What is CSS Variables Generator?

Build a :root custom-property block for your palette. Configure a prefix, include alpha channel variants, and optionally add a dark-mode override block.

Frequently asked questions

+What prefix should I use?

Common choices: --color-, --brand-, or your design-system prefix (e.g. --ds-color-).

+Does it include dark mode?

Optionally — toggle 'include dark mode' and the tool outputs a [data-theme='dark'] block with inverted lightness.

+Can I use the variables with Tailwind?

Yes — reference them via Tailwind's arbitrary value syntax or as color tokens in tailwind.config.
