The Declarative Power of CSS Selectors
summary
Digs into concrete selector tricks: use attribute selector matching .pdf to add icons from hrefs, substring operators to target file extensions, and :not(...) to flag missing alt or table summary for accessibility by outlining those elements. Shows a JS-free accordion via :target using max-height animation (works but requires a guessed max value), and recommends querySelector/querySelectorAll for DOM selection. Notes CSS4 ideas like a parent selector and :matches(), and current browser support limits.
