Flow Charts with CSS Anchor Positioning

The introduction of the CSS Anchor Positioning API in Chrome 125 simplifies complex positioning tasks like creating popovers and tooltips by allowing elements to be positioned relative to others. This technique can also be applied to create basic flow charts using just CSS. The post explains how to define unique anchor names and positions, demonstrates anchoring elements to multiple other elements, and explores creating flow chart nodes and lines with CSS pseudo-elements. Advanced techniques for creating multiple node flow charts and draggable flow charts using a bit of JavaScript are also covered.
