CSS Working Group

CSS is the design language of the web, with a focus on total surfer control and customization. From your browser preferences, you can re-design any website!

I’m an editor on several CSS specifications:

Cascading & Inheritance, levels 5+
Conditional Rules, level 5
Values & Units, level 5
Functions & Mixins, level 1 (Editor’s Draft)

I’ve had a lead role in defining popular features like cascade layers, container queries, scope, mixins, functions, and (recently) value-mixing.

You can follow along, or even help out by sponsoring my work on features that matter to you.
