Decoded design system

LinkedIn Mobile's decoded design system: background #FFFFFF, text #000000, accent #0A66C2, link #0A66C2, primary #0A66C2; type scale h1 48px / h2 32px / body 20px; 6px spacing base; 12px base radius. The single interactive/action color is #0A66C2 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #0A66C2 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, link, button_bg are all #0A66C2 — one role, not several (the action color).
• accent #0A66C2 — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.

# LinkedIn Mobile — Design System

> light, consumer, high — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#0A66C2` |
| accent | `#0A66C2` |
| link | `#0A66C2` |
| button_bg | `#0A66C2` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#0A66C2` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent`, `link`, `button_bg` are all `#0A66C2` — one role, not several (your action color).
- **accent** `#0A66C2` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 56.5% · `#5C6F7C` 21.7% · `#F4EFE6` 9.3% · `#BCC2C3` 7.3%

## Typography

- Heading: **-apple-system**
- Body: **-apple-system**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 48px / 400 · lh 60px |
| h2 | 32px / 400 · lh 40px |
| body | 20px / 400 · lh 30px |
| small | 16px / 600 · lh 24px |

- Weight ladder: 400 · 600 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** -apple-system — system font, no web load needed.

## Spacing
- base unit: 6px (inferred from the measured scale)
- measured scale: 6px, 7px, 8px, 12px, 16px, 24px, 32px, 48px, 60px, 64px — snap all gaps/padding to these
- section rhythm: 60px top/bottom padding per section (measured)

## Radius
- base: 12px
- button: 24px
- card: 24px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#0A66C2` / `#FFFFFF` | none | 24px | 12px 24px 12px 24px | 600 16px | rgba(0, 0, 0, 0) 0px 0px 0px 1px |
| secondary | `rgba(0, 0, 0, 0)` / `rgba(0, 0, 0, 0.6)` | none | — | 0px 8px 0px 8px | 600 16px | none |

**States (measured, not guessed)**

- primary hover: background `#004182`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: color `rgba(0, 0, 0, 0.9)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0.75) 0px 0px 0px 1px`
- card: `rgba(0, 0, 0, 0.3) 0px 4px 12px 0px`
- button: `rgba(0, 0, 0, 0) 0px 0px 0px 1px`

## Motion
- durations: 336ms (dominant) · 167ms · 334ms
- easings: `cubic-bezier(0.34, 0, 0.21, 1)` (dominant) · `cubic-bezier(0.4, 0, 0.2, 1)`
- animated properties: opacity, background-color, box-shadow, color

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

| Token | Value |

_…and 108 more measured on the page._

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)

## Motion choreography (measured)
Load order: `div.cta-modal` @0ms → `div.cta-modal` @0ms → `ul.slide-list__list` @0ms → `div.global-alert-banner` @22ms
- scroll reveal: 4 elements rest at opacity 0, animate in over 0.336s cubic-bezier(0.34, 0, 0.21, 1) (4 revealed during the drive).
- overlay dialog (auto-opened): panel #F1F8FA · r 8px · shadow rgba(0, 0, 0, 0.3) 0px 4px 12px 0px

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)
- link: #FFFFFF · underline

## Responsive (measured)
- breakpoints: 768px · 992px · 1161px
- mobile (390px): hero 32px · body 16px · nav: inline

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
