show and highlight differences in text

Hi heroes! I am trying to show coding differences between user input and the correct code. Is there a way to do this? I am using references to port the user's input to the field next to the correct code but I'd love to be able to highlight the differences. Is that possible?  Here is the draft: https://360.articulate.com/review/content/bc691792-ce90-4b58-81f2-fc79e2fe86d6/review

Thank you!
