CSC Design System Skills & Best Practices
CS

Proposed CSC Standards

Design foundations

Color, type, and spacing tokens that component rules depend on.

Rules

FND-001RequiredProposed CSC convention

Use the CSC brand blue and brand red tokens

Brand blue is #2A338F. Brand red is #EC1C2D. Action red for white text is #C41222.

Implementation detail

Proposed CSC Standard drawn from the identity guide values already in this system. It is not a claim of a separate approved policy document.

Use var(--primary), var(--brand-red), and var(--red). Do not introduce #00499C or #D72638.

Check: New colors are the documented tokens.

FND-002RequiredProposed CSC convention

Set body text to the Aptos stack at 16px

The font stack is Aptos, Calibri, Roboto, Open Sans. Body size is 16px, which is 12pt.

Implementation detail

Proposed CSC Standard. Aptos, Calibri, and Mirante are not embedded. Roboto and Open Sans are the loaded fallbacks.

Do not import a different display font for product UI. Do not label another font as Mirante.

Check: The computed body font-family starts with Aptos and the size is 16px.

FND-003RecommendedProposed CSC convention

Keep surfaces light

Pages use white and neutral gray with restrained blue and red.

Implementation detail

Proposed CSC Standard matching the current shell.

Do not add a dark theme unless the product has one. This system does not.

Check: The page background is white or the existing gray canvas.
