Markdown Viewer Pro 作者： Soul in Silicon

✨ Why Markdown Viewer Pro?

Most browsers show Markdown files as raw, unformatted text. Markdown Viewer Pro transforms them into polished, readable documents — with zero configuration required. Whether you're reviewing a project README, reading documentation, or writing notes, your files look exactly as intended.



🚀 Key Features

Beautiful Rendering

• GitHub-Flavored Markdown — headings, bold/italic, tables, task lists, strikethrough, blockquotes, and more rendered flawlessly
• Syntax-highlighted code blocks — 180+ languages powered by highlight.js with GitHub's signature colour themes
• Smart typography — curly quotes, em-dashes, and ellipses automatically applied

Dark & Light Themes

• Toggle between light and dark mode with a single click — or press D
• GitHub-accurate colour palettes for both themes, including syntax highlighting
• Your preference is remembered across sessions

Navigation & Reading

• Auto-generated Table of Contents — jump to any section instantly, toggle with T
• Reading progress bar — always know how far through a document you are
• Heading anchor links — hover any heading to copy a direct link
• Smooth scroll to sections from the TOC

Developer Friendly

• Copy the raw Markdown source in one click
• Per-block code copy button on every code block (appears on hover)
• External links automatically open in a new tab
• Works on local files (file://) and web-hosted .md URLs

Fully Customisable

• Font size controls — A− and A+ buttons to find your perfect reading size
• Line width — choose narrow, normal, wide, or full-width layouts
• Settings panel — all preferences accessible from the toolbar icon
• Everything persisted via browser storage — your setup survives restarts

Print Ready

• Toolbar, TOC, and buttons are automatically hidden when printing
