The Web Development Podcast with Fexingo: Frontend, Backend, and Modern Web Stack

Why Your CSS Framework Is Making Your Site 800KB Heavier


Listen Later

Episode 3 of The Web Development Podcast dives into the hidden bloat of CSS frameworks. Lucas and Luna break down why a typical Bootstrap 5 setup delivers over 800KB of unused CSS — and how modern alternatives like utility-first Tailwind CSS or CSS Container Queries can slash that to under 10KB. They walk through real-world numbers from a 2025 e-commerce site rebuild, compare the bundle-size impact of popular frameworks, and explain why the web's median page weight has crept past 2.5MB. If you've ever wondered whether your CSS framework is slowing down your users, this episode gives you the data to decide — plus practical tips for auditing your own stylesheet with tools like PurgeCSS and Chrome DevTools coverage reports.
