In one of my recent blog post, I did a design review of all options available and how the text is represented for the user. It covers all possible options to present content on a communication page.
While we have now great capabilities to design the content I found still some gaps in the user experience and things that would be great to see in the future.
Some of that thing can be accomplished through Responsive Typography and or properly designed layout of pages that not only have a great design but also follow common user experience and design patterns.
