Semantic CSS with New UI

Crafted with care. Styled for impact.

New UI is a modern, semantic UI framework for building beautiful, accessible sites and apps. It provides the core design foundations you need—including colors, typography, spacing, sizing, layouts, and effects.

Designed to grow with you from your first launch to millions of users, it is thoughtfully made for makers, small teams, and anyone who values functional, scalable, and timeless design.

Core Principles

• Built to scale — Core building blocks for modern interfaces that grow with your needs.
• Themes that adapt — Customizable default themes with cold and warm variants to match your brand.
• Framework agnostic — Works seamlessly with React, Vue, Svelte, or any framework you choose.
• Accessibility first — WCAG-compliant with built-in keyboard navigation and focus management.
