Hard-coded color values and magic numbers scattered across CSS files make global changes (a rebrand, a dark mode, a spacing adjustment) require finding and updating dozens of individual lines. Custom properties centralize these values so one change propagates everywhere — and enable runtime theming that preprocessor variables cannot.
Find hard-coded color values, spacing values, and font sizes in this CSS file that should be replaced with CSS custom properties.
Extract repeated and meaningful values into CSS custom properties on :root and replace all usages with var() references.
Explain CSS custom properties: how they differ from preprocessor variables, how cascade and inheritance work, and how to use them for theming.
Review stylesheets, component styles, and responsive states related to Use CSS custom properties for design tokens. Flag exact selectors, declarations, or breakpoints that violate the rule in the rendered UI.
