Frequently Asked Questions
How do I write Markdown with live preview?
Type Markdown syntax in the left pane of an editor and see the rendered HTML instantly in the right pane. The editor re-renders on each keystroke using a Markdown parser (like marked or markdown-it), so you always see what the final output looks like.
What is GitHub Flavored Markdown?
GitHub Flavored Markdown (GFM) is a superset of CommonMark that adds tables, task lists (- [ ] syntax), strikethrough (~~text~~), fenced code blocks with language tags, and autolinks. It's the format used in GitHub READMEs, issues, and pull requests.
How do I add syntax highlighting in Markdown?
Use a fenced code block with a language identifier: ```javascript on the opening fence. Editors that support syntax highlighting apply a library like Prism.js or highlight.js to colorize the code in the preview. The identifier tells the library which grammar rules to apply.
How do I insert a table in Markdown?
Use pipe characters and hyphens. A basic table: | Header 1 | Header 2 | on line 1, | --- | --- | on line 2 for the separator, then | Cell 1 | Cell 2 | for data rows. GFM also supports column alignment: :--- for left, ---: for right, :---: for center.
