This example demonstrates how CSS floats affect the layout of text and block elements within an HTML document. It uses standard HTML elements and the CSS properties `float`, `margin`, and `display: flow-root` to create left- and right-floating black squares that wrap surrounding paragraph text. The page pulls the Roboto font from Google Fonts via `@import` and applies it to the body, while the `section` element showcases `flow-root` to contain nested floats. No JavaScript or external visualization libraries are used; the effect relies entirely on core CSS.
