I'm interested in creating a demo for my course (created in storyline) using storyline. I really like this example: http://articulate.demos.s3.amazonaws.com/HP-Envy-Demo/story.html. But can't find any guidance on how it was created. To my beginner eye, it just looks so different from the courses I've created. How did they get rid of the menu altogether and the navigation at the bottom? How did they create the gallery? Any ideas?
