Abstract

nMany modern websites suffer from bloated and ineffective stylesheets, despite the fact that CSS is crucial for user experience and web performance. The effects of CSS optimization strategies, including minification, modularization, critical CSS extraction, lazy loading, and unused rule elimination, are simulated and assessed in this study on four representative web platform types: news portals, e-learning platforms, e-commerce sites, and SaaS dashboards. Using a controlled experimental environment and common auditing tools (Chrome DevTools and Google Lighthouse), key performance indicators such as Time to Interactive (TTI), CSS file size, First Contentful Paint (FCP), and Largest Contentful Paint (LCP) were measured both before and after optimization. According to the simulated results, CSS payload sizes can be decreased by more than 95% and load times can be improved by up to 60%. Furthermore, after optimization, significant gains were shown in proxy behavioral indicators like bounce rate and conversion rate. These results show both technical and behavioral impact, which supports the wider applicability of CSS optimization techniques. The study adds a reproducible methodology and empirical-style data to the field of frontend performance engineering.nn
