The border-top property
The border-top property specifies a color,
type, and width for a top border. It is a shorthand
property for
border-top-width,
border-top-style
and border-top-color.
Syntax

border-top: width type color;
}
The order of the properties does not matter.
Example
Let's give the element a black top border
with 2px width:
<div id="elem"></div>
#elem {
border-top: 2px solid black;
background: #f9f9f9;
width: 300px;
height: 100px;
}
