Creating code blocks in the Markdown editor

In the Markdown editor, you can use two methods to create fenced code blocks.

  1. Using triple backticks ``` before and after the included code snippet.

To apply a language's specific syntax highlighting, include the language shortcode (see list below) after the first 3 backticks.

For example:

[your code snippet]


  1. Using the Insert codeblock option from the formatting toolbar on the editor

Custom language

If you wish to have a language name unavailable in the list, you can choose the Custom language. In custom language, you can add the desired code block title.

  1. Click Insert codeblock
  2. In the language dropdown, select Custom
  3. Type the desired title and code

Indentation and code blocks

Any text indented at least four spaces will be treated as a code block. This is helpful for more extended code snippets. This code will not be syntax-highlighted but will be shown as plain text.

The following code block is created using indents instead of backticks.

def test():
    logging.error('Test failed')

Code block examples

using System;
namespace HelloWorld
    class Hello 
        static void Main()
