The term "rounded corners" refers to a design feature in which the edges or borders of an object are curved, rather than being sharply angled. This can create a softer and more visually appealing appearance, as well as reducing any potential for injury caused by sharp angles. The phrase is often used in reference to graphic design elements such as icons, logos, and website layouts, where rounded corners on buttons or other visual elements can help to create a cohesive look and feel across the entire interface.
