For designers

While many programs maintain their own unique brand identities, the Design System offers a common visual style that you can flexibly apply to a range of government digital platforms. Our visual style offers a clean, modern aesthetic that meets high standards of visual accessibility while promoting credibility, trust, and warmth in the design.

We expect many teams will need to customize this guide, but we encourage you to incorporate as much consistency in look, feel, and usability as you can.

As a complement to this visual style guidance, we strongly recommend you use 18F’s Content Guide when writing language for government services.

Design resources

The site contains HTML mockups of common UI components designed to follow the U.S. Web Design System’s visual style guide. To view the specs of each design live on this website (padding, margins, stroke weight, line-height, and so on), use your browser’s developer tools.

All of these designs are also available in various file formats, which are available for download:
