Foundation is the first and most advanced responsive front-end framework in the
world. It lets you quickly prototype and create sites and apps that work on any device (smartphones up through
desktops and TV displays) with a library of tested components.
Foundation doesn’t require any particular back end. In fact, Foundation has been
used with dozens of back-end and CMS technologies, and Foundation is used by hundreds of thousands of sites
every day to deliver rock-solid responsive sites.
What are Front-end Frameworks?
Just like there are frameworks for building native app interfaces (like Xcode for
iOS), Foundation is a framework to build the front-end, or client-facing part, of a website or web application.
Foundation runs entirely in the browser, so it’s easy for a Design or UX specialist to get into and work
on locally without involving IT.
Foundation is Mobile First
Mobile First is two parts technology and two parts philosophy. Foundation is built
in such a way that it encourages a mobile-first approach, designing your site or app for the small device
first, then expanding that to include larger displays and more full-featured devices. While it’s not required,
building this way in Foundation is relatively simple and introduces really useful constraints in product
design. We’ve found it to be a big win in designing effective, ubiquitously available products.
