Tailwind CSS scroll-smooth Class

The Tailwind CSS scroll-smooth utility applies scroll-behavior: smooth; to an element when added to its class attribute. It enables smooth scrolling animation when scrolling to anchor links or when programmatically scrolling. Creates a polished, animated scroll experience.

This utility is part of Tailwind's Interactivity module, designed for controlling user interaction behaviors such as cursors, text selection, resizing, and scrolling. In Tailwind's utility-first workflow, you add scroll-smooth directly to your HTML elements rather than writing custom CSS. This approach accelerates development and keeps styles co-located with your markup, making it easy to see exactly how each element is styled at a glance.

Common responsive variants include sm:scroll-smooth, md:scroll-smooth, lg:scroll-smooth, and xl:scroll-smooth, allowing different behavior at each breakpoint. State variants like hover:scroll-smooth and focus:scroll-smooth enable interactive styling without any JavaScript. You can also combine multiple variants for fine-grained control over when the utility applies.

This class works well alongside `scroll-auto`, `overflow-auto`, `overflow-y-auto` to build complete, production-ready interfaces. Tailwind's tree-shaking ensures only utilities you actually use appear in your final CSS bundle, keeping file sizes minimal. Browser support for the underlying CSS is excellent across Chrome, Firefox, Safari, and Edge.
