CSS border-color Property
The CSS border-color property is a shorthand for setting the color of the four sides of an element’s border. It is shorthand for the following properties:
border-top-color
border-right-color
border-bottom-color
border-left-color
Each side can have its own value. The border-color property is used with the border-style property. If the value is 0, the border-color property has no effect.
This property takes any CSS colors value. Default color is the current color of the element.
The border-color property can have 4 values. If it has one value, the color is applied to all four borders. If it has two values, the first value is set to the top and bottom borders, the second value is set to the right and left. If it has three values, the first one is applied to the top border, the second one to the right and left, and the third one to the bottom. If it has four values the first is set to the top, the second to the right, the third to the bottom and the fourth to the left.
