Article Introduction：The float attribute of CSS was originally designed to achieve the layout effect of text surrounding images, but was later widely used in page layout. float will cause elements to be separated from the document stream and arranged to the left or right, while other content surrounds it; multiple floating elements will be arranged horizontally as space allows, otherwise they will "drop" below. However, floating causes the parent container to collapse highly, which in turn causes release issues, so floating needs to be cleared. Common ways to clear floats include: 1. Add empty elements with clear:both after the floating element; 2. Use clearfix pseudo-element techniques; 3. Use modern layout methods such as Flexbox or Grid to replace float. Which method to choose depends on the project structure and browser
