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.
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.
A huge thank you to the individuals and organizations sponsoring OddBird’s open source work!
We love contributing back to the languages & tools that developers rely on, from CSS & Sass to browser polyfills and Python. Help us keep that work sustainable and focused on developer needs!
