# Markdown69 > Markdown69 is a complete Markdown reference: every rule next to its rendered result, plus a free editor with live preview on the same page. No sign-up, nothing to install – your text never leaves your browser. Markdown69 is a free, ad-free reference for Markdown, the plain-text formatting syntax created by John Gruber in 2004 and standardised for GitHub as GitHub Flavored Markdown (GFM). Every rule on the page is shown beside the result it produces. The site also runs a Markdown editor in the browser: the text is rendered locally by the page's own JavaScript and is never uploaded anywhere. ## Pages - [Markdown Cheat Sheet & Online Editor](https://markdown69.com/): the full cheat sheet, 16 sections, each rule next to its rendered output. - [Online Markdown Editor with Live Preview](https://markdown69.com/#editor): write Markdown on the left, see the formatted result on the right. Full-screen mode, synchronised scrolling, and export to .md, .txt or PDF. ## Cheat sheet sections - [Headings](https://markdown69.com/#headings) - [Emphasis](https://markdown69.com/#emphasis) - [Blockquotes](https://markdown69.com/#blockquotes) - [Lists](https://markdown69.com/#lists) - [Task lists](https://markdown69.com/#task-lists) - [Links](https://markdown69.com/#links) - [Images](https://markdown69.com/#images) - [Code](https://markdown69.com/#code) - [Tables](https://markdown69.com/#tables) - [Horizontal rule](https://markdown69.com/#horizontal-rule) - [Line breaks](https://markdown69.com/#line-breaks) - [Escaping characters](https://markdown69.com/#escaping-characters) - [Footnotes](https://markdown69.com/#footnotes) - [Emoji](https://markdown69.com/#emoji) - [Inline HTML](https://markdown69.com/#inline-html) - [Embedding videos](https://markdown69.com/#embedding-videos) ## Common questions - **How do I write a heading in Markdown?** Put one to six `#` characters and a space before the text. `# Title` is the largest heading, `###### Title` the smallest. The top two levels also accept an underline style: `=====` under a line makes it a level-1 heading, `-----` a level-2 one. - **How do I make text bold or italic?** Wrap it in two markers for bold and one for italic: `**bold**` or `__bold__`, `*italic*` or `_italic_`. Three markers give both: `***bold italic***`. GitHub Flavored Markdown adds `~~strikethrough~~`. - **How do I create a table in Markdown?** Separate cells with `|` and put a row of dashes under the header: `| A | B |` then `| --- | --- |`. A colon in the dash row sets alignment: `:---` left, `:---:` centre, `---:` right. Tables are a GFM extension, not part of the original Markdown. - **How do I add a link or an image?** A link is `[text](https://example.com)`; an image is the same with a leading exclamation mark, `![alt text](image.png)`. Both accept an optional title in quotes after the URL. - **How do I write a code block?** Indent by four spaces, or fence the block between lines of three backticks. Adding a language after the opening fence (` ```python `) turns on syntax highlighting on GitHub and most other renderers. For code inside a sentence, wrap it in single backticks. - **Does Markdown support underlined text?** No. Markdown has no underline syntax, because underlined text on the web reads as a link. Renderers that allow inline HTML accept `text` instead. - **How do I make a line break without a new paragraph?** End the line with two spaces, or with a backslash. A blank line starts a new paragraph instead. - **What is the difference between Markdown and GitHub Flavored Markdown?** GFM is a superset: it keeps every original rule and adds tables, task lists, strikethrough, autolinks and fenced code blocks. Anything written in original Markdown is valid GFM. ## Translations This page exists in 13 languages, English at the root and the rest under a language prefix: - [中文](https://markdown69.com/zh/) - [Español](https://markdown69.com/es/) - [Português](https://markdown69.com/pt/) - [Bahasa Indonesia](https://markdown69.com/id/) - [Français](https://markdown69.com/fr/) - [日本語](https://markdown69.com/ja/) - [Русский](https://markdown69.com/ru/) - [Deutsch](https://markdown69.com/de/) - [한국어](https://markdown69.com/ko/) - [Italiano](https://markdown69.com/it/) - [हिन्दी](https://markdown69.com/hi/) - [Türkçe](https://markdown69.com/tr/)
