Users need to see the sample code but it's boring

It can be hard to make code exciting. But I think making things look good and adding some interaction could go a long way.

Many common code text editors like VS Code or your favorite coding IDE offer syntax highlighting. Some of these editors support the ability to not only copy the code but to copy the code with the syntax highlighting (https://code.visualstudio.com/updates/v1_10#_copy-with-syntax-highlighting). Just paste and keep source formatting. This would help immensely as you develop because it will allow you to use the new Storyline auto-scrolling text box (updated Aug 2021 https://articulate.com/support/article/Storyline-360-Text-Autofit-Improvements) for longer code examples but it will also save you from taking hundreds of un-editable screenshots.

A few other options could be seen from how sites like freecodecamp have approached some coding interactions where you read then watch then do. Perhaps some of your projects could have some fill-in-the-blanks or some custom cloze exercises that lead into an animation or results video on another slide.
