Foundation was designed for and tested on numerous browsers and devices. It is a mobile-first responsive framework built with Sass/SCSS giving designers best practices for rapid development. The framework includes the most common patterns needed to rapidly prototype a responsive site. Through the use of Sass mixins, Foundation components are easily styled and simple to extend.
In addition to the regular HTML elements, Foundation contains other commonly used interface elements. These include buttons with advanced features (for example, a grouping of buttons or buttons with the drop-down option, make and navigation lists, horizontal and vertical tabs, navigation, breadcrumb navigation, pagination, etc.), labels, advanced typographic capabilities, and formatting for messages such as warnings.
