# Docker Design System

## Overview

Docker describes itself as: “Run AI agents and containers safely, anywhere. Docker gives builders trusted sandboxes, governance, and a secure supply chain for modern software.” The interface is light, built on **Snow (#F9FAFB)** with **Deep Blue (#2C333F)** text, and **Vivid Blue (#2560FF)** as the main accent.

Type is set in **Repro** and **Inter**, with **ui-monospace** for code. Headlines run large with tight negative tracking; body text is 16px. Depth comes from soft drop shadows. Corners are mostly 18px.

Measured from [docker.com](https://www.docker.com/) on October 21, 2026 at 1440×900 and 390×844 from 289 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 18 roles, plus gradient stops #283045.

- **Teal (#34D399):** Success and positive states, seen 8 times. Token `success`.
- **Vivid Red (#EF4444):** Errors and destructive states, seen 2 times. Token `error`.
- **Vivid Amber (#FFBD2E):** Warnings and highlights, seen 1 time. Token `warning`.

## Typography

**Repro**, **Inter**, **ABC Repro** and **ui-monospace** (monospace) share the interface. Fallback stack: `Repro, Helvetica, Arial, sans-serif`.

- **headline-display:** Repro 64px at weight 500, line height 1.05, tracking -0.03em (36px on mobile). Page title (h1).
- **headline-lg:** Repro 60px at weight 500, line height 1, tracking -0.025em. Section headings (h2).
- **headline-md:** Inter 22px at weight 500, line height 1.25, tracking -0.012em. Sub-section headings.
- **headline-sm:** Inter 20px at weight 500, line height 1.5, tracking -0.013em. Card and feature titles.
- **body-md:** Inter 16px at weight 400, line height 1.5. Body text.
- **body-lg:** ABC Repro 19px at weight 600, line height 1.3, tracking -0.012em. Lead paragraphs.
- **body-sm:** Inter 14px at weight 400, line height 1, tracking -0.011em. Secondary and small text.
- **caption:** Inter 12px at weight 400, line height 1.3, tracking -0.012em. Captions and fine print.
- **label-lg:** Inter 14px at weight 500, line height 1.3, tracking -0.011em. Large buttons and tabs.
- **label-md:** Inter 13px at weight 600, line height 1.2, tracking 0.01em. Buttons, navigation and labels.
- **label-sm:** Inter 12px at weight 500, line height 1.3, tracking -0.012em. Small labels and badges.
- **code:** ui-monospace 12.5px at weight 400, line height 1.5. Code and technical values.

## Layout

Spacing is mostly on a 4px grid (80% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** xs 3.5px, sm 8px, md 12px, lg 20px, xl 40px.
- **Gaps:** 8px is the most common gap in flex and grid layouts.
- **Breakpoints:** 400px, 425px, 426px, 500px, 550px, 767px, 768px, 769px, 896px, 900px.

## Elevation & Depth

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

- `rgba(15, 23, 42, 0.03) 0px 1px 2px 0px`

Hairline rings and inset highlights also appear: `rgb(67, 76, 95) 0px 0px 1px 1px inset`.

## Shapes

Most elements use 18px corners. Measured radii, most used first:

- **xl (18px):** 28 elements.
- **sm (2px):** 24 elements.
- **full (9999px):** 12 elements.
- **md (4px):** 8 elements.
- **lg (8px):** 8 elements.

## Components

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

- **button-primary (“Buy now”):** #2560FF fill, #FFFFFF text, 12px/500, 4px radius, padding 8px 12px, border 1px solid #003DB5, shadow `rgb(192, 224, 250) 0px 0px 1px 1px inset`.
- **button-outline (“Get started”):** #FFFFFF fill, #000000 text, 12px/500, 4px radius, padding 8px 12px, border 1px solid #A9B4C6, shadow `rgba(0, 0, 0, 0) 0px 0px 1px 1px inset`.
- **button-secondary (“Reject All”):** #1D63ED fill, #FFFFFF text, 13.008px/600, 2px radius, padding 12px 10px, border 1px solid #1D63ED.
- **card:** #FFFFFF fill, #0B1220 text, 16px/400, 18px radius, padding 28px 28px 0px 28px, border 1px solid #E7EAEF, shadow `rgba(15, 23, 42, 0.03) 0px 1px 2px 0px`.
- **link:** transparent fill, #2C333F text, padding 0px.

## Do's and Don'ts

- Do use #F9FAFB for the page and lift surfaces in small steps: #FFFFFF, #F0F0F0, #D6DCE6.
- Do keep text in 4 levels: #2C333F, #000000, #475569, #94A3B8.
- Do reserve #2560FF for primary actions and key highlights.
- Do set headlines in Repro with tight tracking (-0.03em).
- Do reuse the measured spacing steps (8px, 12px, 20px).
- Do use 18px corners on most elements; larger surfaces also use 2px, 4px and 8px.
- Don't use #94A3B8 for body text; it reaches 2.5:1 on #F9FAFB. Keep it for large text or metadata.
- Don't introduce new font families beyond Repro, Inter, ABC Repro and ui-monospace.
- Don't use #2560FF for large backgrounds or body text.
- Don't make interface transitions slower than 0.3s.

## Motion

Interface transitions are quick: 0.25s, 0.3s, 0.1s. Longer ambient animations run 1s.

- **Easing:** `ease`, `cubic-bezier(0.4, 0, 0.2, 1)`.
