What is this tool for?

CSS variables are a useful technical foundation for consistent websites. Instead of repeating colors, spacing and layout values across stylesheets, central variables can be defined once and reused everywhere.

The generator does not create finished components. It creates a clean token set, which makes it a useful companion to the CSS builder without duplicating it.
