Markdown ↔ HTML Converter

Cheat Sheet (Common Markdown)

• #-###### headings, **bold**, *italic*, ~~del~~, `code`, fenced blocks with ```.
• Lists: - or * for bullets; 1. for ordered. Links: [text](url). Images: ![alt](src).
• HTML → MD covers: headings, paragraphs, em/strong, code/pre, a, img, ul/ol/li, and blockquotes.
• Escaping: inline code renders literally; fenced code blocks are not syntax-highlighted (no external libs).
