Sharepoint suitable for a training site?

Theoretically, you can use the same general approach using a site built using modern pages,, which will render fine on mobile devices. It will be better once more page layouts are available. That said, even without a responsive layout, this approach works on tablets. It doesn't render as well on a smaller phone. You need to consider how you users will need the help information-what are the practical use cases. In places where we have used this approach, the majority of users are accessing SharePoint help from their desks. It works on mobile when they are mobile, but that hasn't been the primary use case. I am currently working on a solution that is fully responsive and it's a lot harder to set up and maintain, but it looks great on mobile devices. I just wonder how often it will be "consumed " that way.
