Frontend Design Tokens

Frontend Design Tokens

When writing CSS/SCSS in the Sculptor frontend, use design tokens instead of hardcoded values.

Where to Find Tokens

Radix Built-in Tokens (spacing, font sizes, radius, colors, font weights)

Read the source of truth directly:

sculptor/frontend/node_modules/@radix-ui/themes/tokens/base.css

This file contains all Radix CSS variables including:

• --space-1 through --space-9 (spacing)
• --font-size-1 through --font-size-9 (typography)
• --font-weight-light, --font-weight-regular, --font-weight-medium, --font-weight-bold
• --radius-1 through --radius-6, --radius-full (border radius)

For color tokens, read the individual color files:

sculptor/frontend/node_modules/@radix-ui/themes/tokens/colors/*.css

These provide 12-step scales (e.g., --gray-1 through --gray-12, --accent-1 through --accent-12).

These are all loaded via @radix-ui/themes/styles.css which is imported in Main.tsx.

Custom Tokens (animation, z-index, shadows, semantic colors)

Read our custom token definitions:

sculptor/frontend/src/styles/tokens.css

This defines tokens for things Radix does not provide.

Radix Overrides

Global overrides to Radix component styles live in:

sculptor/frontend/src/styles/radix-overrides.css

Global Styles

Brand colors, utility classes, and theming live in:

sculptor/frontend/src/index.css

Rules

1. Never hardcode values that have a corresponding token or Radix variable
2. Prefer Radix component props (e.g., <Flex gap="2">) over var() when possible
3. Use var() in SCSS modules for values that can't be expressed through props
4. No hex or rgb colors in SCSS files -- use Radix color variables or semantic tokens

Examples

/* Bad */
.card {
  padding: 16px;
  font-size: 14px;
  border-radius: 8px;
  transition: opacity 0.2s ease;
  color: #3d63dd;
}

/* Good */
.card {
  padding: var(--space-4);
  font-size: var(--font-size-2);
  border-radius: var(--radius-4);
  transition: opacity var(--duration-normal) var(--ease-default);
  color: var(--accent-9);
}

Audit Script

Run to find style violations:

cd "sculptor/frontend" && npm run lint:styles
