CSS Working Group has approved the if() function, bringing true conditional logic to stylesheets. This new function allows inline conditional styling using syntax like `property: if(condition: value; else: fallback)` with support for style(), media(), and supports() queries. Unlike traditional approaches requiring separate media query blocks or complex custom property toggles, if() keeps conditional logic centralized within property declarations. The function enables advanced patterns like nested conditions, integration with calc(), and conditional shorthand modifications, making components more adaptive and self-contained while reducing code fragmentation.
