A flat reference of every utility class in the system. Click any class, value, or token to copy it. For the full architecture and live demos see Typography, Color, Spacing, Border, and HTML Layout.

Every chip on this page follows the same convention so the markdown source matches what gets copied:

  • `.class-name` → utility class, copies
  • `var(--token-name)` → CSS variable, copies
  • `#abc123` → hex colour, copies and renders a swatch

Text Size

Two scales sit side by side. The semantic scale is the default — reach for for body and only drop to the granular .font-* classes when you need a precise step on the type ramp.

Use tokens directly

A few things have tokens but no utility classes — apply the token via var(...) directly in CSS.

Concern Tokens
Font weight , , , , , ,
Line height , , , , ,
Letter spacing , , ,
Border radius , , , , ,
Text alignment use raw CSS text-align

Every token name above is still copyable — click to grab for your stylesheet.
