A modern Sphinx documentation theme with Tailwind CSS and Alpine.js

Sphinx Lumina Theme

A modern Sphinx theme that treats documentation as a first-class product experience. Clean typography, responsive layout, dark mode, and instant search — out of the box.

Documentation

Features

• Dark mode — follows system preference with manual toggle, no flash of unstyled content
• Instant search — Pagefind-powered search with keyboard navigation (⌘K)
• Responsive layout — mobile-first with collapsible sidebar and sticky table of contents
• MyST Markdown — write docs in Markdown with full Sphinx directive support
• Interactive HTTP API — OpenAPI endpoint docs with live "Try it out" panels and curl copy buttons; no Swagger UI needed
• Code blocks — syntax highlighting with one-click copy
• Self-hosted fonts — Source Sans 3 and JetBrains Mono, no external CDN calls
• Version switcher — dropdown to navigate between documentation versions, loaded from a JSON URL
• Customizable — accent colors, navigation links, social links, and more via conf.py

Quick Start

Requires Python 3.12+ and Sphinx 8.0+.

pip install sphinx-lumina-theme

or with uv:

uv add sphinx-lumina-theme

Set the theme in your conf.py:

html_theme = "lumina"

Build your docs:

uv run sphinx-build docs docs/_build/html

That's it. For MyST Markdown setup and configuration options, see the Getting Started guide.

Configuration

All options go in html_theme_options in your conf.py. Every option has a sensible default — you only need to set what you want to change.

html_theme_options = {
    "accent_color": "#10b981",
    "dark_mode_default": "auto",       # "auto", "light", or "dark"
    "nav_links": "Guide=/guide, API=/api",
    "source_repository": "https://github.com/you/your-repo",
    "social_links": "github=https://github.com/you",
    "api_base_url": "https://api.example.com/v1",  # enables interactive API features
}

See the full Configuration reference for all available options.
