Lightweight & Flexible

Copy permalink to “Lightweight & Flexible”

Not everyone can play with the latest specs, and there will always be edge-cases that require manual grid-math. Susy3 is trimmed down to the most basic features: a lightweight library of functions that can be used along with float, or flexbox or any other CSS – anywhere, any time.

Susy is also available in the CodeKit editor, with 10% of your purchase going to Black Girls Code when you follow the link from our site. You can also still access Susy2 documentation if necessary.

A few of the sites (mobile & desktop) that were built with Susy

I like the idea of grids-on-demand, rather than a strict framework.

—Chris Coyier, Founder at CSS-Tricks

My experiments have left me impressed. The current state of CSS layout means that unless you like to spend a lot of time doing calculations something like Susy is really useful. The output CSS is pretty much what I’d come up with myself, which to me is the acid test for tool use.

—Rachel Andrew, Invited Expert at W3C CSSWG

If you’re interested in reading Sass poetry, be sure to look at Susy’s source code!

Susy & Zendesk have been getting along magically. It’s precisely what you need, and nothing more.

Several people have asked recently why container queries aren’t being used more broadly in production. But I think we underestimate the level of legacy browser support that most companies require to re-write a code-base.

Most grids change with the viewport – and Susy needs new settings at each breakpoint. Susy3 is designed without mixins for complete flexibility from project to project, but it can be useful to build additional tools and shortcuts as you go. Here are some snippets to help you get started…

We’re excited to introduce Susy 3.0, a major update to our popular grid-math calculator – now more focused and flexible than ever. Susy was designed to make layout math easy, without forcing you into generic patterns and ugly markup. But grid systems are on the way out, replaced by real CSS layout specs that live in the browser. With Susy3, we want to help make that a smooth transition.

Susy 3.0 will be released in the next week, if all goes well, and there’s a lot to write about it. I wanted to start with a detailed overview of one core concept: spread.

Susy Next alpha 5 is out, and loaded with changes. We now require Sass 3.3, we no longer require Compass, and there have been major syntax improvements. We’re getting real close to launch, and we’d love to know what you think. Play around, and let us know!

We haven’t written full docs yet, and this blog post will be vastly incomplete, but I’ll give you a quick rundown of where we’re going. This is all open to change, of course. There’s a reason we’re still in alpha.

A few new features have landed in Susy 1.0.7, even as we work on more integrated syntaxes for 2.0. The isolate() and isolate-grid() mixins help you manage the worst effects of sub-pixel rounding, while bleed() helps you break items out of the box.

Last night we released the very first alpha build of Susy Next. This release is extremely sparse. What we have built is a background ‘engine’ for calculating grid math. There are some rough first steps towards api and syntax, but they are more “proof of concept” experimentation than usable interface.

The web is littered with grid systems and ‘frameworks’ that force your code & design into narrowly defined patterns. Even the most semantic of us have had to push specialized techniques in order to create a usable syntax.

But Sass has come a long way, and I’m convinced that it’s time for something new.

What if you had a layout system that bends completely to the needs of your site? What if you could use one unified syntax for handling responsive layouts of any kind? What if you had a modular system that let you mix-and-match to customize for every site, and change your output with simple extensions?

The off-canvas layout pattern for responsive web design has been getting all the attention lately, and I’ve had several people ask how Susy One might play along. I’ll show you how easy it is, and how much flexibility Susy can add along the way.
