Remarks
The border-top property is a shorthand property that sets the width, color, and style values for the top border of an object.
All individual border properties not set by the shorthand border-top property are set to their initial values. For example, the initial value for width is "medium".
If a color is not specified, the text color is used.
For more information about supported colors, see the Color Table.
Examples

div {
border: 2px solid black;
height: 50px;
width: 50px;
}
.top {
border-top: 2px dashed #00BFFF;
}
