Frequently Asked Questions

What templates are available?

The tool provides Light, Dark, and Blue theme templates that include pre-configured color, spacing, font, and border-radius variables. You can also start from scratch with the Custom template.

Can I add custom variables?

Yes, you can add as many custom variables as you need using the Add Variable button. Each variable has a name and value field, and color values automatically get a color picker and preview swatch.

How does the live preview work?

The live preview panel renders a sample UI using your CSS variables in real time. It shows buttons, cards, and color swatches styled with your variables so you can see how your design system looks before exporting.

How do I export the generated CSS?

You can copy the generated CSS to your clipboard with one click, or download it as a .css file. The output is a standard :root block with all your custom properties ready to use in any project.

What types of variables can I create?

You can create any CSS custom property including colors, spacing values, font families, font sizes, border radii, and more. Color values are automatically detected and provide a color picker for easy selection.
