Code Highlighting

Whisper uses Hugo’s in-built code highlighting with a github style code highlighting theme. https://gohugo.io/content-management/syntax-highlighting/

You can insert code snippets in any markdown file by using standard code fences syntax ie:

function myFunction() {
  var x = document.getElementById('myDIV');
  if (x.style.display === 'none') {
    x.style.display = 'block';
  } else {
    x.style.display = 'none';
