Responsive Text and Responsive Margins

[prabu-ssb]

Is your feature request related to a problem? Please describe.
Yes, the current design system is well suited for browser pages on PC-s. But when it comes to mobile devices, and specificaly to interactive applications, the font sizes of the text elements do not scale proportionally to the limited real estate on a the mobile device screen

Describe the solution you'd like
font-sizes and vertical margins scale proportionally according to device width (ref: responsive type setting)

Describe why this is useful for SSB
As we are implementing more and more functionality that are not just pages, but are more "app-like" (especially surveys), it is important that the typesetting we use is optimal for the device on which they are deployed.
