# Atlassian Design System

## Overview

Atlassian describes itself as: “Atlassian's team collaboration software like Jira, Confluence and Trello help teams organize, discuss, and complete shared work.” The interface is dark, built on **Charcoal (#101214)** with **White (#FFFFFF)** text, and **Vivid Blue (#1868DB)** as the main accent.

Type is set in **Charlie Display** and **Charlie Text**. Headlines run large with tight negative tracking; body text is 16px. The surface language is flat. Controls are pill-shaped.

Measured from [atlassian.com](https://www.atlassian.com/) on October 21, 2026 at 1440×900 and 390×844 from 396 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 8 roles.

- **Charcoal (#101214):** Page background, seen 4 times. Token `background`.
- **White (#FFFFFF):** Primary text and headings, seen 34 times. Token `on-surface`, CSS `--ds-background-input-pressed`.
- **Near Black 50% (#00000080):** Translucent fill for cards and controls, seen 1 time. Token `overlay`.
- **Vivid Blue (#1868DB):** Primary buttons and calls to action, seen 19 times. Token `primary`, CSS `--ds-chart-information-hovered`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Light Teal (#BAF3DB):** Brand accent (CSS variable), seen 24 times. Token `secondary`.
- **Teal (#7EE2B8):** Brand accent (CSS variable), seen 24 times. Token `tertiary`.
- **Vivid Amber (#DF9800):** Warnings and highlights, seen 5 times. Token `warning`.

## Typography

**Charlie Display** and **Charlie Text** share the interface. Fallback stack: `Charlie Display, -apple-system, BlinkMacSystemFont, Segoe UI`. Other loaded fonts: Atlassian Mono.

- **headline-display:** Charlie Display 64px at weight 500, line height 1.04, tracking -0.02em (44px on mobile). Page title (h1).
- **headline-lg:** Charlie Display 48px at weight 500, line height 1.16, tracking -0.02em (32px on mobile). Section headings (h2).
- **headline-md:** Charlie Display 40px at weight 500, line height 1.2, tracking -0.01em. Sub-section headings.
- **headline-sm:** Charlie Display 32px at weight 500, line height 1.24 (64px on mobile). Card and feature titles.
- **title-lg:** Charlie Display 24px at weight 400, line height 1.36, tracking -0.01em. Small titles.
- **body-md:** Charlie Text 16px at weight 400. Body text.
- **body-lg:** Charlie Text 18px at weight 400. Lead paragraphs.
- **body-sm:** Charlie Display 14px at weight 400, line height 1, tracking 0.03em. Secondary and small text.
- **label-lg:** Charlie Text 14px at weight 700, line height 1. Large buttons and tabs.
- **label-md:** Charlie Text 13px at weight 700. Buttons, navigation and labels.
- **label-sm:** Charlie Display 12px at weight 500, line height 1.3, tracking 0.067em. Small labels and badges.

## Layout

Spacing does not follow a strict grid: 64% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 4px, sm 8px, md 16px, lg 19px, xl 40px.
- **Sections:** 48px vertical padding between major sections.
- **Gaps:** 40px is the most common gap in flex and grid layouts.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from color contrast.

## Shapes

Interactive controls are pill-shaped. Measured radii, most used first:

- **full (9999px):** 44 elements.
- **sm (3px):** 24 elements.
- **md (20px):** 24 elements.

## Components

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

- **button-primary (“Get started with Jira”):** #1868DB fill, #FFFFFF text, 20px/400, 10000px radius, padding 10px 26px.
- **button-primary-hover:** background #123263, text #FFFFFF on hover.
- **button-secondary (“search”):** #F8F8F8 fill, #000000 text, 13.3333px/400, 50% radius, padding 8px.
- **input-field (“Choose your language”):** transparent fill, #42526E text, 14px/400, padding 0px.
- **card:** #4C6B1F fill, #292A2E text, 16px/400, padding 0px.
- **link:** transparent fill, #101214 text, padding 0px.

## Do's and Don'ts

- Do use #101214 for the page.
- Do reserve #1868DB for primary actions and key highlights.
- Do set headlines in Charlie Display with tight tracking (-0.02em).
- Do reuse the measured spacing steps (8px, 16px, 19px).
- Do make buttons and chips fully rounded (9999px); most other elements use 3px corners.
- Don't add drop shadows for depth; use borders and contrast.
- Don't introduce new font families beyond Charlie Display and Charlie Text.
- Don't use #1868DB for large backgrounds or body text.
- Don't make interface transitions slower than 0.5s.

## Motion

Interface transitions are quick: 0.25s, 0.15s, 0.5s.

- **Easing:** `ease-in-out`, `cubic-bezier(0.4, 0, 0, 1)`, `cubic-bezier(0.6, 0.01, 0.8, 0.6)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
