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.
Headless UI is an open-source library of unstyled, fully accessible UI components designed for 
React and 
Vue applications, with close integration with 
Tailwind CSS.
It provides interactive components such as dialogs, menus, listboxes, comboboxes, tabs, switches, and popovers, implements keyboard navigation and 
ARIA accessibility patterns, and supplies only the behavior and accessibility logic so developers can apply any design system, CSS framework, or custom styling.
