This "Quick Reference" section of the Foundation Elements in the Core Design System provides design specifications covering typography, color, iconography, and spacing. While full documentation is available, this guide highlights the key items designers and developers need to consider when discussing a high-level estimate of effort to implement these foundation elements across platforms.
Typography
The core design system uses the Roboto font family, with Roboto Condensed Medium for specific headings, to create a modern, clean, and versatile appearance across all platforms.
