# Grubhub Mobile — Design System

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

Grubhub Mobile — palette measured from official store listing screenshots (colors only; no font claims). Type scale shown is the platform HIG default.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#FF5500` |
| accent | `#FF5500` |
| link | `#FF5500` |
| button_bg | `#FF5500` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#FF5500` — 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 `#FF5500` — one role, not several (your action color).
- **accent** `#FF5500` — 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): `#F3E3CB` 40.4% · `#F8F4F1` 27.7% · `#CF8B5A` 17.4% · `#562B1F` 14.5%

## Typography


| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 42px / 700 · lh 48px |
| body | 24px / 400 · lh 32px |
| small | 22px / 500 · lh 28px |

- Weight ladder: 400 · 500 · 700 — use these exact measured weights, not the 400/600 defaults.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 3px, 4px, 8px, 12px, 13px, 15px, 16px, 20px, 24px, 32px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 12px
- card: 42px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#262626` / `#FFFFFF` | 1px solid rgb(38, 38, 38) | 42px | 0px 16px 0px 16px | 400 14px | none |
| secondary | `#FFFFFF` / `#1A1A19` | 1px solid rgb(219, 217, 215) | 42px | 0px 16px 0px 16px | 400 14px | none |

**States (measured, not guessed)**

- primary hover: border `1px solid rgb(54, 40, 198)` · background `#3628C6`
- primary focus: border `1px solid rgb(54, 40, 198)` · background `#3628C6`
- secondary hover: background `#F5F3F1`

## Shadows (elevation)
- subtle: `rgba(38, 38, 38, 0.1) 0px 0px 0px 1px, rgba(38, 38, 38, 0.1) 0px 1px 8px 0px`
- card: `rgba(38, 38, 38, 0.1) 0px 0px 0px 1px, rgba(38, 38, 38, 0.1) 0px 1px 12px 0px`

## Motion
- durations: 200ms (dominant) · 100ms
- easings: `ease` (dominant)
- animated properties: color, border-color, background

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

## Layout (measured)
- common grid: 4-col
- nav: 78px fixed · bg #FFFFFF

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 2879 | 518 | 4 | — | 32/32 | — |
| 3399 | 910 | 4 | — | 32/32 | 50/13/25/13 |
| 4382 | 294 | 2 | — | 32/32 | 80/20 |

## Motion choreography (measured)
Load order: `div.mainNav` @0ms → `div.notifications` @0ms → `nav.mainNav` @418ms

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

## Components (measured)
- input: h 48px · r 42px · bg #FFFFFF · placeholder #575655
  - focus ring: `1px auto rgb(87, 42, 248)` — this exact construction, don't invent your own

## Responsive (measured)
- breakpoints: 576px · 768px · 800px · 992px · 1200px · 1300px
- mobile (390px): hero 34px · body 14px · 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.
