![Modernizing the Pinterest carousel: 90% less code with native CSS
How do you build a web that inspires 600 million users? At Pinterest, the Close Up experience is core to how users discover ideas. But over time, the JavaScript powering carousel experience became a patchwork of 2,000 lines of code—resulting in noticeable lag and jank for users.
In this video, Pinterest engineers Calvin and Anuja walk through how they swapped legacy JavaScript for modern CSS carousels and View Transitions. The results? A 90% reduction in code, a 15% improvement in page load time, and a smoother, native-feeling UI.
