md2html-tailwind4

A Python package that converts Markdown to clean, styled HTML using Tailwind CSS 4 classes.

Designed for projects that render HTML inside a Tailwind-powered frontend (Django, FastAPI, static sites, etc.). No build step required — just pass in Markdown, get back ready-to-render HTML.

Features

• Converts Markdown to HTML with full Tailwind CSS 4 class annotations
• Configurable font size scale (sm, base, lg)
• Abbreviations (abbr) with dotted underline tooltip
• Definition lists (dl/dt/dd)
• Footnotes ([^1] syntax)
• Admonition callout boxes (!!! note, !!! warning, !!! danger, etc.) with color-coded Tailwind styling
• Inline/block math parsing via pymdownx.arithmatex (e.g. $\\rightarrow$) with automatic MathJax loader injection
• Heading anchor IDs auto-generated via toc extension
• List items immediately following a paragraph (no blank line) render correctly
• Responsive tables with overflow scrolling
• Audio table support (3-column tables with media URLs become interactive audio players)
• Automatically escapes Django template delimiters ({{ }}, {% %}) inside code blocks
• External links get target="_blank" and rel="noopener noreferrer" automatically
• Dark mode support via Tailwind's dark: variants
• CLI tool included

Installation

pip install md2html-tailwind4

Usage

Python API

from md2html_tailwind4 import Converter

# font_size: 'sm' | 'base' (default) | 'lg'
converter = Converter(font_size='sm')
html = converter.convert_md_to_html("# Hello\n\nThis is **Markdown**.")
print(html)

Command Line

md2html input.md output.html

# Use a smaller font size
md2html input.md output.html --font-size sm

Font Size Scales

Scale	Heading 1	Body text	Code block
sm	text-xl → text-3xl	text-sm	text-xs
base (default)	text-2xl → text-4xl	text-base	text-sm
lg	text-3xl → text-5xl	text-lg	text-base

HTML Output & Integration

The generated HTML is production-ready with:

• Tailwind CSS 4 classes already applied (no build step needed)
• MathJax 3 automatically injected when math expressions detected
• Dark mode support via dark: variants
• Responsive design for all elements
• Security hardening (Django template escaping, external link attributes)

See HTML_HANDLING.md for detailed integration guides with Django, FastAPI, and more.

Math Support

Format math expressions with $...$ or \(...\):

Pricing: $4.99 \rightarrow $14.99
Physics: $E=mc^2$
Formula: \[\sum_{i=1}^{n} x_i\]

Smart normalization handles split expressions:

• $4.99 \rightarrow $14.99 → $4.99 \rightarrow 14.99$ ✓
• MathJax loaded automatically when needed

Requirements
