- 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.

- CSS container queries explained
- Container query solves the context dependency problem of traditional media queries by letting components respond according to the parent container size rather than the viewport size. 1. First, use container-type or container-name to define the query container, 2. Then use @container to write conditional styles instead of @media, so that components are adaptable in different layouts, supporting nested, multi-condition and named containers, suitable for grid, CMS and design systems. Modern browsers have good support, truly realizing component-level responsive design.

- How to use CSS columns property?

Use column-span:all to make specific content such as titles span all columns; 4. Pay attention to compatibility issues. Some old browsers have poor support, and some HTML elements may perform abnormally in multiple columns.
