Getting Started with Anchor Positioning

This article introduces the Anchor Positioning API, a new browser feature that simplifies attaching floating elements like tooltips and dropdown menus to their triggers without JavaScript. It explains the core concepts of anchor and target elements, demonstrates a basic 'Hello world' example with CSS code, and focuses on the most useful 20% of the API to solve 80% of real-world UI positioning problems. The tutorial covers how to use anchor-name, position-anchor, and position-area properties to prevent overflow and handle edge cases.
