CSS border-top-right-radius Property
Description
The border-top-right-radius CSS property is used to define the curvature or roundedness of the top-right corner of an element, typically a box or a container, in a web page layout. It allows web developers to create visually appealing designs by specifying a radius value, which determines the size of the quarter-circle that defines the corner's curve. This property is part of the broader border-radius property and can be used in combination with other corner radius properties to control the roundness of specific corners, giving web designers fine-grained control over the element's appearance.
