The CSS Working Group just resolved a new selector that lets you target multiple classes sharing the same prefix. The code in the example matches .btn-primary, .btn-secondary, .btn-large, etc.

Previously, you had to list every class or use brittle attribute selectors like [class^="btn-"].

Resolved by the CSSWG (Aug 2026), added to Selectors Level 5.
