Tailwind CSS duration-100 Class

The Tailwind CSS duration-100 utility applies transition-duration: 100ms; to an element when added to its class attribute. It sets the transition duration to 100ms. A quick transition for snappy interactions like hover effects and small UI state changes.

This utility is part of Tailwind's Transitions module, designed for adding smooth CSS transitions with configurable duration, timing, and property targeting. In Tailwind's utility-first workflow, you add duration-100 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:duration-100, md:duration-100, lg:duration-100, and xl:duration-100, allowing different behavior at each breakpoint. State variants like hover:duration-100 and focus:duration-100 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 `duration-75`, `duration-150`, `duration-200`, `transition` 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.
