# DESIGN.md: Zoom-style design system

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

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 zoom.com, measured from the live site: it should feel designed by the same team as zoom.com — the same temperament, colour, type and density — for a different product. Never use zoom.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://www.zoom.com/ — "www.zoom.com" (home page).
- Page frame: a top navigation bar, a persistent side panel beside the content and a footer. This is a tool- or docs-style layout, not a marketing page of stacked full-width bands.
- Content is grouped in cards (18 on the page, up to 5 side by side). Keep cards for grouped content only, not for every section.
- It uses 66 images including 1 video, 27 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: 38 buttons on one page.
- The page runs about 8 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)
- Mostly neutral: 85% of the page is #FFFFFF and #E0E0E6 and other neutrals; #00053D (14.3%) fills whole sections.
- #0B5CFF is an accent: 0.7% of the page, as small fills such as buttons and badges. Keep it to small areas.
- #1722F6 is an accent: 0.1% of the page, used for text only. Don't fill large areas with it.
- The largest type (54px Newsreader) is medium weight, not bold (500).
- Open: text covers 8% of the page. Sections sit about 60px apart.
- Share of the painted page: #FFFFFF 76.5% (dominant, backgrounds); #00053D 14.3% (supporting, backgrounds and text); #E0E0E6 6.2% (supporting, backgrounds); #E6F0FF 1.1% (detail, backgrounds); #0B5CFF 0.7% (accent, backgrounds and text); #00031F 0.4% (detail, text); #F3F8FF 0.2% (detail, backgrounds); #696B6E 0.2% (detail, text). Keep accents at these proportions; do not promote them to fills.
- Hairline dividers: 1px lines in #0B5CFF separate sections and rows (23 of them).
- Small marks: 11 small decorative marks (dots, crosses or ticks under 16px) in #D1DEF2, placed at corners and edges.
- Large images: Photographs, video or raster artwork cover about 28% of the page.
- Type as set (size, weight and tracking measured together; use these pairs): 54px weight 500; 46px weight 500; 32px weight 500; 26px weight 600; 22px weight 450; 20px weight 500 tracking -0.02em.

1. DESIGN TOKENS — PASTE INTO YOUR GLOBAL CSS
Allowed colours, with how the original uses each. Use no other colour, including in hover states:
- #FFFFFF — 76.5% · backgrounds (var(--color-background))
- #00053D — 14.3% · backgrounds, text (var(--color-text))
- #E0E0E6 — 6.2% · backgrounds (var(--color-e0e0e6))
- #E6F0FF — 1.1% · backgrounds (var(--color-e6f0ff))
- #0B5CFF — 0.7% · backgrounds, text (var(--color-link))
- #00031F — 0.4% · text
- #F3F8FF — 0.2% · backgrounds
- #696B6E — 0.2% · text (var(--color-text-muted))
- #181819 — 0.1% · text
- #1722F6 — 0.1% · text
- #D1DEF2 — hairlines and grid lines (var(--color-border))
- #D3D3D3 — Surface (var(--color-surface))
- #F5642D — Warning (var(--color-warning))
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=Inter:wght@400;500;600;700;900&display=swap");
@import url("https://fonts.googleapis.com/css2?family=Newsreader:wght@400;500;600&display=swap");
```
Inter and Newsreader are on Google Fonts and loaded from there.
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)", "link": "var(--color-link)", "warning": "var(--color-warning)" },
  fontFamily: { "body": ["var(--font-body)"], "display": ["var(--font-display)"] },
  borderRadius: { "xs": "var(--radius-xs)", "sm": "var(--radius-sm)", "md": "var(--radius-md)", "lg": "var(--radius-lg)", "xl": "var(--radius-xl)", "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)", "e6": "var(--elevation-6)", "e7": "var(--elevation-7)" },
}
```

2. BASE STYLES
```css
html { background: var(--color-background); }
body { margin: 0; font-family: var(--font-body); font-size: var(--type-body-large); line-height: var(--type-body-large-leading); color: var(--color-text); -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; }
h1, h2, h3 { font-family: var(--font-display); margin: 0; }
a { color: var(--color-link); }
:focus-visible { outline: 2px solid var(--color-action); outline-offset: 2px; }
```

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 on the left. 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 Background (#FFFFFF) and Text (#00053D); use only those.
- #00053D is the action colour. Fill the primary action with it and little else — at most one #00053D-filled element per screen; other accents keep to the uses listed above.
- Type: Inter for body; Newsreader for display. Hierarchy comes from size and weight, not colour or decoration.
- Corner radii are 1px, 2px, 3px, 4px, 8px, 10px, 12px, fully round (pill) — nothing else.
- Body text uses Inter at around 16px, weights 400, 450, 500, 600, 700, 900.
- Headings use Newsreader; the largest heading is 54px.
- Primary buttons are #00053D, 12px radius, weight 600.
- Cards use 20px 20px 0px 0px corners.
- Corner radii in use: 8px, 12px, 20px, 2px, 1px.

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 — 1032px tall, a strip of 12 small items (logos, links or icons), centred 54px heading (weight 500), image on the left.
2. Text — 1004px tall, left-aligned 46px heading (weight 400), image centred, on #FFFFFF.
3. Cards — 637px tall, 3 equal columns, 40px gap, centred 16px heading (weight 600) set low in the band, image centred, on #FFFFFF.
4. Split — 839px tall, 2 equal columns, 40px gap, centred 46px heading (weight 500), image on the right, on #FFFFFF.
5. Split — 254px tall, 2 equal columns, centred 20px heading (weight 600), image on the right.
6. Cards — 1069px tall, split 9 / 1 / 1 / 1, 16px gap, centred 46px heading (weight 500) set mid-band, image on the left.
7. Cards — 705px tall, 3 equal columns, 20px gap, centred 46px heading (weight 500), image on the left, on #FFFFFF.
8. Statement — 336px tall, centred 46px heading (weight 500).
9. Footer — 869px tall, split 4 / 2 / 2 / 2 / 2, 37px gap, left-aligned 22px heading (weight 450) set low in the band, on #00053D.
- Content sits in a 1154px container, 163px from the edge at 1440px wide.
- A 78px header stays fixed at the top, transparent over the first section.
- The hero is 1032px (1.1 screens): a strip of 12 small items (logos, links or icons), centred 54px heading (weight 500), image on the left.
- Column splits on a 12-column grid: thirds (2×), halves (2×), 9/1/1/1, 4/2/2/2/2; gaps of 37px.
- Headings are centred (7 of 9 sections).
- Sections change background 5 times, between #FFFFFF, #00053D: colour comes in full-width bands, not in boxes.
- A typical section is about 705px tall.

COPY SHAPE (MATCH THE LENGTH AND CASE; WRITE YOUR OWN WORDS)
- The main heading is 7 words long.
- Section headings are medium length: typically 6 words.
- Heading case varies.
- The page describes itself in about 20 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 1154px wide, centred, with var(--space-16) (16px) side padding on small screens.
- The largest heading scales fluidly: font-size: clamp(32px, 3.8vw, 54px). 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 (19.3:1), Text muted on Background (5.3:1), Action on Background (19.3:1), Link on Background (5.3:1), Text on Surface (12.9:1), Action on Surface (12.9:1) and On action on Action (19.3:1).
- Only for text 24px and up, or 18.66px bold: Text muted on Surface (3.6:1) and Link on Surface (3.5:1).
- 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: #FFFFFF, #00053D, #E0E0E6, #E6F0FF, #0B5CFF, #00031F, #F3F8FF, #696B6E, #181819, #1722F6, #D1DEF2, #D3D3D3, #F5642D. 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.)
- #0B5CFF only as small fills (buttons, badges) — never a section background or a large panel. (It covers 0.7% of the page.)
- #1722F6 only for text — never as a section background or a large panel. (It covers 0.1% of the page.)
- Only the fonts in the tokens: Inter for body; Newsreader for display. No other typeface, and no Inter, Roboto or system UI font unless it is one of these. (The page is set in Inter and Newsreader; 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.)
- No all-caps eyebrow labels above headings. (No uppercase text was measured.)
- 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.)
- Build the sections your product needs, not the original's list. Give each one this system's look: its kinds of section (hero, text, cards, split, statement, 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 zoom.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.
- #0B5CFF covers about 0.7% of the page or less, as on the original.
- #1722F6 covers about 0.1% of the page or less, as on the original.
- No text 24px or larger has a font-weight above 600.
- Every section, including ones the original does not have, uses only this system's colours, type, shapes and spacing.
- Content sits in a 1154px container with 163px side margins at 1440px.
- 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.
