Michael Hladky joins the pod to explain how CSS performance improvements like content-visibility, CSS containment, contain layout, and contain paint can dramatically outperform JavaScript virtual scrolling. The conversation explores virtual scrolling, large DOM performance, and how layout and paint work inside the browser rendering pipeline, including recalculate styles and their impact on INP Interaction to Next Paint. Michael shares real-world examples of frontend performance optimization, discusses cross-browser CSS support including Safari content-visibility, and explains why web performance issues tied to rendering are often misunderstood and overlooked. --- Links LinkedIn: https://www.linkedin.com/in/michael-hladky-519340148/ GitHub: https://github.com/BioPhoton X: https://x.com/Michael_Hladky --- Resources Conference link: https://push-based.io/event/perfnow-2025-michael-hladky-zero-js-virtual-scrolling-css Conference resource: https://github.com/push-based/css-contain-and-content-visibility-research --- Fill out our feedback form to help us improve PodRocket! https://forms.gle/xHm5PdAasfYqXYzT7 --- Chapters --- 🎙 Listen to PodRocket 🎧 Spotify: https://open.spotify.com/show/6oFuKu8... 🎧 Apple Podcasts: https://podcasts.apple.com/us/podcast... 📺 Subscribe on YouTube: @LogRocket Follow on Socials ➡️ Noel Minchow, Host ➡️ Michael Hladky, Guest ➡️ Elizabeth Becz, Producer ➡️ LogRocket, PodRocketPod --- What does LogRocket do?
