To refactor CSS files to MDN best practices, you provide the file path to a modernization process that replaces deprecated properties, consolidates repetitive rules, and introduces variables and semantic selectors. A timestamped backup and a refactoring report are generated.

Modernizing legacy CSS across large style sheets involves consolidating repetitive rules, replacing deprecated properties, and applying MDN-recommended layout techniques, variables, and cleaner selectors to improve readability and reduce duplication.

CSS refactoring handles deprecated properties and repetitive rules by automatically replacing outdated syntax with modern alternatives and consolidating duplicated declarations, ensuring the final style sheet remains maintainable and aligned with MDN guidance.

Yes, you can refactor CSS for web projects with multiple components and themes. The process applies modern layout techniques, semantic selectors, and variables across your style sheets to ensure maintainability and consistency throughout the project.

Refactoring CSS does not modify your original files without backups. The process automatically creates timestamped backups before applying any changes, ensuring safety and traceability while logging the rationale for each modification.

You need to use CSS variables and semantic selectors during refactoring when you want to reduce duplication, improve readability, and modernize syntax across large style sheets, replacing repetitive rules with maintainable, MDN-guided patterns.
