This is a floated paragraph with some styles applied in order to show its extent.

This is a normal-flow paragraph of text with a border. It is followed by a div that’s been made into a grid.

This is a paragraph that comes after the grid in the normal flow. Notice how the grid does not “slide under” the float, as normal-flow elements do. In this sense, the grid acts sort of like a float, although it is still a block box in the normal flow.
