Foundation Sites is a front-end framework for developing responsive websites. Foundation offers various components such as responsive grids, buttons, navigation menus, forms, and typography styles that are easy to customize. It also includes powerful plugins like an image slider, modal dialogs, and an equalizer component that makes it easy to ensure all elements in a row are the same height. Foundation's Sass-powered framework makes it easy to change the look and feel of your website by customizing the variables. Foundation Sites is an excellent choice for building a custom web design system with modular components, ensuring consistency and saving time.

JSS is a powerful and flexible JavaScript library for styling your applications. It provides a way to write CSS styles in JavaScript, allowing you to create dynamic and reusable stylesheets. With JSS, you can define styles as JavaScript objects or use CSS syntax with the help of a CSS-in-JS compiler.

Foundation-Sites is a popular front-end framework that has been around for a while and has a large user base. It provides a comprehensive set of UI components and utilities. JSS (JavaScript Style Sheets), on the other hand, is a less known tool for styling in JavaScript. While it has gained some popularity, it is not as widely used as Foundation-Sites.


Foundation-Sites is a complete front-end framework that offers a wide range of pre-built UI components, responsive layout grids, styling options, and JavaScript plugins. It is well-suited for building robust and feature-rich web applications. JSS, on the other hand, is primarily focused on providing a dynamic styling solution for JavaScript applications. It allows you to define styles programmatically using JavaScript objects and provides a CSS-in-JS approach.


Foundation-Sites is designed to be used as a standalone framework, and it may require additional configuration and build setup. It integrates well with other front-end frameworks like React or Angular, but it can also be used with any JavaScript-based project. JSS, on the other hand, is framework-agnostic and can be used with any JavaScript framework or library. It offers seamless integration and can be easily incorporated into existing projects.

Learning Curve

Foundation-Sites is a comprehensive framework with a broad set of features, which may result in a steeper learning curve for beginners. It has a well-documented API and extensive documentation, but mastering all of its capabilities may take some time. JSS, on the other hand, has a simpler and more focused API. It is relatively easy to understand and start using, making it a good choice for developers who prefer a more lightweight and flexible styling solution.

Community and Support

Foundation-Sites has a large and active community of developers. It has been around for a long time, and there are plenty of online resources, tutorials, and community support available. JSS, while not as popular, still has an active community and official documentation, but the resources might be relatively limited compared to a widely adopted framework like Foundation-Sites. However, both packages have GitHub repositories and accept community contributions.

Scalability and Extensibility

Foundation-Sites provides a comprehensive set of features that are tailored for building large-scale applications. It offers customization options and allows you to include or exclude specific components based on project requirements. JSS, on the other hand, provides a flexible and scalable styling approach. It can be easily extended and customized with plugins, and it allows for dynamic and runtime style changes. It is well-suited for both small and large applications.
