The Future of CSS: Target Multiple Classes with the Class Prefix Selector

CSS is introducing a new Class Prefix Selector (.prefix-*) that allows developers to target multiple classes sharing the same prefix with a single rule, eliminating the need for repetitive selectors or brittle attribute selectors. Resolved just two weeks ago by the CSS Working Group, this feature will simplify styling of grouped elements in utility classes and design systems, though it remains in specification phase and not yet available in browsers.
