### What is the Microsoft Azure design system?

The design system on this page is azure.microsoft.com’s, as measured on November 4, 2026: Segoe UI Variable Display type, #0078D4 as the main color and 8px corners, written down as a DESIGN.md. It is not Microsoft Azure’s own documentation.

### What is Microsoft Azure built with?

Microsoft Azure’s website (azure.microsoft.com) is built with Adobe Experience Manager, jQuery, Lit, React and Fluent UI. The full tech stack Sitepeel found: jQuery, Lit, React, Meta Pixel, TikTok Pixel, Adobe Experience Manager, Vidyard, Microsoft Advertising, Microsoft Clarity and Reddit Pixel. Measured on November 4, 2026.

### What is the Microsoft Azure DESIGN.md?

A plain-text file with Microsoft Azure’s measured colors, type, spacing, corners and components as tokens, plus short rules, in the DESIGN.md format Google published with Stitch. Your AI coding agent reads it and builds in this style. More about DESIGN.md.

### How do I use it with Claude Code or Cursor?

Download the file and put it in your project’s root folder, then ask your agent to follow DESIGN.md. Step-by-step guides: Claude Code, Cursor, Codex, GitHub Copilot.

### Is this Microsoft Azure’s official design system?

No. Sitepeel measured it from azure.microsoft.com’s public page on November 4, 2026. It is an independent analysis, not made or approved by Microsoft Azure.

### Can I use Microsoft Azure’s style in my own product?

Use it to learn, prototype and compare. For a real product, make the style your own, and never copy Microsoft Azure’s logo, name, pictures or text.

### How accurate are the values?

Each value was measured on the rendered page after it fully loaded, on desktop and mobile: colors where they appear, type with tracking, spacing, corners, shadows and hover states. Sites change, so check the date at the top.

# Microsoft Azure Design System

## Overview

Microsoft Azure describes itself as: “Invent with purpose, realize cost savings, and make your organization more efficient with Microsoft Azure’s open and flexible cloud computing platform.” The interface is dark, built on **Deep Blue (#002948)** with **White (#FFFFFF)** text, and **Blue (#0078D4)** as the main accent.

Type is set in **Segoe UI Variable Display** and **Segoe UI Variable Text**. Headlines run large with tight negative tracking; body text is 16px. Depth comes from soft drop shadows. Corners are mostly 8px.

Measured from [azure.microsoft.com/en-us](https://azure.microsoft.com/en-us) (the site sent our reader to its /en-us version; azure.microsoft.com was asked for) on November 4, 2026 at 1440×900 and 390×844 from 287 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 12 roles.

- **Deep Blue (#002948):** Page background. Token `background`.
- **White (#FFFFFF):** Primary text and headings, seen 13 times. Token `on-surface`.
- **Cool Snow (#F4FAFD):** Secondary text, seen 5 times. Token `on-surface-variant`.
- **Slate (#616161):** Muted text and metadata, seen 44 times. Token `on-surface-muted`.
- **Dark Blue 10% (#0055971A):** Translucent fill for cards and controls, seen 9 times. Token `overlay`.
- **Near Black (#000000):** Borders and dividers, seen 1 time. Token `outline`.
- **Deep Blue (#17253D):** Secondary dividers, seen 1 time. Token `outline-variant`, CSS `--ds-comp-color-input-field-label-text-default`.
- **Blue (#0078D4):** Primary buttons and calls to action, seen 12 times. Token `primary`, CSS `--root-color-brilliant-blue-500`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **White (#FEFEFE):** High-contrast fills, seen 4 times. Token `inverse-surface`.
- **Light Blue (#B3DAF0):** Secondary buttons, seen 1 time. Token `secondary`.
- **Dark Indigo (#05037B):** Accent in logos and imagery. Token `tertiary`.

## Typography

**Segoe UI Variable Display**, **Segoe UI Variable Text** and **Segoe UI** share the interface. Fallback stack: `Segoe UI Variable Display, Segoe UI, segoeui, Helvetica Neue`. Other loaded fonts: MWF-FLUENT-ICONS, SegoeUI, FabricMDL2Icons.

- **headline-display:** Segoe UI Variable Display 62px at weight 500, line height 1.16, tracking -0.025em (40px on mobile). Page title (h1).
- **headline-lg:** Segoe UI Variable Display 48px at weight 500, line height 1.17, tracking -0.025em. Section headings (h2).
- **headline-md:** Segoe UI Variable Display 32px at weight 500, line height 1.25, tracking -0.015em. Sub-section headings.
- **headline-sm:** Segoe UI Variable Display 24px at weight 500, line height 1.33, tracking -0.01em. Card and feature titles.
- **title-lg:** Segoe UI Variable Display 20px at weight 600, line height 1.4 (18px on mobile). Small titles.
- **body-md:** Segoe UI Variable Text 16px at weight 400, line height 1.5, tracking -0.03em. Body text.
- **body-sm:** Segoe UI 11px at weight 400, line height 1.45, tracking -0.044em. Secondary and small text.
- **label-lg:** Segoe UI Variable Text 16px at weight 600, line height 1.5. Large buttons and tabs.
- **label-md:** Segoe UI Variable Text 15px at weight 600, line height 1.47, tracking -0.02em. Buttons, navigation and labels.
- **label-sm:** Segoe UI Variable Text 14px at weight 600, line height 1.43. Small labels and badges.

## Layout

Spacing is mostly on a 4px grid (88% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** xs 4px, sm 8px, md 16px, lg 24px, xl 36px.
- **Gaps:** 8px is the most common gap in flex and grid layouts.
- **Page margin:** 72px on each side of full-width sections.
- **Breakpoints:** 540px, 859px, 859.98px, 860px, 1083px, 1084px, 1400px, 1440px.

## Elevation & Depth

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

- `rgba(0, 0, 0, 0.12) 0px 0px 2px 0px, rgba(0, 0, 0, 0.14) 0px 1.008px 2px 0px`
- `rgba(0, 0, 0, 0.12) 0px 0px 2px 0px, rgba(0, 0, 0, 0.14) 0px 2px 4px 0px`

## Shapes

Most elements use 8px corners. Measured radii, most used first:

- **sm (8px):** 68 elements.
- **xl (200px):** 44 elements.
- **lg (24px):** 24 elements.
- **xs (3px):** 16 elements.
- **md (16px):** 5 elements.

## Components

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

- **button-primary (“Get started with Azure”):** #0078D4 fill, #FFFFFF text, 13px/400, 3px radius, padding 4px 8px 12px 8px.
- **button-primary-hover:** background #006DC1, text #FFFFFF on hover.
- **button-secondary (“Ask Microsoft​”):** #F4FAFD fill, #000000 text, 14px/400, 8px radius, padding 16px, border 1px solid #CBE6F4, shadow `rgba(0, 0, 0, 0.12) 0px 0px 2px 0px, rgba(0, 0, 0, 0.14) 0px 8px 16px 0px`.
- **button-tertiary (“Get started with Azure”):** #B3DAF0 fill, #0E1726 text, 15px/600, 8px radius, padding 12px 16px.
- **button-ghost (“Explore”):** transparent fill, #262626 text, 13px/400, padding 1px 8px.
- **input-field (“Ask a question about Azure.”):** transparent fill, #000000 text, 16px/400, 8px radius, padding 20px 60px 20px 16px.
- **card:** #F4FAFD fill, #17253D text, 16px/400, padding 96px 0px.
- **link:** transparent fill, #616161 text, padding 0px.

## Do's and Don'ts

- Do use #002948 for the page.
- Do keep text in 3 levels: #FFFFFF, #F4FAFD, #616161.
- Do reserve #0078D4 for primary actions and key highlights.
- Do set headlines in Segoe UI Variable Display with tight tracking (-0.025em).
- Do reuse the measured spacing steps (8px, 16px, 24px).
- Do use 8px corners on most elements; larger surfaces also use 200px, 24px and 3px.
- Don't use #616161 for body text; it reaches 2.40:1 on #002948. Keep it for large text or metadata.
- Don't introduce new font families beyond Segoe UI Variable Display, Segoe UI Variable Text and Segoe UI.
- Don't use #0078D4 for large backgrounds or body text.
- Don't make interface transitions slower than 0.2s.

## Motion

Interface transitions are quick: 0.125s, 0.2s. Longer ambient animations run 1.2s, 0.8s, 2.4s.

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