The border-color, border-radius, border-style, and border-width CSS properties are used to control the appearance of an element's border.


border-color: specifies the color of the element's border.

border-radius: specifies the roundedness of the element's corners.

border-style: specifies the style of the element's border.

border-width: specifies the thickness of the element's border.


The padding-bottom, padding-left, padding-right, and padding-top CSS properties are used to control the amount of space between an element's content and its border. These properties can be used to add padding to the top, bottom, left, and right sides of the element, respectively.
