Store colours, spacing and type values in one place.

Intermediate 12 min read Lesson 2 of 300 Challenge included

What you will be able to do

Use $name for Sass variables.
Group tokens by role.
Use maps for spacing and type scales.
Use CSS variables for runtime themes.

In plain English

Variables make design decisions reusable. Group them by role, not by value, and prefer maps for scales. CSS custom properties are still the right tool for runtime theming.
