Share samples of code with fenced code blocks and enabling syntax highlighting.

Fenced code blocks

You can create fenced code blocks by placing triple backticks ``` before and after the code block. We recommend placing a blank line before and after code blocks to make the raw formatting easier to read.

function test() {
  console.log("notice the blank line before this function?");

Rendered fenced code block

Tip: To preserve your formatting within a list, make sure to indent non-fenced code blocks by eight spaces.

Syntax highlighting

You can add an optional language identifier to enable syntax highlighting in your fenced code block.

For example, to syntax highlight Ruby code:

require 'redcarpet'
markdown ="Hello World!")
puts markdown.to_html

We use Linguist to perform language detection and syntax highlighting. You can find out which keywords are valid in the languages YAML file.
