Detect fallback positions with anchored container queries from Chrome 143

Read Original

This article explains the new anchored container queries feature in Chrome 143, part of the CSS Anchor Position Level 2 spec. It solves the problem where CSS could reposition an anchored element (like a tooltip) using fallbacks but couldn't apply different styles based on the chosen fallback. The post details how to use `container-type: anchored` and `@container anchored(fallback: ...)` queries to style elements contextually, such as changing a tooltip's arrow direction when it flips positions.
