Strategy Guide for CSS Custom Properties
summary
Claims: global design tokens tend to be static (a 90% rule), local component values tend to be dynamic; prefer Sass for static globals and CSS custom properties for locally dynamic values. Tools shown: Sass interpolation, runtime custom properties, document.documentElement.style.setProperty, and postcss-variables to emit static fallbacks. Built demos: responsive button sizes using one property, a runtime modular-scale generator (works but is better computed at design time), and an organizational pattern called the logic fold. Core rule emphasized: change the value not the variable.
