Markdown Table Syntax
Separate table columns with |. Use colons in the separator row to align their contents.

How to use this Markdown cheat sheet
- Search or browse a syntax category.
- Copy an example into the live preview.
- Check the rendered result before using it.
Example
# Title
**bold** / *italic*Use the source and result columns together to learn which punctuation produces each effect. The example below shows a bold word and its HTML equivalent. Copy an example into the previewer when you want to edit it, then export Markdown or sanitized HTML. Use short paragraphs, headings, lists, and code examples to keep documentation readable.
CommonMark describes core Markdown while GFM adds tables, task lists, and strikethrough. This reference also renders shared footnotes and alerts, but labels GitHub specific examples separately when they are source only. Raw HTML support varies by destination. Printing includes every example even when filters are active, so check the browser's print preview before saving the sheet as PDF.

HTML: <strong>Ada</strong>
Frequently Asked Questions
What is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It uses plain text formatting syntax to create HTML: #headings, **bold**, *italic*, [links], `code`, and more. It's used in README files, GitHub, Reddit, Slack, and many documentation systems.
What is the difference between CommonMark and GFM?
GFM extends CommonMark with tables, task lists, strikethrough and automatic links. Shared footnotes and alerts also render here. Start a fenced block with three backticks plus its language and close with three backticks. Language classes are preserved without syntax coloring. Mentions, issue links, commit links and Mermaid require destination support.
How do I escape special Markdown characters?
Use a backslash before the character: \* for *, \_ for _, \` for `, \# for #, \[ for [, etc. This prevents Markdown from interpreting them as formatting syntax.
How do I make a Markdown table?
Separate cells with pipes and add a separator row such as | --- | --- |. Use :---, :---: or ---: in that row for left, center or right alignment.
How do I copy, export, or print examples?
Use Copy beside an example for its original Markdown, including indentation. Paste it into the previewer to edit or export .md and sanitized .html. Print / Save as PDF opens the browser dialog. Printing includes every example regardless of active search or category filters; inspect the print preview before saving.
