# Quantamagazine

> Extracted from [https://www.quantamagazine.org/](https://www.quantamagazine.org/) 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

Quantamagazine uses a light canvas (#FFFFFF) with a palette led by #FF8600. Type is set in **Pangram**, **Noe Display** (display), with 13px body text. Layout: 1160px container, none-detected navigation, 6 sections. Built with wordpress, tailwind, jquery, 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 | 66.7% | `--theme-background` |
| `on-surface` | `#1A1A1A` | 0.218 0 0 | text | 22.3% | `--theme-text` |
| `surface` | `#EFEFEF` | 0.952 0 0 | surface | 5.6% | — |
| `on-surface-variant` | `#6B6B6B` | 0.528 0 0 | muted | 2.8% | — |
| `primary` | `#FF8600` | 0.741 0.182 55.6 | accent | 0.22% | `--theme-accent` |
| `color-6` | `#767676` | 0.566 0 0 | other | 1.3% | — |
| `color-7` | `#00000012` (on bg `#EDEDED`) | 0 0 0 | other | 0.49% | — |
| `color-8` | `#000000B3` (on bg `#4D4D4D`) | 0 0 0 | other | 0.32% | — |
| `color-9` | `#1A1A1A0D` (on bg `#F4F4F4`) | 0.218 0 0 | other | 0.28% | — |

Contrast: text on background 17.4:1, muted text 5.33:1, accent 2.42:1.

Gradients in use: `linear-gradient(rgb(26, 26, 26), rgba(26, 26, 26, 0.05) 90%, rgba(26, 26, 26, 0))`; `radial-gradient(rgba(0, 0, 0, 0.075) 0px, rgba(0, 0, 0, 0) 65%)`.

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

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Pangram** | body | 400, 500, 600, 700, 800 | 50.5% | webfont |
| **Noe Display** | display | 700 | 40.5% | webfont |
| **Merriweather** | other | 400, 500, 700 | 9.0% | webfont |

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

Scale (px): 9, 10, 11.5, 12, 13, 15, 16, 18, 22, 35, 40, 45. Effective ratio ≈ 1.194 (close to a minor third). Body 13px at line-height 1.875; display 45px with tracking 0em. Headings are title case. On a 390px viewport the body is 13px and display 35.04px.

## Layout

Spacing has no reliable single base unit; the most used steps are 2.5, 3, 3.5, 4, 5, 6, 7.5, 8, 10, 12, 16, 20, 22.5, 32px. Sections open with about 80px of space before their first line of text. Content sits in a 1160px container. Text density 0.076 (text area / page area).

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

1. **nav** (80px)
2. **hero** — “How a Metabolic Spark Could Have Jump-Started Life” (2025px, bg #FFFFFF)
3. **section** — “Is There Anything Left in the Dream of Cold Fusion?” (1913px, bg #FFFFFF)
4. **section** — “Featured Videos” (1408px, bg #1A1A1A)
5. **section** — “About Quanta Magazine” (490px, bg #FFFFFF)
6. **footer** (537px, bg #EFEFEF)

## Elevation & Depth

Style: subtle. Most used shadows:

- `rgba(0, 0, 0, 0.2) 0px 2px 5px 0px`
- `rgba(0, 0, 0, 0.4) 0px -3px 112px -40px`

## Shapes

Dominant corner radius is a full pill; radii in use: pill. Borders: regular (2px).

## Components

- **button-secondary**: textColor `#1A1A1A`, rounded `0px`, padding `13px 35px`, height `57.1px`, fontFamily `Pangram`, fontSize `16px`, fontWeight `700`, border `2px solid #FF8600` (e.g. “Read the Latest →”)
- **input**: rounded `0px`, height `60px`, padding `18px 21.6px`

## Do's and Don'ts

- Do reserve `#FF8600` for primary actions and highlights; it covers only 0.22% of the painted page.
- Do set body copy in Pangram at 13px / 1.875.
- Do use Noe Display only for display sizes, not for body text.
- Don't introduce font weights beyond 400, 500, 600, 700, 800.
- Do keep corners at pill for most controls.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
