I built this experience in Articulate Storyline 360, using click-to-reveal interactions for each musical era. I set up each section with layered audio triggers, so learners could listen to short samples while reading the historical context.
To enhance the learner experience, I used timeline animations to create smooth transitions between eras, and added custom tick mark indicators that update when each section is visited. Completion logic was added via true/false variables, ensuring learners progress only after exploring all content.
