"I'll admit, when container queries first shipped back in 2022, I didn't really pay attention. I mean, why container size queries when we already have media queries? Why container style queries when custom properties inherit anyway (they don't work with standard properties... yet)? Their use cases seemed like edge cases to me, enabling us to do things that we could already do but in a different way."
"The latest container query feature is anchored container queries, which enable us to query fallback positions. Imagine that you anchor-position a tooltip caret to the left side of a tooltip, but then there's no room to display the tooltip, so you flip it to the opposite side of whatever triggers it using position-try-fallbacks: flip-inline. Well, an anchored container query can detect when the tooltip position is flipped so that we can also flip the tooltip caret to the opposite side of the tooltip."
Container queries expanded responsive CSS by allowing components to adapt based on container properties rather than viewport size. Size queries enable component-level layout changes. Style queries (including the new range syntax) permit style adjustments scoped to containers, addressing limitations of property inheritance. Scroll-state queries reveal whether a container is scrollable, scroll-snapped, or has sticky elements in a stuck state, with evolving distinctions like scrolled support. Anchored container queries detect fallback or flipped positions, enabling UI elements such as tooltip carets to mirror flipped placements. The possibilities suggest many more targeted container queries could emerge to capture computed values and localized state.
