# Cloudflare

> Extracted from [https://www.cloudflare.com/](https://www.cloudflare.com/) 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

Cloudflare uses a light canvas (#FFFFFF) with a palette led by #FF5E1F. Type is set in **STK Bureau Sans** (display + body), **Apercu Mono Pro** (mono), with 16px body text. Layout: 1200px container, top-fixed+transparent navigation, 1 sections. Built with astro, tailwind, shadcn/ui, google-tag-manager, cloudflare.

## 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.

| Token | Hex | OKLCH | Role | Share of paint | CSS variable |
|---|---|---|---|---|---|
| `background` | `#FFFFFF` | 1 0 0 | bg | 78.0% | `--color-background` |
| `primary` | `#FF5E1F` | 0.687 0.208 38.8 | accent | 7.9% | `--color-kumo-brand` |
| `on-surface` | `#262626` | 0.269 0 0 | text | 2.3% | `--color-foreground-100` |
| `on-surface-variant` | `#262626B3` (on bg `#676767`) | 0.269 0 23.6 | muted | 1.1% | — |
| `outline` | `#F0F0F0` | 0.955 0 0 | border | 0.31% | `--color-border-100` |
| `color-6` | `#FF5E1F4D` (on bg `#FFCFBC`) | 0.687 0.208 38.8 | other | 7.1% | — |
| `color-7` | `#FF5E1F1A` (on bg `#FFEFE9`) | 0.687 0.208 38.8 | other | 0.70% | — |
| `text-tertiary` | `#727272` | 0.552 0 0 | other | 0.82% | `--color-text-tertiary` |
| `black` | `#000000` | 0 0 0 | other | 0.39% | `--color-black` |
| `color-10` | `#FFFFFFCC` (on bg `#FFFFFF`) | 1 0 39 | other | 0.29% | — |
| `color-11` | `#FFFFFF0D` (on bg `#FFFFFF`) | 1 0 39 | other | 0.23% | — |
| `accent-200` | `#FF7038` | 0.711 0.188 40.4 | other | 0.04% | `--color-accent-200` |

Sparse chromatic highlights (not accents): `#BF4C14` (`--color-accent-muted`), `#ED1641`, `#FF7038` (`--color-accent-200`), `#D61F26`.

Declared brand/accent tokens: `--color-node-accent` = `#FF5315`.

Contrast: text on background 15.13:1, muted text 5.65:1, accent 3.06:1.

Gradients in use: `linear-gradient(rgb(240, 240, 240) 50%, rgba(0, 0, 0, 0) 50%)`; `linear-gradient(to left in oklab, rgb(253, 253, 252) 0%, rgba(0, 0, 0, 0) 100%)`.

The site responds to `prefers-color-scheme: dark`; the `-dark` tokens hold the dark-mode roles.

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **STK Bureau Sans** | display, body | 400, 500 | 99.4% | webfont |
| **Apercu Mono Pro** | mono | 400 | 0.50% | webfont |

Declared in `@font-face` but not used to paint text on this page: FT Kunst Grotesk. Don't treat these as the page's fonts.

Scale (px): 12, 13, 14, 16, 18, 19, 32, 48, 56. Effective ratio ≈ 1.285 (close to a major third). Body 16px at line-height 1.2; display 56px with tracking -0.025em. Headings are sentence case. On a 390px viewport the body is 16px and display 40px.

## Layout

Spacing follows a 4px base unit; the most used steps are 2, 4, 6, 8, 10, 12, 14, 16, 24, 32, 40, 48px. Content sits in a 1200px container on a 3-column grid. Text density 0.119 (text area / page area).

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

1. **hero** (7012px, bg #FFFFFF)

## Elevation & Depth

Style: layered. Most used shadows:

- `rgba(255, 255, 255, 0.2) 1px 6px 6px 0px inset, rgba(0, 0, 0, 0.02) 0px 4px 12px 0px, rgba(0, 0, 0, 0.03) 0px 2px 12px 0px`
- `rgba(0, 0, 0, 0.1) 0px 1px 3px 0px, rgba(0, 0, 0, 0.1) 0px 1px 2px -1px`
- `rgba(255, 80, 10, 0.06) 0px 4px 60px 0px, rgba(0, 0, 0, 0.03) 0px 2px 12px 0px`

## Shapes

Dominant corner radius 3px; radii in use: 3px, 4px, 6px, 8px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#FFFFFF`, textColor `#1F1F1F`, rounded `9999px`, padding `12px 24px`, height `50px`, fontFamily `STK Bureau Sans`, fontSize `16px`, fontWeight `500`, border `1px solid #FFFFFF` (e.g. “Start building for free”)
- **button-secondary**: textColor `#FFFFFF`, rounded `9999px`, padding `6px 12px`, height `38px`, fontFamily `STK Bureau Sans`, fontSize `16px`, fontWeight `500`, border `1px solid #FFFFFF66` (e.g. “Contact sales”)
- **card**: rounded `8px`, padding `0px`, backgroundColor `#FDFDFC`

## Do's and Don'ts

- Do reserve `#FF5E1F` for primary actions and highlights; it covers only 7.9% of the painted page.
- Do set body copy in STK Bureau Sans at 16px / 1.2.
- Do tighten large headlines (-0.025em at 56px).
- Don't introduce font weights beyond 400, 500.
- Do keep corners at 3px 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.
