The web is a responsive place, from your lithe & lively development process to your end-user's super-tablet-multi-magic-lap-phone. You need grids that are powerful yet custom, reliable yet responsive.

Susy grids are fluid on the inside, ready to respond at any moment, but contained in the candy shell of your choice, so they respond how and when and where you want them to.

We don't design your site or dictate your markup, we just do the math and get out of your way.

Version 1.0.rc.0

gem install susy --pre

Version 0.9 (deprecated)

gem install compass-susy-plugin

Why is 1.0 a release candidate?

Susy 1.0 is stable, tested, & feature complete; but our launch depends on unreleased Compass and Sass features. We think those features are stable as well, and you should get started with Susy 1.0 RC right now. We'll make sure the final upgrade is as painless as possible.
