Horizon is a modern UX framework that enables developers to create responsive, accessible, and consistent user experiences across applications. Horizon provides a unified design system that improves usability and performance. It
supports accessibility standards and ensures a consistent look and feel across the Now Platform.

## Key design principles {#design-an-app__section_lcn_4xg_qhc}

1. Follow ServiceNow's design guidelines for consistency.
2. Use Horizon components such as cards, lists, and Workspaces for a modern experience.
3. Plan for responsive behavior to support multiple devices.
4. Ensure accessibility compliance for all UI elements.

## Best Practices {#design-an-app__section_yfb_hzg_qhc}

Start with user personas to define workflows and UI needs. Leverage Horizon's reusable components to reduce development time and maintain upgrade safety. Avoid unnecessary custom styling to preserve governance.
