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.

Cascading Style Systems

A workshop on resilient & maintainable CSS

New CSS features are shipping at an unprecedented rate – cascade layers, container queries, the :has() selector, subgrid, nesting, and so much more. It’s a good time to step back and understand how these tools fit together in a declarative system – a resilient cascade of styles.
