# Vue.js Design System

## Overview

Vue.js describes itself as: “Vue.js - The Progressive JavaScript Framework” The interface is dark, built on **Charcoal (#1A1A1A)** with **Mist (#E1E1E1)** text, and **Teal (#42D392)** as the main accent.

Type is set in **Inter var experimental**. Headlines run large with tight negative tracking; body text is 14.5px. Depth comes from soft drop shadows. Corners are mostly 2px.

Measured from [vuejs.org](https://vuejs.org/) on October 21, 2026 at 1440×900 and 390×844 from 234 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 12 roles, plus gradient stops #42D392, #647EFF.

- **Charcoal (#1A1A1A):** Page background, seen 3 times. Token `background`, CSS `--vt-c-black`.
- **Mist (#E1E1E1):** Primary text and headings. Token `on-surface`.
- **Light Blue (#AAC8E4):** Secondary text, seen 3 times. Token `on-surface-variant`, CSS `--vt-c-indigo-light`.
- **Gray (#979797):** Muted text and metadata, seen 11 times. Token `on-surface-muted`, CSS `--vt-c-text-2`.
- **Graphite (#242424):** Raised areas one step from the page, seen 13 times. Token `surface-container-low`, CSS `--vt-c-black-soft`.
- **Graphite (#2F2F2F):** Cards and panels, seen 3 times. Token `surface-container`, CSS `--vt-c-black-mute`.
- **Slate 65% (#545454A6):** Borders and dividers, seen 1 time. Token `outline`.
- **Slate 48% (#5454547A):** Secondary dividers, seen 1 time. Token `outline-variant`.
- **Teal (#42D392):** Brand accent (CSS variable), seen 2 times. Token `primary`, CSS `--vt-c-green-light`.
- **Near Black (#000000):** Text and icons on primary. Token `on-primary`.
- **Teal (#33A06F):** Brand accent (CSS variable), seen 12 times. Token `secondary`.
- **Teal (#42B883):** Success and positive states, seen 3 times. Token `success`, CSS `--vt-c-green`.

## Typography

**Inter var experimental** carries the whole interface. Fallback stack: `Inter var experimental, Inter var, Inter, -apple-system`. Other loaded fonts: Inter.

- **headline-display:** Inter var experimental 76px at weight 900, line height 1.25, tracking -0.02em (48px on mobile). Page title (h1).
- **headline-lg:** Inter var experimental 20px at weight 600, line height 1.2, tracking -0.02em. Section headings (h2).
- **body-md:** Inter var experimental 14.5px at weight 400, line height 1.67, tracking 0.014em. Body text.
- **body-lg:** Inter var experimental 15px at weight 400, line height 1.6, tracking 0.013em. Lead paragraphs.
- **body-sm:** Inter var experimental 11px at weight 400, line height 2.18, tracking 0.018em. Secondary and small text.
- **label-lg:** Inter var experimental 16px at weight 400, line height 1.5, tracking 0.013em. Large buttons and tabs.
- **label-md:** Inter var experimental 13px at weight 500, tracking 0.015em. Buttons, navigation and labels.
- **label-sm:** Inter var experimental 12px at weight 500, line height 1.67, tracking 0.017em. Small labels and badges.

## Layout

Spacing does not follow a strict grid: 61% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 4px, sm 8px, md 12px, lg 18px, xl 42px.
- **Sections:** 96px vertical padding between major sections.
- **Container:** content is capped at 960px.
- **Page margin:** 32px on each side of full-width sections.

## Elevation & Depth

Raised elements use soft drop shadows. The most used recipes:

- `rgba(0, 0, 0, 0.04) 0px 1px 2px 0px, rgba(0, 0, 0, 0.06) 0px 1px 2px 0px`
- `rgba(0, 0, 0, 0.1) 0px 12px 32px 0px, rgba(0, 0, 0, 0.08) 0px 2px 6px 0px`

## Shapes

Most elements use 2px corners. Measured radii, most used first:

- **xs (2px):** 48 elements.
- **md (8px):** 20 elements.
- **full (9999px):** 8 elements.
- **sm (4px):** 4 elements.
- **lg (11px):** 4 elements.
- **xl (40px):** 4 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“Get Security Updates for Vue 2”):** transparent fill, #AAC8E4 text, 16px/500, 8px radius, padding 8px 18px.
- **button-primary-hover:** background #3A3A3A, text #AAC8E4 on hover.
- **button-secondary (“Get Started”):** #2F2F2F fill, #AAC8E4 text, 16px/500, 8px radius, padding 8px 18px.
- **button-secondary-hover:** background #3A3A3A, text #AAC8E4 on hover.
- **button-outline (“Become a Sponsor”):** #242424 fill, #EBEBEB61 text, 11px/400, 2px radius, padding 0px.
- **button-ghost (“Search Ctrl K”):** transparent fill, #EBEBEB99 text, 16px/500, 40px radius, padding 0px 8px.
- **link:** transparent fill, #FFFFFFDE text, padding 0px.

## Do's and Don'ts

- Do use #1A1A1A for the page and lift surfaces in small steps: #242424, #2F2F2F.
- Do keep text in 3 levels: #E1E1E1, #AAC8E4, #979797.
- Do use #42D392 as the brand accent: header, logo and key highlights.
- Do set headlines in Inter var experimental with tight tracking (-0.02em).
- Do reuse the measured spacing steps (8px, 12px, 18px).
- Do use 2px corners on most elements; larger surfaces also use 8px, 4px and 11px.
- Don't introduce new font families beyond Inter var experimental.
- Don't use #42D392 for large backgrounds or body text.
- Don't make interface transitions slower than 0.5s.

## Motion

Interface transitions are quick: 0.25s, 0.5s, 0.2s.

- **Easing:** `ease`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
