The Chicago Design System (CDS) is our public identity for the City of Chicago.

The design system is made up of elements like our public mark, our civic typeface, colors, secondary type families, and internet widgets.

The Chicago Design System theme was developed in pro bono partnership with Ogilvy, and type designer Patric King of House of Pretty. Typefaces Big Shoulders, Saira, Roboto, and Lora are hosted on Google fonts.
