Last Updated :
17 Sep, 2024
The CSS border-color property allows developers to define the color of an element's border, enhancing the visual design of a webpage. It works in conjunction with the border property to provide control over the appearance of borders using various color values like-named colors, hex codes, or RGB values.
By combining border color with border-style and border width, you can create custom borders. For example, using border-color: red green blue yellow; apply different colors to each side of the border, adding a creative touch to your design
Syntax
border-color: color-value;
Multiple Sides Syntax
border-color: top-color right-color bottom-color left-color;
Default Value: The current color of the element
