One aspect of this static site that was looking bland was the code snippets first presented in Customizing This Site. Originally, these snippets were presented as black text on a grey background. To improve the visual appearance of code blocks, I decided to add code syntax highlighting with Nord.

Jekyll supports SASS to compile CSS by default. Thankfully, Nord exports its syntax coloring as SASS variables already. Jekyll also supports syntax highlighting via rouge. Rouge is a ruby gem that is capable of parsing many different languages and adding syntax highlighting to them. The resulting HTML from Rouge uses the .highlight class to represent the formatted code.

In order to apply the Nord syntax highlighting to the Rouge output, I created a SASS file that maps the styles to the Nord colors. The mapping file can be found here. The result is the syntax highlighting you see throughout this site!

Below are some examples of the results of syntax highlighting. These snippets (and more) can be found here.


/* Hello World in C, Ansi-style */

#include <stdio.h>
#include <stdlib.h>

int main(void)
  puts("Hello World!");
  return EXIT_SUCCESS;


// Hello World in ISO C++

#include <iostream>

int main()
    std::cout << "Hello World!" << std::endl;


// Hello world in Go

package main
import "fmt"
func main() {
 fmt.Printf("Hello World\n")


// Hello World in Java

class HelloWorld {
  static public void main( String args[] ) {
    System.out.println( "Hello World!" );


; Hello world in LLVM Assembly

@.str = internal constant [14 x i8] c"hello, world\0A\00"

declare i32 @printf(i8*, ...)

define i32 @main(i32 %argc, i8** %argv) nounwind {
    %tmp1 = getelementptr [14 x i8]* @.str, i32 0, i32 0
    %tmp2 = call i32 (i8*, ...)* @printf( i8* %tmp1 ) nounwind
    ret i32 0

Python 3

# Hello world in Python 3 (aka Python 3000)

print("Hello World")


;; Hello world in Racket

#lang racket/base
"Hello, World!"


# Hello World in Ruby

puts "Hello World!"

Shell Script

# Hello world for the Unix shells (sh, ksh, csh, zsh, bash, fish, xonsh, ...)

echo Hello World
