About

Foundation is an open-source responsive framework that provides a customizable grid system, a library of UI components (Building Blocks), HTML templates, and JavaScript plugins.

It includes keyboard accessibility, screen-reader support, ARIA attributes, device-adaptive visibility controls, and two types of grids (Flexbox and CSS Grid) to enable advanced layout control.

Radix UI is an open-source component library that provides low-level, unstyled interface primitives for building accessible user interfaces and design systems in web applications.

It includes modular components for common UI patterns such as dialogs, dropdown menus, tooltips, sliders, tabs, and checkboxes, and implements WAI-ARIA accessibility patterns with keyboard navigation and focus management.
