Foundation
Foundation is a responsive front-end framework developed by ZURB for building websites and web applications with a mobile-first approach. It provides a grid system, UI components, and JavaScript plugins to create responsive, accessible, and customizable interfaces quickly. It is often used for prototyping and production-ready projects across various industries.
Developers should learn Foundation when they need a flexible, semantic framework for responsive web design that emphasizes customization and accessibility, such as in enterprise applications, marketing sites, or complex web apps. It is particularly useful for projects requiring a mobile-first strategy, extensive theming options, or integration with other tools like Sass and JavaScript libraries, as it offers modular components and a robust grid system.
