# Vuejs

> Extracted from [https://vuejs.org/](https://vuejs.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

Vuejs uses a light canvas (#FFFFFF) with a palette led by #42B883. Type is set in **Inter** (display + body), **system-ui** (mono), with 15px body text. Layout: 960px container, top-fixed+transparent navigation, 5 sections. Built with vue, storyblok, netlify.

## 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 | 93.7% | `--vt-c-bg` |
| `on-surface` | `#213547` | 0.321 0.041 246.7 | text | 3.6% | `--vt-c-text-1` |
| `on-surface-variant` | `#3C3C3CB3` (on bg `#777777`) | 0.356 0 0 | muted | 1.7% | `--vt-c-text-2` |
| `primary` | `#42B883` | 0.703 0.132 160.4 | accent | 0.13% | `--vt-c-brand` |
| `outline` | `#3C3C3C1F` (on bg `#E8E8E8`) | 0.356 0 0 | border | 0.10% | `--vt-c-divider-light` |
| `vt-c-white-mute` | `#F1F1F1` | 0.958 0 0 | other | 0.25% | `--vt-c-white-mute` |

Declared brand/accent tokens: `--docsearch-primary-color` = `#5468FF` (declared, not painted on this page).

Contrast: text on background 12.61:1, muted text 4.51:1, accent 2.5:1.

Gradients in use: `-webkit-linear-gradient(315deg, rgb(66, 211, 146) 25%, rgb(100, 126, 255))`; `linear-gradient(rgb(241, 241, 241), rgb(241, 241, 241)), linear-gradient(45deg, rgb(66, 211, 146), rgb(100, 126, 255))`.

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

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Inter** | display, body | 400, 500, 600, 900 | 99.9% | webfont |
| **system-ui** | mono | 500 | 0.10% | system (stack `"Inter var experimental", "Inter var", Inter, -apple-system,`, resolved on macos) |

Declared in `@font-face` but not used to paint text on this page: Inter4CJK. Don't treat these as the page's fonts.

Scale (px): 11, 12, 13, 14.5, 15, 16, 20, 22, 76. Effective ratio ≈ 1.5 (close to a perfect fifth). Body 15px at line-height 1.6; display 76px with tracking -0.02em. Headings are sentence case. On a 390px viewport the body is 15px and display 48px.

## Layout

Spacing has no reliable single base unit; the most used steps are 2, 4, 8, 12, 15, 18, 24, 28, 32, 36, 42, 48, 208px. Sections open with about 96px of space before their first line of text. Content sits in a 960px container on a 4-column grid. Text density 0.067 (text area / page area).

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

1. **nav** (55px, bg #FFFFFF)
2. **hero** — “The JavaScript Framework” (523px, bg #FFFFFF)
3. **section** (50px, bg #FFFFFF)
4. **section** — “Efficient” (1629px, bg #FFFFFF)
5. **footer** (798px, bg #F9F9F9)

## Elevation & Depth

Style: flat. Most used shadows:

- `rgba(0, 0, 0, 0.04) 0px 1px 2px 0px, rgba(0, 0, 0, 0.06) 0px 1px 2px 0px`

## Shapes

Dominant corner radius 2px; radii in use: 2px, 8px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#42B883`, textColor `#FFFFFF`, rounded `8px`, padding `8px 16px`, height `40px`, fontFamily `Inter`, fontSize `16px`, fontWeight `600` (e.g. “Why Vue”)
- **card**: rounded `2px`, padding `0px`, backgroundColor `#F9F9F9`

## Do's and Don'ts

- Do reserve `#42B883` for primary actions and highlights; it covers only 0.13% of the painted page.
- Do set body copy in Inter at 15px / 1.6.
- Do tighten large headlines (-0.02em at 76px).
- Don't introduce font weights beyond 400, 500, 600, 900.
- Don't add drop shadows; depth comes from tone and borders.
- Do keep corners at 2px for most controls, and use the larger radii only for cards and media.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
