Wirefy is a responsive browser-based framework designed to create functional wireframes using standard elements. It is a collection of CSS and JS files that allows you to experiment with responsive wireframes quickly.
Designed and created by Chris Da Sie, Wirefy follows the philosophy of mobile first, which makes it respond to the proper viewport. It is style agnostic, meaning that clients won’t have to get hung up on the design elements like colors and fonts.
Aside from the CSS and JS, it is also a collection of functional responsive HTML snippets, which means that it can be very beneficial to those who build HTML prototypes.
This framework includes styles for all major web design elements such as images, typography, grid, forms, buttons, pagination and a whole lot more. It builds on tools including the Frameless grid system and Botstrap, and has CSS media queries for adapting different device resolutions
