What problem does it solve? Manually styling Markdown content for platforms like WeChat Official Accounts is tedious, since these platforms strip external stylesheets and require inline CSS. This Skill converts Markdown files into fully styled, self-contained HTML documents ready for direct publishing. ## Core Features & Use Cases - Themed HTML Conversion: Renders Markdown with three built-in themes (default, grace, simple) and inlines all CSS using juice for platform compatibility. - Rich Markdown Support: Handles code syntax highlighting, math, PlantUML and Mermaid diagrams, footnotes, GFM alerts, ruby text, tables, and YAML frontmatter metadata. - Image Handling: Downloads remote images, resolves local paths, and reports content images as structured JSON for downstream upload workflows. - Use Case: You wrote a technical article in Markdown with code blocks and diagrams. Run the converter to get a styled HTML file you can paste directly into the WeChat editor without losing formatting. ## Quick Start Convert my article.md file to HTML using the grace theme so I can publish it on WeChat.
