Foundation is a family of responsive front-end frameworks that make it easy to design beautiful responsive websites, apps and e-mails that look amazing on any device.

Foundation frameworks are easy to use, powerful, and flexible framework for building prototypes and production code on any kind of device.

Foundation for Sites was our first framework. It provides the tools and resources like a simple yet flexible layout grid, modal boxes, typography, navigation components, and form elements that designers can quickly plug into their products.

Based on Sass, the CSS preprocessor, designers can pick and choose which components they want, write HTML semantically, and control almost every aspect of the framework with a series of built-in variables.

Foundation's is written with the most popular browsers in mind — specifically, mobile devices like smartphones. To that end its grid takes a mobile-first approach. Designers give each layout block a series of instructions depending on screen size. Mobile-first means Foundation's grid assumes the smallest configuration until told otherwise. For example, instructions for medium screens, like tablets, override instructions for smartphones. Likewise, large instructions override medium.

Foundation for Sites is written with humans in mind two ways. First, its components and grid use people-friendly names and instructions. Second, Foundation for Sites includes accessibility options for screen readers. The end result is a framework that helps both designers and end users get up and running quickly because we don't want to waste time reinventing the grid.
