Not because it was buggy — because it didn’t need to exist anymore. A resize observer that toggled a class based on container width, a form validation script that just added an “invalid” class to a parent div, a PostCSS plugin that faked layer-like ordering — all three jobs are now native CSS. This post is a walkthrough of the three features that made that possible: container queries, :has(), and cascade layers, plus native nesting and scroll-driven animations along the way, with real code for each.
