A Handy Use For Cascade Layers

The article explains how CSS Cascade Layers can solve a specificity problem in a live coding demo. The author wanted default styles at the bottom of a stylesheet but needed to write demo-specific layout code at the top. Cascade Layers allow defining the layer order, ensuring styles in lower-priority layers (like resets) apply first, even if written later in the file. It covers browser support, a PostCSS polyfill, and a caveat with a container queries polyfill.
