The border-color attribute is a shorthand attribute that can be used to set the color of all four borders of an element, or to set different colors for the four sides.
CSS border-color property
Function: border-color property Used to set the border color of an element. You can set 1 to 4 values:
border-color:red green blue pink;
● The upper border is red
●The right border is green
●The lower border is blue Color
●The left border is pink
border-color:red green blue ;
●The top border is red
●The left and right borders are green
●The bottom border is blue
border-color:red green;
● The top and bottom borders are red
● The left and right borders are green
border-color:red;
● All four borders are red
Note: The border-style attribute needs to be declared before the border-color attribute, because the element must obtain a border before changing its color. And the value of the border-style attribute cannot be none or hidden, otherwise the border will not appear and the border-color attribute will not take effect.
