I'd like to make a project in this format, but I'm not sure where to start. Can anyone explain to me what exactly this is? I can't find anything about a webpage or scroll-through brochure in the express templates of features, but I'm new to this so maybe I just can't find it.
Thanks for reaching out to us. I'd like to inform you that the project you've shared above is a 'webpage' project created on the Creative Cloud Express. The creator used multiple features available inside the webpage project, such as photo grids, slideshows etc.
