Frequently Asked Questions

What is the difference between Markdown and HTML?

Both describe how text should be formatted, but HTML uses explicit tags and can express almost any layout, while Markdown offers a small set of shorthand characters covering the common cases: headings, bold, italics, lists, links and code. Markdown is normally converted into HTML behind the scenes, and most versions let you drop raw HTML in when you need something Markdown cannot express.

Is Markdown a programming language?

No. It gives no instructions and performs no calculations. It is a markup syntax: a way of annotating plain text to say which parts are headings, emphasis, lists or links.

Why are there so many versions of Markdown?

The original 2004 description left a number of cases ambiguous, so different projects filled the gaps in different ways and added their own extras, such as tables and task lists. CommonMark is a later effort to pin the core rules down precisely, and GitHub Flavored Markdown is a widely used extension of it.
