Frequently Asked Questions
What is GitHub Flavored Markdown (GFM)?
GFM extends standard Markdown with tables, task lists (checkboxes), strikethrough, auto-linking, and fenced code blocks. It's the format used in GitHub READMEs, issues, and pull requests.
Can I preview Markdown tables?
Yes. Use pipe characters (|) to create table columns and hyphens (-) for the header separator. The preview renders them as formatted HTML tables in real time.
Does this support code syntax highlighting?
Yes. Use fenced code blocks with a language identifier (e.g., ```python) to get syntax-highlighted code in the preview.
