Responsive A super lightweight HTML, CSS, and JavaScript framework for building responsive websites

Bootstrap and Foundation are too heavy.

They're great for prototyping but every time you start a real, front-facing, project with them you have to overwrite lots of designer styles that do nothing to add to the functionality of the website. That's annoying!

Responsive has been built with that in mind. It has been specifically designed and coded to be as lightweight as possible to prevent the need to undo styles set by the framework itself and allow developers to write efficient code and speed up development time.

Responsive is tiny. The combined CSS and JavaScript is only 24.8kb minified and gzipped but there is a lot of functionality built into the framework. It's designed to be dropped-in, as-is to your website such as you would with Normalize.css.
