tokens below in its <style> block.
Use every value exactly as written. Do not round, rename, approximate or substitute a colour, size, radius, shadow or easing (fonts: see section 1). Anything not listed here does not exist in this system.

THE WEBSITE THIS SYSTEM COMES FROM
- Reference page: https://rivian.com/ — "rivian.com" (home page).
- Page frame: a top navigation bar and a footer.
- Content is grouped in cards (20 on the page). Keep cards for grouped content only, not for every section.
- It uses 120 images including 27 videos, 28 of them large. Large, real product imagery is part of the look — leave clearly labelled image slots at those sizes rather than stock photos or abstract 3D shapes.
- Interaction: 49 buttons and 2 form fields on one page.
- The page runs about 18 screens long at 1440px wide.
- Density is low: few elements per screen, generous space around each one.

HOW IT LOOKS (WHAT MAKES IT LOOK LIKE ITSELF, BEYOND THE VALUES)
- Almost entirely neutral: 99% of the page is painted in #F2F2F2 and #9FA1B8.
- #8BA8BD is an accent: 0.6% of the page, as small fills such as buttons and badges. Keep it to small areas.
- #FFAC00 is an accent: 0.2% of the page, as small fills such as buttons and badges. Keep it to small areas.
- The largest type (360px Liga) is medium weight, not bold (500), tracked to -0.022em, in capitals.
- Open: text covers 8% of the page.
- Share of the painted page: #F2F2F2 54.1% (dominant, backgrounds); #9FA1B8 14.9% (supporting, backgrounds); #FFFFFF 10% (supporting, backgrounds and text); #000000 9.9% (supporting, backgrounds and text); #212121 6.3% (supporting, backgrounds); #ECECEC 3.4% (detail, backgrounds); #8BA8BD 0.6% (accent, backgrounds); #FFAC00 0.2% (accent, backgrounds). Keep accents at these proportions; do not promote them to fills.
- Small marks: 14 small decorative marks (dots, crosses or ticks under 16px) in #CBCBCB and #151515, placed at corners and edges.
- Large images: Photographs, video or raster artwork cover about 122% of the page.
- Type as set (size, weight and tracking measured together; use these pairs): 360px weight 500 tracking -0.022em uppercase; 72px weight 600 tracking -0.025em; 56px weight 600 tracking -0.045em; 44px weight 600 tracking -0.02em; 36px weight 600 tracking -0.02em; 32px weight 500 tracking -0.021em.

1. DESIGN TOKENS — PASTE INTO YOUR GLOBAL CSS
Allowed colours, with how the original uses each. Use no other colour, including in hover states:
- #F2F2F2 — 54.1% · backgrounds (var(--color-surface))
- #9FA1B8 — 14.9% · backgrounds (var(--color-9fa1b8))
- #FFFFFF — 10% · backgrounds, text (var(--color-background))
- #000000 — 9.9% · backgrounds, text (var(--color-on-action))
- #212121 — 6.3% · backgrounds (var(--color-212121))
- #ECECEC — 3.4% · backgrounds (var(--color-ececec))
- #8BA8BD — 0.6% · backgrounds (var(--color-8ba8bd))
- #FFAC00 — 0.2% · backgrounds (var(--color-action))
- #629B5C — 0.1% · backgrounds
- #E84826 — 0.1% · backgrounds
- #CBCBCB — small marks (var(--color-border))
- #151515 — small marks (var(--color-text))
- #636363 — Text muted (var(--color-text-muted))
- #E84A26 — Negative (var(--color-negative))
Fonts — put these first in your global CSS (one import per font, so one that fails cannot stop the others):
```css
@import url("https://fonts.googleapis.com/css2?family=Figtree:wght@400;500;600;700&display=swap");
@import url("https://fonts.googleapis.com/css2?family=Inter+Tight:wght@400;500&display=swap");
```
Font: rivian.com uses Adventure (body), Sohne (interface) and Liga (display) — its own licensed faces, not available to download. This kit uses Figtree for body and display and Inter Tight for interface, the closest free matches, already in the tokens. If you own the original, add it with @font-face and it is used first; to use another font, change the --font-* variables.
Keep every size, weight, line height and tracking exactly as listed whichever font renders.

Tailwind CSS v4 (the default for new projects): put this after `@import "tailwindcss";`. It removes Tailwind's own palette, so only these colours exist as utilities:

Tailwind CSS v3 only: extend the theme with these instead, and use no other palette:
```js
// tailwind.config — theme.extend
{
  colors: { "background": "var(--color-background)", "surface": "var(--color-surface)", "text": "var(--color-text)", "text-muted": "var(--color-text-muted)", "border": "var(--color-border)", "action": "var(--color-action)", "on-action": "var(--color-on-action)", "negative": "var(--color-negative)" },
  fontFamily: { "body": ["var(--font-body)"], "interface": ["var(--font-interface)"], "display": ["var(--font-display)"] },
  borderRadius: { "sm": "var(--radius-sm)", "md": "var(--radius-md)", "lg": "var(--radius-lg)", "2xl": "var(--radius-2xl)", "3xl": "var(--radius-3xl)", "full": "var(--radius-full)" },
  boxShadow: { "e1": "var(--elevation-1)", "e2": "var(--elevation-2)", "e3": "var(--elevation-3)", "e4": "var(--elevation-4)", "e5": "var(--elevation-5)" },
}
```

Where a component lists recorded states, write those states using only the colours above; the capture saw that the state exists, not its values. Never invent a state colour.

4. PAGE COMPOSITION
- Light interface on #FFFFFF. Keep that ground; do not add a dark mode.
- The opening screen carries a large image or video behind or across the heading. Leave a [content: hero image or video] slot there, at least half the screen wide; the opening is not text alone.
- Sections change ground between #ECECEC, Surface (#F2F2F2), #9FA1B8 and On action (#000000); use only those.
- #FFAC00 is the action colour. Fill the primary action with it and little else — at most one #FFAC00-filled element per screen; other accents keep to the uses listed above.
- Type: Figtree (standing in for Adventure) for body; Inter Tight (standing in for Sohne) for interface; Figtree (standing in for Liga) for display. Hierarchy comes from size and weight, not colour or decoration.
- Everything sits on a 4px grid.
- Corner radii are 4px, 8px, 12px, 20px, 36px, fully round (pill) — nothing else.
- Body text uses Adventure at around 16px, weights 400, 500, 600, 700.
- Headings use Liga; the largest heading is 360px.
- Primary buttons are #FFAC00, 40px radius, weight 500.
- Cards use 20px corners with a soft shadow.
- Corner radii in use: 40px, 99px, 20px, 9999px (pill), 12px.

HOW THE ORIGINAL PACES ITS PAGE (BORROW THE RHYTHM — THE OPENING, THE COLOURED BANDS, THE CARD GRIDS — NOT THE LIST; BUILD THE SECTIONS YOUR PRODUCT NEEDS)
1. Hero — 765px tall, 4 equal columns, left-aligned 56px heading (weight 600) set mid-band, image behind the content, on #ECECEC.
2. Hero — about 900px tall (the original scroll-animates this band over 6086px; build it as one screen), 3 equal columns, centred 360px heading (weight 500), image behind the content.
3. Cards — 906px tall, 3 equal columns, centred 72px heading (weight 600), image on the left.
4. Statement — 246px tall, centred 72px heading (weight 600), image centred.
5. Text — 760px tall, a strip of 10 small items (logos, links or icons), left-aligned 56px heading (weight 600) set low in the band, image on the right.
6. Full-bleed image — 900px tall, image behind the content.
7. Cards — 924px tall, 3 equal columns, 16px gap, left-aligned 72px heading (weight 600), image on the left.
8. Statement — 616px tall, centred 72px heading (weight 600) set mid-band.
9. Full-bleed image — 810px tall, image behind the content.
10. Split — 982px tall, 2 equal columns, 125px gap, centred 72px heading (weight 600).
11. Full-bleed image — 960px tall, centred 72px heading (weight 600), image behind the content.
12. Text — 880px tall, left-aligned 14px heading (weight 400), on #212121.
13. Footer — 500px tall, split 3 / 2 / 7, left-aligned 32px heading (weight 400), on #212121.
- Content runs 1264px wide with 108px side margins at 1440px; there is no narrower centred container.
- A 56px header scrolls away.
- The hero is 765px (0.9 screens): 4 equal columns, left-aligned 56px heading (weight 600) set mid-band, image behind the content, on #ECECEC.
- Column splits on a 12-column grid: thirds (3×), quarters, halves, 3/2/7; gaps of 16px.
- Headings mix left (5) and centred (6) alignment.
- Sections change background 2 times, between #ECECEC, #212121: colour comes in full-width bands, not in boxes.
- A typical section is about 900px tall.

COPY SHAPE (MATCH THE LENGTH AND CASE; WRITE YOUR OWN WORDS)
- The main heading is 3 words long.
- Section headings are short: typically 3 words.
- Headings are in sentence case (only the first word capitalised).
- The page describes itself in about 21 words; keep your intro paragraph to about that length.

5. MOTION
Interactive elements change colour, background, border and opacity with the measured timing. Animate nothing else.
```css
a, button, [role="button"], input { transition: color var(--duration-1) var(--ease-1), background-color var(--duration-1) var(--ease-1), border-color var(--duration-1) var(--ease-1), opacity var(--duration-1) var(--ease-1); }
@media (prefers-reduced-motion: reduce) {
  *, *::before, *::after { animation-duration: 0.01ms !important; animation-iteration-count: 1 !important; transition-duration: 0.01ms !important; scroll-behavior: auto !important; }
}

No scroll-triggered fade-ins, parallax, typewriter text or bouncing elements.

6. RESPONSIVE
- The design was measured at 1440px wide. Lay it out for that width first, then let it reflow down to 360px.
- Content sits in a column at most 880px wide, centred, with var(--space-4) (16px) side padding on small screens.
- The largest heading scales fluidly: font-size: clamp(72px, 25vw, 360px). Every other size stays fixed.
- Break on composition, not device names: a row of columns drops a column when any column would be narrower than 240px; side-by-side splits stack when either side would be narrower than 320px.
- Spacing steps never change between sizes; use smaller steps from the same list where space is tight.
- On touch screens, every link and button has a hit area of at least 44 × 44px without changing its drawn size.

7. ACCESSIBILITY
- Text pairs that pass for body copy: Text on Background (18.3:1), Text muted on Background (6:1), Text on Surface (16.3:1), Text muted on Surface (5.4:1) and On action on Action (11.2:1).
- Only for text 24px and up, or 18.66px bold: Negative on Background (3.9:1) and Negative on Surface (3.4:1).
- Use no other text-on-background pairing.
- One h1 per page, headings in order, landmarks (header, nav, main, footer), real buttons and links, a label on every field, alt text on every image, an aria-label on icon-only buttons.
- Every interactive element shows the :focus-visible outline above.

8. DO NOT (THESE ARE WHAT MAKE AI-BUILT SITES LOOK GENERIC)
- No gradients: not in backgrounds, text, buttons or borders. (No gradient was measured.)
- Only these colours: #F2F2F2, #9FA1B8, #FFFFFF, #000000, #212121, #ECECEC, #8BA8BD, #FFAC00, #629B5C, #E84826, #CBCBCB, #151515, #636363, #E84A26. No new tints, no Tailwind defaults (slate, indigo, violet). (They are every colour that covers a measurable part of the page, and the colours its lines and drawings use.)
- #8BA8BD only as small fills (buttons, badges) — never a section background or a large panel. (It covers 0.6% of the page.)
- #FFAC00 only as small fills (buttons, badges) — never a section background or a large panel. (It covers 0.2% of the page.)
- Only the fonts in the tokens: Figtree for body; Inter Tight for interface; Figtree for display. No other typeface, and no Inter, Roboto or system UI font unless it is one of these. (The page is set in Adventure and Liga and Sohne; the tokens carry what stands in for them.)
- Headings and large text never heavier than weight 600. Do not make headlines bold to add emphasis. (Every size from 24px up is set at weight 600 or lighter.)
- Large headlines tracked tight (letter-spacing -0.022em), not at the browser default. (The 360px headline is set at -0.022em.)
- No icon above every feature, no emoji, no decorative blobs, sparkles or glows. (None of these is part of the captured design; they are a coding model's defaults.)
- The hero is left-aligned. Do not centre it. (The captured hero sets its heading on the left.)
- Build the sections your product needs, not the original's list. Give each one this system's look: its kinds of section (hero, cards, statement, text, image, split, footer), its colours, type, shapes and spacing. (The style carries to any kind of site; the original's page was for a different product.)
- No glassmorphism, backdrop blur, glowing orbs, noise blobs or neon outlines.
- No row of three identical feature cards as the default section. Vary the layout from section to section: a split, a list, a single large statement, a table.
- No centred-everything hero with a pill badge, a gradient headline and two buttons. Lead with the most specific thing about the product.
- No filler copy: no "Unlock your potential", "Revolutionize", "Seamless", "Elevate", "Supercharge", "Next-gen" or lorem ipsum. Write plain, specific sentences a real company would publish.
- No made-up statistics, testimonials or customer logos. Leave a clearly marked [content: …] slot instead.
- No radius larger than the largest one listed.
- No shadows other than the levels listed.
- Do not use rivian.com's name, logo, copy or images. This is its design system, not its content.

BEFORE YOU FINISH
- Search your code for every colour, font size, spacing value, radius, shadow and easing, and replace anything that is not a variable above.
- Check that no [content: …] slot has been filled with invented facts.
- Search your CSS for gradient(. There should be none.
- Every colour value in your CSS is one of the allowed colours. Nothing else, including in hover states.
- #8BA8BD covers about 0.6% of the page or less, as on the original.
- #FFAC00 covers about 0.2% of the page or less, as on the original.
- No text 24px or larger has a font-weight above 600.
- The largest headline uses letter-spacing -0.022em.
- Every section, including ones the original does not have, uses only this system's colours, type, shapes and spacing.
- There is no placeholder copy (lorem ipsum, "Feature one", "Your headline here"). Every word is real.
- Take a screenshot at 1440px and put it beside the original. List every difference in colour, weight, spacing, alignment and imagery, and fix each before finishing. Then check 390px wide: nothing scrolls sideways and no heading runs off the screen.
