After years of developer frustration and questions on online forums, it’s finally happening: CSS is getting an if() function to apply styling when a condition is met. For the first time, developers can make logical decisions directly in stylesheets, without separate code blocks. This opens up whole new possibilities for web designers.
This breaks with the foundations of CSS. You already can build if-like statements especially since the implementation of custom properties. It doesn’t have to be that explicit — quite the contrary: putting if() into every property will make them bloated and harder to understand.
