The Tailwind CSS rounded utility applies border-radius: 0.25rem; /* 4px */ to an element when added to its class attribute. It applies a 4px border radius to all corners. The standard subtle rounding for buttons, inputs, cards, and most UI elements.
This utility is part of Tailwind's Borders module, designed for adding border widths, styles, radii, and dividers to visually define element boundaries. In Tailwind's utility-first workflow, you add rounded 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:rounded, md:rounded, lg:rounded, and xl:rounded, allowing different behavior at each breakpoint. State variants like hover:rounded and focus:rounded 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 `rounded-none`, `rounded-sm`, `rounded-md`, `rounded-lg` 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.
