Do’s and don’ts

Rules written from the measurements, so a coding agent stays on style.

Use #FFFFFF for the page and lift surfaces in small steps: #FFFFFFF2.
Keep text in 3 levels: #737373, #0A0A0A, #0A0A0F.
Reserve #7FFF6E for primary actions and key highlights.
Keep spacing on the 4px grid.
Use 10px corners on most elements; larger surfaces also use 8px.
Introduce new font families beyond Space Grotesk, IBM Plex Sans and JetBrains Mono.
Use #7FFF6E for large backgrounds or body text.
Make interface transitions slower than 0.2s.

# dotgit.dev Design System

## Overview

dotgit.dev describes itself as: “Watch what happens inside .git/ when you run init, add, commit, branch or merge. 38 interactive lessons plus a free browser playground — no setup needed.” The interface is light, built on **White (#FFFFFF)** with **Slate (#737373)** text, and **Light Green (#7FFF6E)** as the main accent.

Type is set in **Space Grotesk** and **IBM Plex Sans**, with **JetBrains Mono** for code. Headlines run large; body text is 16px. Depth comes from soft drop shadows. Corners are mostly 10px.

Measured from [dotgit.dev](https://dotgit.dev/) on October 29, 2026 at 1440×900 and 390×844 from 116 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 8 roles.

- **White (#FFFFFF):** Page background, seen 9 times. Token `background`.
- **Slate (#737373):** Primary text and headings, seen 43 times. Token `on-surface`.
- **Near Black (#0A0A0A):** Headings and emphasis, seen 14 times. Token `on-surface-strong`.
- **Charcoal (#0A0A0F):** Secondary text, seen 3 times. Token `on-surface-variant`, CSS `--cta-foreground`.
- **White 95% (#FFFFFFF2):** Raised areas one step from the page, seen 1 time. Token `surface-container-low`.
- **Mist (#E5E5E5):** Borders and dividers, seen 9 times. Token `outline`.
- **Light Green (#7FFF6E):** Primary buttons and calls to action, seen 12 times. Token `primary`.
- **Charcoal (#0A0A0F):** Text and icons on primary. Token `on-primary`.

## Typography

**Space Grotesk**, **IBM Plex Sans** and **JetBrains Mono** (monospace) share the interface. Fallback stack: `Space Grotesk, sans-serif`.

- **headline-display:** Space Grotesk 60px at weight 700, line height 1.25 (36px on mobile). Page title (h1).
- **headline-lg:** Space Grotesk 30px at weight 700, line height 1.25 (24px on mobile). Section headings (h2).
- **body-md:** IBM Plex Sans 16px at weight 400, line height 1.5. Body text.
- **body-sm:** IBM Plex Sans 14px at weight 400, line height 1.43. Secondary and small text.
- **caption:** IBM Plex Sans 12px at weight 400, line height 1.33. Captions and fine print.
- **label-md:** Space Grotesk 16px at weight 600, line height 1.63. Buttons, navigation and labels.
- **code:** JetBrains Mono 14px at weight 600, line height 1.43. Code and technical values.

## Layout

Spacing follows a 4px grid: 94% of measured gaps and paddings are multiples of 4px.

- **Scale:** xs 2px, sm 8px, md 12px, lg 20px, xl 56px.
- **Sections:** 56px vertical padding between major sections.
- **Gaps:** 8px is the most common gap in flex and grid layouts.
- **Container:** content is capped at 896px.

## Elevation & Depth

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

- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.05) 0px 1px 2px 0px`

## Shapes

Most elements use 10px corners. Measured radii, most used first:

- **md (10px):** 24 elements.
- **sm (8px):** 16 elements.

## Components

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

- **button-primary (“Start learning”):** #7FFF6E fill, #0A0A0F text, 16px/400, 8px radius, padding 0px.
- **button-outline (“▶ playground”):** #FFFFFF fill, #0A0A0A text, 14px/500, 8px radius, padding 8px 16px, border 1px solid #E5E5E5, shadow `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.05) 0px 1px 2px 0px`.
- **button-ghost (“Dismiss”):** transparent fill, 16px/400, padding 12px.
- **card:** transparent fill, 16px/400, 10px radius, padding 20px.
- **link:** transparent fill, #737373 text, padding 0px.

## Do's and Don'ts

- Do use #FFFFFF for the page and lift surfaces in small steps: #FFFFFFF2.
- Do keep text in 3 levels: #737373, #0A0A0A, #0A0A0F.
- Do reserve #7FFF6E for primary actions and key highlights.
- Do keep spacing on the 4px grid.
- Do use 10px corners on most elements; larger surfaces also use 8px.
- Don't introduce new font families beyond Space Grotesk, IBM Plex Sans and JetBrains Mono.
- Don't use #7FFF6E for large backgrounds or body text.
- Don't make interface transitions slower than 0.2s.

## Motion

Interface transitions are quick: 0.15s, 0.2s.

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

What you can build with it

Landing pages, pricing tables, dashboards: your AI coding agent builds them in this style, with these colors, fonts, spacing and buttons instead of its defaults.

Download DESIGN.md, put it in your project’s root folder, then ask your agent for a page.

Prompt · DESIGN.md attached

Build a landing page for my product. Follow for every color, font, spacing value, corner and button.

Guides

Need a page behind a login?

The DESIGN.md generator Chrome extension makes one from any page you have open, including dashboards and pages behind a login.

FAQ

dotgit.dev design system questions

What font does dotgit.dev use?

dotgit.dev’s website uses Space Grotesk (weights 600 and 700) and IBM Plex Sans (weight 400), with JetBrains Mono for code. Page titles are 60px at weight 700 (36px on phones) and body text is 16px. Measured on October 29, 2026.

What are the dotgit.dev colors and hex codes?

On dotgit.dev: #FFFFFF (white) for the background, #737373 (slate) for text and #7FFF6E (light green) as the main accent. The color palette above lists all 8 colors with their hex codes and where each one is used.

What is the dotgit.dev design system?

The design system on this page is dotgit.dev’s, as measured on October 29, 2026: Space Grotesk type, #7FFF6E as the main color, 10px corners and a 4px spacing grid, written down as a DESIGN.md. It is not dotgit.dev’s own documentation.

What is the dotgit.dev DESIGN.md?

A plain-text file with dotgit.dev’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 dotgit.dev’s official design system?

No. Sitepeel measured it from dotgit.dev’s public page on October 29, 2026. It is an independent analysis, not made or approved by dotgit.dev.

Can I use dotgit.dev’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 dotgit.dev’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.
