17 CSS Flowcharts

This collection demonstrates methods for creating responsive flowcharts and organizational diagrams using only HTML and CSS. The primary technique relies on Flexbox and nested lists to build hierarchies, where connecting lines are drawn via ::before and ::after pseudo-elements. For more complex 2D structures, CSS Grid is applied to ensure precise node positioning. Interactivity is added using modern selectors (like :has()) and transitions, allowing entire data branches to be highlighted on hover for better readability.
