Markdown’s syntax is simple and intuitive, using plain text and special characters to indicate various formatting elements such as headings, lists, links, and more. Markdown has gained immense popularity for several reasons:
There is no official standard for Markdown syntax, and different implementations may have different features or behaviors. These variations are called flavors of Markdown. Some of the most common flavors of Markdown are:
There are many other flavors of Markdown, such as MDX, MDsveX, Markdoc, Remarkable, etc. Each flavor may have its own syntax rules and options.
Markdown and HTML are both markup languages that can be used to create formatted text documents. However, they have some differences in terms of syntax, features, and usage:
Syntax: Markdown uses a simple and intuitive syntax that consists of symbols and characters, such as
# for headings,
* for emphasis,
[ ] for links, etc. HTML uses a more complex and verbose syntax that consists of tags and attributes, such as
<h1> for headings,
<em> for emphasis,
<a> for links, etc.
Usage: Markdown is mainly used for writing plain text content that can be easily read and edited by humans. It is often used for creating readme files, blog posts, documentation, notes, etc. HTML is mainly used for publishing structured content that can be rendered by browsers. It is often used for creating web pages, applications, newsletters, etc.
Here is an original example of Markdown and its equivalent HTML:
# Heading 1 ## Heading 2 This is a paragraph with some **bold text** and *italic text*. - Item 1 - Item 2 - Item 3 [Visit byby.dev](https://byby.dev)
<h1>Heading 1</h1> <h2>Heading 2</h2> <p>This is a paragraph with some <strong>bold text</strong> and <em>italic text</em>.</p> <ul> <li>Item 1</li> <li>Item 2</li> <li>Item 3</li> </ul> <p><a href="https://byby.dev">Visit byby.dev</a></p>
