This template uses the same CSS property as {{clear}}, but has additional float property to place on the left or right side of the page. This can insert an invisible breakpoint to indicate that a floating element should be placed at its position. So this template makes element placed under the upper element to make existing content is completed in the maximum width of columns, and make it possible to stop element from flowing next to upper element to produce an useless blank between the element and the side of page.
