About CSS Variable Generator

CSS custom properties (variables) allow you to define reusable values in a central location using the :root selector and reference them with var(--name). This generator helps you build three types of design token sets: color palettes with semantic names, spacing scales based on a base unit and multiplier, and typographic scales using classic musical ratios like the Perfect Fourth (1.333) or the Golden Ratio (1.618).
