JavaScript

Prism.js is a wonderful little javascript library for highlighting code at runtime. It support various themes + a ton of languages and is really easy to implement in Ghost.

#include <stdio.h>
 
int main()
{
  printf("Hello world\n");
  return 0;
}

Setup

All you have to do is go to prismjs.com and build a version that suits you and upload the css and javascript files into your theme assets folder. And finally add them to the code injection settings in Ghost.

<!-- Add the css in the header -->
