Why is it a good practice to avoid using IDs for styling?
Article Introduction：There are three major problems with using ID for style design: first, the ID selector is too specific and makes it difficult to overwrite; second, the ID cannot be reused to force code duplication or structural compromise; finally, modern development has better alternatives. The high specificity of ID makes style modification difficult, easily causing redundant code and!important abuse; the limitation of ID uniqueness in HTML hinders style reuse, while class selectors naturally support multi-element reuse; currently available tools such as BEM, CSS-in-JS and Tailwind provide greater flexibility and maintainability. Although IDs are useful in anchor linking or JavaScript positioning, they should be avoided for style design to ensure scalability and consistency of CSS.

Nested use is not supported: has(:has(...)); 3. The selector should be kept concise to avoid performance problems. Alternatives include adding class manually
