ADVANCED SASS AND LESS USAGE IN DYNAMIC UI FRAMEWORKS

Abstract

In the dynamic and fast-paced realm of front-end web development, the need for scalable, maintainable, and responsive user interface (UI) solutions is increasingly critical. CSS preprocessors like SASS (Syntactically Awesome Stylesheets) and LESS (Leaner Style Sheets) have become instrumental in addressing these needs by introducing variables, functions, mixins, nesting, and modular architecture into traditional CSS workflows. This paper explores the advanced usage of SASS and LESS in conjunction with dynamic UI frameworks such as React, Angular, and Vue. It delves into their role in creating component-based design systems, efficient theming structures, and modularized stylesheet architectures. Special focus is given to features like control structures, reusable style patterns, and performance enhancements via preprocessor-based optimizations. Moreover, the study evaluates real-world implementation patterns, best practices, and pitfalls to avoid, backed by insights from blog articles, documentation, and industry case studies. The integration of SASS and LESS into modern frontend workflows not only simplifies code complexity but also enhances maintainability, responsiveness, and developer productivity. By highlighting the synergy between preprocessors and modern UI frameworks, this research underlines their indispensable value in professional web development environments.
