SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

base-joy uses a Joy UI-inspired CSS variables system. Theme tokens become CSS custom properties at runtime, enabling theming without rebuilds.

Core Features & Use Cases

  • Direct themeVars access in code (zIndex, animation) and use in Tailwind or style props.
  • Runtime theming via CSS variables generated from theme definitions.
  • Simple customization by overriding tokens in ThemeProvider.

Quick Start

Use themeVars.vars to access zIndex and animation tokens and apply to components, then override tokens at runtime via ThemeProvider.

Frequently Asked Questions about css-variables

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I apply CSS variables for runtime theming without rebuilding?▼

CSS variables enable runtime theming by storing theme tokens as custom properties. Use a theme object with tokens like zIndex and animation, generate CSS variables via a prepareCssVars utility, and apply them through a ThemeProvider component to style UI without rebuilds.

Can I use CSS variables to theme animation durations and z-index layering?▼

Yes. CSS variables support themeable animation tokens—durations and easings—and z-index layering. Access these via themeVars.vars in your component styles and override them at runtime by customizing tokens in the ThemeProvider.

How do I customize theme tokens at runtime?▼

Override theme tokens by passing custom values to the ThemeProvider component. It generates new CSS variables from your token object, applying them to all scoped components without requiring a rebuild or page refresh.

Can I access theme tokens directly in Tailwind and inline styles?▼

Yes. Theme tokens are accessible via themeVars.vars for direct use in Tailwind classes and style props. This allows component-level styling with consistent, themeable values across your application.

What's the difference between CSS variables theming and traditional theme rebuilds?▼

CSS variables theming applies theme changes at runtime via custom properties, eliminating rebuild cycles. Traditional approaches require recompiling stylesheets; CSS variables update instantly and scale to multiple themes without code changes.

Do I need to restructure my components to use CSS variable theming?▼

No significant restructuring is required. Use themeVars.vars to reference tokens in existing styles, wrap your app with ThemeProvider, and customize tokens as needed. The theme system integrates with standard CSS and component patterns.
