A panel conversation with library and methodology authors and CSS aficionados about recent features added to CSS, developments in how to write more effective, maintainable CSS in small teams and at scale, and what libraries and trends to investigate.

There’s been a lot of exciting work in the CSS color specifications lately, and since the new features are already starting to land in browsers, we’ve been preparing to add support in Sass as well. My proposal for that is published and ready for public feedback!

Cascade layers are an exciting new addition to the CSS specification. A newly released polyfill now provides even greater browser support for the feature.

100% test coverage is a contentious metric! In this piece, Olu explores the impact of pursuing it.

Keeping your project dependencies up to date can become an unwieldy task when Dependabot opens a dozen pull requests every week. We present an alternative approach that uses only one scheduled pull request for all upgrades.

I talk with Claire and Steph about changes to the Container Query syntax, our feelings about web components, named CSS colors, how much we like eating cookies, and other wild tangents.

CSS is evolving rapidly and new features come online all the time. Join Morten & Miriam to talk about what CSS layers and scope are all about and how they will change how we work with and think about the cascade in the future.

TimeDesigner helps school teams rapidly create multiple scheduling scenarios from various perspectives, and plan ahead for future iterations. OddBird helped Tegy plan, design, develop, launch, and maintain their school scheduling web app using CSS Grid and custom property wizardry on the front-end, and well-tested Django/Python on the back-end. Currently, the…
