Understanding Markdown Editor: A Complete Guide
Markdown is a lightweight markup language that lets you write formatted text using a plain-text editor. Created by John Gruber in 2004, Markdown is now one of the world's most popular markup languages, used for documentation (GitHub, GitLab), blogging, note-taking, and content management.
Our Markdown Editor provides a professional writing environment with real-time preview, making it easy to see exactly how your formatted document will look. The split-pane interface shows your Markdown source on the left and rendered HTML on the right, updating instantly as you type.
Supporting GitHub Flavored Markdown (GFM), the editor handles advanced features like tables, task lists, syntax-highlighted code blocks, strikethrough text, and automatic linking. Whether you're writing README files, technical documentation, blog posts, or academic notes, this editor provides a distraction-free environment optimized for Markdown content creation.

Troubleshooting Common Issues
Issue: Preview not updating when I type
Solution: Check if JavaScript is enabled in your browser. The live preview requires JavaScript to process Markdown in real-time. Try refreshing the page if the issue persists.
Issue: Tables don't render correctly
Solution: Ensure your table syntax follows GitHub Flavored Markdown format. Use pipe characters (|) for columns and hyphens (---) for the header separator row. Alignment colons (:) are optional.
Issue: Code blocks not showing syntax highlighting
Solution: Make sure to specify the language after the opening backticks (e.g., ```javascript). Without a language tag, code will render as plain text without highlighting.
