#if

The CSS if() function introduces real conditional logic to CSS. It allows you to write conditions inline instead of relying on media queries or workarounds : Works with style() , media() , and supports() queries for theming, responsive tweaks, and state-based styling Fits property-level decisions, while media and container queries still handle broader layout changes Supports nested logic and pairs well with calc() for advanced patterns Currently supported only in Chromium browsers, so use progressive enhancement and @supports checks
