Tailwind CSS sticky Class

The Tailwind CSS sticky utility applies position: sticky; to an element when added to its class attribute. It positions the element as relative until it reaches a specified scroll threshold, then it becomes fixed. Perfect for headers that stick when scrolled past and sidebar navigation.

This utility is part of Tailwind's Layout module, designed for controlling element display types, positioning methods, and document flow behavior. In Tailwind's utility-first workflow, you add sticky 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:sticky, md:sticky, lg:sticky, and xl:sticky, allowing different behavior at each breakpoint. State variants like hover:sticky and focus:sticky 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 `fixed`, `relative`, `absolute`, `static` 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.
