How to use CSS Variables Generator

Enter your color palette and spacing scale, and the tool converts them into a :root block of CSS custom properties ready to drop into your stylesheet.

Frequently asked questions

Can I use these variables with a dark mode toggle?

Yes. Wrap a second block of the same variable names under a [data-theme="dark"] or prefers-color-scheme selector to swap values per theme.

Can I paste this directly into my existing stylesheet?

Yes. The output is plain CSS — add it to any stylesheet or CSS-in-JS setup that accepts raw CSS.

Will this override my existing styles?

Only where selectors or property names match. Check specificity and load order if you see conflicts with existing rules.
