Frequently Asked Questions

What is Markdown?

Markdown is a lightweight markup language used to format text. It uses simple plain-text syntax (like # for headings, * for lists) that converts to valid HTML. It's widely used in README files, forums, and documentation.

What syntax is supported?

This previewer supports standard Markdown syntax: # Headings, **Bold**, *Italic*, - Lists, 1. Ordered Lists, [Links](url), ![Images](url), `Code`, and > Blockquotes.

Can I use HTML inside Markdown?

Yes, standard Markdown allows raw HTML tags (like <div> or <span>) to be mixed with Markdown syntax for advanced formatting.

Background & Theory

Markdown works by mapping special characters to HTML tags. **Common Mappings:** - `# Text` → `<h1>Text</h1>` - `**Text**` → `<strong>Text</strong>` - `[Link](url)` → `<a href="url">Link</a>` - `> Quote` → `<blockquote>Quote</blockquote>` **Why Use Markdown?** 1. **Readability:** The raw code looks almost like the final result. 2. **Portability:** It's just plain text. It opens in any editor. 3. **Efficiency:** Typing `#` is faster than typing `<h1></h1>`. 4. **Focus:** Writers can focus on content rather than styling tags. **Flavors:** While standard Markdown covers the basics, "flavors" like GFM (GitHub Flavored Markdown) add features like tables, task lists, and strikethrough, which have become widely expected by users.

History

Markdown was created in 2004 by John Gruber with substantial contributions from Aaron Swartz. Gruber's goal was to create a writing format that was easy to read and write in its raw form, while being convertible to structurally valid XHTML (or HTML). He wanted to avoid the heavy, cluttered syntax of HTML tags for writers. The inspiration came from existing conventions for marking up plain text in email (like using *asterisks* for emphasis). Markdown quickly gained popularity in the tech community. Sites like GitHub (GitHub Flavored Markdown), Stack Overflow, and Reddit adopted it for user content. It became the standard for documentation (README files) and static site generators (Jekyll, Hugo). In 2014, the "CommonMark" specification was released to standardize Markdown syntax across different parsers, ensuring consistency.
