Foundation is the most advanced responsive front-end framework in the world. Quickly go from prototype to production, building sites or apps that work on any kind of device with Foundation. Includes a fully customizable, responsive grid, a large library of Sass mixins, commonly used JavaScript plugins, and full accessibility support.
A Utility-First CSS Framework for Rapid UI Development. Tailwind is different from frameworks like Bootstrap, Foundation, or Bulma in that it's not a UI kit. It doesn't have a default theme, and there are no built-in UI components. On the flip side, it also has no opinion about how your site should look and doesn't impose design decisions that you have to fight to undo. If you're looking for a framework that comes with a menu of predesigned widgets to build your site with, Tailwind might not be the right framework for you. But if you want a huge head start implementing a custom design with its own identity, Tailwind might be just what you're looking for.
