Open Source Tools

We build tools that millions of developers rely on

We contribute to open tools & standards when we can, giving back to the open web. Lately we’ve had a focus on CSS and related platform features, with Miriam joining the W3C as an Invited Expert. But that work takes resources, making it hard for independent contributors like us to stay involved. If you appreciate what we’re doing, you (or your company) can sponsor our work directly.

Automated style guides

OddBird (creators) since

Design systems streamline development, communication, and consistency – but often rely on dedicated teams and extended budgets.

Herman helps you keep your development process simple – and your UX consistent – as you scale over time.

True

Unit-testing for Sass developers

Miriam, Jonny, Carl, David G, & Kit (creators) since

True is the only full-featured unit-testing framework designed specifically for the Sass language. Write your tests in Sass, compile them with Sass, and then (optionally) pass the results to a Javascript test-runner for command-line control and reporting.

    Practical media helpers for Susy3

    by Miriam Suzanne on

    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…

    Make grid systems your fallback plan

    by Miriam Suzanne on

    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.

    Understanding ‘Spread’ in Susy3

    by Miriam Suzanne on

    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.

    Code Patterns & Style Guides

    by Miriam Suzanne on

    Living Style Guide documentation on the web is a difficult problem, gaining a lot of attention in the last few years. Let’s take an in-depth look at one way to store patterns directly in Sass, and generate documentation automatically.

    Generating Code Documentation for Polyglot Projects

    by David Glick on

    Code documentation is ideally written as close to the actual code as possible, but compiled into a comprehensive set of documentation that includes code from all languages in use. Here’s how we intend to do that.

    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.

    Isolation and Bleed in Susy

    by Miriam Suzanne on

    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.

    Susy Next, The First Alpha

    by Miriam Suzanne on

    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.

    Sass Layout in 2013 and the Future of Susy

    by Miriam Suzanne on

    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?
