Frag is a fluid, responsive, simple grid system for CSS. Frag is easy to use and highly configurable, you can use it with either plain CSS or Sass.

To get started with Frag, read the documentation:

Why Frag?

Frag aims to provide you with a simple grid system, nothing more. I built frag originally because there were not many responsive frameworks out there which did exactly as I wanted them to – old IE support and no extra cruft. I talk a little more about Frag in this post.


Frag 1.0 supported LESS as well as Sass, and handled things a little differently. The Frag 1.0 site is still available here.
