CSS's competing goals and cascade origins

Miriam Suzanne joins the podcast to unpack the surprisingly deep world of CSS value resolution, the browser program running beneath every website. She explains how cascade and inheritance work together, why CSS custom properties introduce invalid at computed value time errors, and how CSS functions and mixins change the game. Plus: is Sass actually dead, or does it still solve real problems that the browser can't touch?
