Good luck finding a catalog in portrait view! I've never seen one myself.
I will keep looking. 🙂
It's to have a better user experience on mobile.
What do you think ?
Can be done to any size – upright, landscape or square. Interactivity though will be limited with PDFs to internal and external hyperlinks.
Maybe InDesign's Publish Online might be worth consdiering.
thank you for your reply
Here's a link to an excellent online video tutorial from Linkedin Learning on creating Publish Online documents (you can 30-days free access).
If you know how to create InDesign documents it's easy to produce these documents with Publish Online that can include multimedia content. But they have to be hosted on Adobe servers.
