Using Markdown in Replit

Markdown is a lightweight markup language with plain text formatting syntax. It is designed to be easy to read and write, and it converts to valid HTML. Some use cases of Markdown include documentation, project descriptions, text formatting in social media posts, and more. In this tutorial, all major topics including advanced markdown rules will be covered.

Basic syntax

Basic syntax includes the foundations of markdown usage such as headers, paragraphs, text formatting, and more.

Bold & italic text

To make text bold in Markdown, surround it with two asterisks on each side: **bold**. To make text italic in Markdown, surround it with either one asterisk on each side *italic* or with an underscore on each side: _italic_

Inline code

You can denote inline code in Markdown by surrounding it with backtick quotes (`<insert code here>`). Inline code corresponds to a highlighted area in a sentence or paragraph, not an entire block of code.

Strikethrough text

To strikethrough text in Markdown, surround it with two tildes on each side: ~~strikethrough~~. This can be used to denote edits or deletions.


To create a heading in Markdown, start a new line and put up to six hash symbols followed by a space in front of the header's text ## header. Using a single hash symbol for a heading specifies the largest header and using six hashes renders the smallest header.

Super small header example

The corresponding Markdown code used to render the above example is included below.

###### Super small header example


To create a new paragraph, simply add two line breaks after a series of plaintext sentences.

This paragraph is separated from the above one.

I am paragraph number one.

I am paragraph number two, completely separated from paragraph one.


You can create unordered lists using asterisks *, pluses +, or hyphens -:

  • Item 1
  • Item 2
  • Item 3
- Item 1
- Item 2
- Item 3

You can create ordered lists using numbers followed by periods:

  1. Item 1
  2. Item 2
  3. Item 3
1. Item 1
2. Item 2
3. Item 3


You can use blockquotes to denote quoted text. To create a blockquote, start a line with >:

This is quoted text

> This is quoted text

Line breaks & thematic breaks

Occasionally, you may want to add a breakline within a paragraph. To do this, you can add two spaces at the end of a sentence and hit the enter key to move on to the next line. Alternatively, you can use the HTML tag <br/> to make the breakline for you.

I am a broken

I am a broken<br/>

Code blocks

In many cases, you might have to show a large amount of code within a Markdown document. In the case of technical documentation, code blocks are present almost everywhere. You can surround your code by three backticks ```.

def printHello():
print("Hello World")

print("Look what I'm printing:")

To add syntax highlighting, type in three backticks and then the programming language ```python.

def printHello():
print("Hello World")

print("Look what I'm printing:")


You can also embed links, images, and videos within Markdown documents.

To embed a link in Markdown, surround the link text in square brackets [link] followed by the link URL surrounded in parentheses [link]( You can now put a link almost anywhere in your markdown document.

To embed an image in markdown, start with an exclamation point and put the description of the image in square brackets, followed by the image URL surrounded in parentheses ![a picture of a cute cat](

Videos can be embedded easily in most Markdown environments as well. Using default HTML tags, you can link to and embed a video file in your Markdown document.


Iframes & inline HTML

Markdown supports the usage of raw HTML code, so this means you can embed inline frames, use special HTML elements, and more. The Repl below is an inline frame, injected into this markdown document with raw HTML.

Advanced methods

Some advanced Markdown techniques include tables, extended formatting, and more.


Tables display an organized grid of data in rows and columns. Use the vertical line symbol | and hyphens - to construct a table in markdown.

The table above is rendered by the Markdown code below. Using spaces to make the text look clean is optional but recommended.

| name  | age | location  |
| ----- | --- | --------- |
| ben | 25 | New York |
| jane | 37 | Australia |
| rob | 21 | Brazil |
| sarah | 43 | France |

Collapsable details

Collapsing large blocks of text can make your Markdown much easier to digest and navigate.

Small text

Markdown allows the rendering of super small text with the HTML sup (superscript) and sub (subscript) tags. Simply surround your text with the <sup> and <sub> tags to render it super tiny.

<sup><sub>I am so tiny and cute!</sub></sup>

Markdown comments

You can use HTML comments in your Markdown documents or use Markdown syntax to do so as well. Comments do not get rendered in the Markdown output.

<!--html comment does not get rendered-->

Wrap text around images

You can wrap paragraph text around an image that is aligned to the right. Place your image first and then the following paragraph will wrap itself around the image.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed euismod justo eget justo sagittis mattis. Vivamus sollicitudin eget diam ac ultricies. Sed est eros, tempus at justo semper, porttitor blandit est. Integer quis ornare tellus. Nulla facilisi. Nunc eleifend lacus sapien, in tempus augue ultrices quis. Mauris sit amet interdum nisl. Aenean eu fringilla nisi, et lobortis urna. Duis ut tortor quam. Sed rhoncus rutrum dui, placerat facilisis libero consequat commodo. Maecenas varius ligula vel leo bibendum, a feugiat odio mollis.

Markdown on Replit

Markdown on Replit includes some features that are not native to Markdown such as displaying third-party embeds, modified file routing for images/links, and more.

Draw files

Creating a file that ends with .draw in Replit gives you your own Excalidraw whiteboard.

By using the same format to display an image in Markdown, you can display the draw file's contents in your Markdown file.

In Replit's Markdown environment, links work normally but also enable you to link to other Markdown files. Simply use a link and set its destination URL with the file path of another file.

Third-party embeds

Replit currently allows YouTube videos, Loom videos, and Figma prototypes to be embedded in Markdown documents. The syntax for this is similar to embedding an image in Markdown.


Workspace vs. Social Markdown

Markdown in the Workspace is very different than the Markdown you would use on Replit's Community or Bounties. Some of the main differences include:

Essential Syntax
Inline HTML
Videos / Iframes
Third-party embeds
Strikethrough Text
