CSS Walker Physics Demo

This interactive demo features animated walkers that users control through drag and flick interactions. Walkers can be added via button or code, then manipulated by dragging or flicking them across the page. When the window is resized, walkers respond dynamically by riding on surfaces and launching airborne during fast resizing. The demo showcases various CSS elements with different physical behaviors: stairs, floating platforms, walls, and cards that reflow when the window narrows. Borders, buttons, and form fields form solid barriers capable of trapping walkers, while text serves as a landable floor that doesn’t obstruct passage. Lines of text are spaced closely enough that they never block walkers from dropping between them. A long floor at the bottom catches any walkers falling through the entire demo.
