An abstraction called text styles – How to save yourself from a typographic mess

Sharing an understanding of the concept of responsive design is a requirement for designing a functional typographic hierarchy, and thus for creating an effective text styles abstraction. Developers are quite well off by creating the text styles mobile first, and then applying the required adjustments for each breakpoint. Using polyfluid sizing relying in viewport units and linear interpolation, we can create text styles that match the exact sizes defined for selected breakpoints, and are linearly scaled between these breakpoints.
