This brings the popular highlight.js library to CKEditor.


  • Code highlighting in your text editor.
  • Supports various languages (e.g. PHP, JavaScript, etc.).
  • Supports various themes.


Well, there are dedicated code blocks in the marketplace, but it kinds of gets you out the flow of writing technical documentation if you have to quit the editor to add a new 'code' block.
