Quick Answer

Introduction
Markdown to lekki język znaczników stworzony przez Johna Grubera w 2004, który używa formatowania plain text do produkcji ustrukturyzowanych dokumentów. Celem jest czytelność —tekst źródłowy Markdown powinien wyglądać jak to co reprezentuje, bez wizualnego clutter tagów HTML. Markdown jest standardem dla README na GitHub, dokumentacji, blogpostów i aplikacji notatkowych jak Obsidian i Notion.
Step by Step
-
Learn the basic syntax
Headings: # H1, ## H2, ### H3. Bold: **text**. Italic: *text*. Lists: - item or 1. item. Links: [text](url). Images: . Code: `inline` or ```block```. Blockquotes: > quote. Horizontal rule: ---.
-
Understand the philosophy
Markdown is designed to be readable as plain text. The source should look close to the final rendered output — **bold** looks like bold, # Heading looks like a heading. This contrasts with HTML, where <strong>bold</strong> and <h1>Heading</h1> are visually cluttered.
-
Learn the variants
Original Markdown (Gruber's spec) is minimal. CommonMark is a standardized, well-specified version. GitHub Flavored Markdown (GFM) adds tables, strikethrough, task lists, and autolinks. MDX lets you embed React components in Markdown. Most tools support GFM.
-
Convert Markdown to HTML
Markdown is converted to HTML for web publishing. # Hello becomes <h1>Hello</h1>, **bold** becomes <strong>bold</strong>. Static site generators (Astro, Hugo, Jekyll) convert Markdown at build time. Use our Markdown to HTML Converter for instant conversion.
Examples
Heading and paragraph
Input: # Title
A paragraph.
Output: <h1>Title</h1>
<p>A paragraph.</p>
Bold and italic
Input: **bold** and *italic*
Output: <strong>bold</strong> and <em>italic</em>
Link and image
Input: [text](https://example.com) and 
Output: <a href="https://example.com">text</a> and <img src="image.png" alt="alt">
Common Problems
- Line breaks —a single newline in Markdown does not create a line break in HTML. Use two spaces at the end of a line, or two newlines for a paragraph break.
- Nested lists —indentation matters. Use 2 or 4 spaces consistently for nested items; mixing them can break the list structure.
- Raw HTML —most Markdown parsers pass through raw HTML, but some sanitize it. Check your parser's behavior if you embed HTML directly.
- Different flavors —Original Markdown, CommonMark, and GFM have subtle differences. Check which flavor your target platform supports.
Tips
- Use Markdown for writing and documentation —it is much easier to read and write than HTML.
- GitHub Flavored Markdown (GFM) is the most common variant —it adds tables, strikethrough, and task lists.
- Write in Markdown and convert to HTML at build time for blogs and documentation sites.
