# Convex

> Extracted from [https://www.convex.dev/](https://www.convex.dev/) on 2026-11-12 by Emblematic. Every value below was read from the rendered DOM (computed styles, `document.fonts`, and the fonts Chrome actually used to paint text), not estimated from pixels. When the YAML front matter and this prose disagree, the YAML wins. Copy values from this file exactly; don't transcribe them from memory. Don't copy logos, imagery, illustrations or marketing copy.

## Overview

Convex uses a dark canvas (#2A1B1B) with a palette led by #FAF4E9. Type is set in **GT America** (display + body), **Vcr** (mono), with 16px body text. Layout: 1344px container, top-sticky+transparent navigation, 10 sections. Built with next.js, tailwind, vercel.

## Colors

Area-weighted from painted backgrounds, text and borders on the 1440px light capture. Roles are inferred from usage (largest background, most text, interactive fills). Every hex is an exact computed value; a role marked *unverified* is a best guess that has not passed review, so its canonical token (e.g. `primary`) is left out of the front matter.

Contrast: text on background 16.52:1, muted text 9.28:1, accent 15.09:1.

Gradients in use: `linear-gradient(238deg, rgb(115, 49, 43) 2%, rgb(71, 62, 54) 69%)`; `linear-gradient(to right, rgb(255, 255, 255) 1px, rgba(0, 0, 0, 0) 1px), linear-gradient(rgb(255, 255, 255) 1px, rgba(0, 0, 0, 0) 1px)`.

The site does not change under `prefers-color-scheme: dark`.

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **GT America** (CSS: `gtAmerica`) | display, body | 300, 400, 500, 700 | 75.1% | webfont |
| **Publico** (CSS: `publico`) | other | 400, 500 | 10.0% | webfont |
| **Neue Haas Grotesk Display** (CSS: `neue-haas-grotesk-display`) | other | 900 | 6.7% | webfont |
| **Plex** (CSS: `plex`) | other | 400, 500 | 5.6% | webfont |
| **Vcr** (CSS: `vcr`) | mono | 400 | 2.6% | webfont |

Scale (px): 10, 11, 12, 14, 15, 16, 18, 20, 28, 40, 60. Effective ratio ≈ 1.303 (close to a perfect fourth). Body 16px at line-height 1.5; display 60px with tracking -0.04em. Headings are sentence case. On a 390px viewport the body is 16px and display 46px.

## Layout

Spacing follows a 4px base unit; the most used steps are 2, 4, 8, 10, 12, 16, 20, 24, 32, 40, 48, 60px. Sections open with about 64px of space before their first line of text. Content sits in a 1344px container on a 7-column grid. Text density 0.108 (text area / page area).

Section order (desktop). Kinds below the review threshold are shown as *section*:

1. **hero** (980px, bg #281D1D)
2. **section** — “All gas no breakages” (479px, bg #281D1D)
3. **logos** — “Trusted by” (376px, bg #F6EEDB)
4. **section** — “Solved.” (432px, bg #F6EEDB)
5. **section** — “Ready for agentic workloads (and everything else)” (746px, bg #191919)
6. **testimonials** (546px, bg #444435)
7. **section** — “We learned how to build and run distributed systems at exabyte scale so you don’” (513px, bg #2A1B1B)
8. **section** — “Enterprise Ready” (187px, bg #73312B)
9. **logos** — “Build a production app this afternoon” (598px, bg #573932)
10. **footer** (583px, bg #141414)

## Elevation & Depth

Style: subtle. Most used shadows:

- `rgba(0, 0, 0, 0.05) 0px 2px 11px 0px`
- `rgba(0, 0, 0, 0.06) 0px 16px 17px 0px, rgba(0, 0, 0, 0.13) 0px 91px 100px 0px, rgba(0, 0, 0, 0.04) 0px 32px 36px 0px, rgba(0, 0, 0, 0.07) 0px 8px 8px 0px, rgba(0, 0, 0, 0.1) 0px 3.2px 3.4px 0px`
- `rgba(0, 0, 0, 0.3) 0px 15px 22px 0px`

## Shapes

Dominant corner radius 4px; radii in use: 4px, 6px, 8px, 12px, 16px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#F1F1F1`, textColor `#141414`, rounded `9999px`, padding `10px 20px`, height `46px`, fontFamily `GT America`, fontSize `16px`, fontWeight `500` (e.g. “Start building”)
- **button-secondary**: backgroundColor `#F3B01C`, textColor `#141414`, rounded `9999px`, padding `6px 10px`, height `28px`, fontFamily `GT America`, fontSize `14px`, fontWeight `500` (e.g. “AI Gateway”)
- **card**: rounded `16px`, padding `16px`, backgroundColor `#292929`, shadow `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0`

## Do's and Don'ts

- Do reserve `#FAF4E9` for primary actions and highlights; it covers only 1.8% of the painted page.
- Do set body copy in GT America at 16px / 1.5.
- Do tighten large headlines (-0.04em at 60px).
- Don't introduce font weights beyond 300, 400, 500, 700, 900.
- Do keep corners at 4px for most controls, and use the larger radii only for cards and media.
- Do snap spacing to multiples of 4px.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
