Overview
A Design System can generally be thought of as a collection of resources for interactive media that promotes brand alignment.
Creating a Component Library
Not only is FAST great for creating individual components, but it also shines when creating libraries or systems of components.
Design Tokens
The FAST Design Token implementation is designed to provide first-class support for Design Tokens and make setting, getting, and using Design Tokens simple.
High Contrast
High contrast mode uses the CSS media feature, forced-colors. When forced-colors is set to active, the user agent will apply a limited color palette to the component.
MatchMedia Stylesheets
FAST exposes a mechanism to attach stylesheets conditionally based on a MatchMedia query.
Localization
FAST provides several mechanisms to apply direction-based styles.
