- How to clear floats in CSS?
- There are four common ways to clear floats: 1. Use clear: both to match empty elements, and implement them by adding extra HTML elements. The advantage is that they are simple and compatibility, but the disadvantage is that they are not semantic enough; 2. Use pseudo-element::after to clear floats, and implement them by adding clearfix class to the parent container, which is recommended for modern projects; 3. Use overflow attributes, the code is concise but may hide overflow content; 4. Use Flexbox or Grid layout, as a modern alternative, there is no need to clear floats, and the layout is more flexible but incompatible with old browsers. Compatibility, structure and maintenance costs must be considered comprehensively when selecting a method.
