CSS border-color

The CSS border-color property allows you to set the border color of a box.

The border-color property is a shorthand property for border-top-color, border-right-color, border-bottom-color, and border-left-color. If you only want to specify a border color for some sides (but not all sides), you can use one or more of those properties instead.

Note that you will also need to ensure that border-width is not 0 and that border-style is not set to none or hidden before the border is displayed.


Possible Values

Specifies the color of the border. It must be a valid color.

You can provide between one and four color values. If you provide all four values, these set the top, right, bottom and left border, respectively.

The following examples demonstrate how the number of values affects the outcome.

One Color Specified

Two Colors Specified

Three Colors Specified

Four Colors Specified

In addition, all CSS properties also accept the following CSS-wide keyword values as the sole component of their property value:

Represents the value specified as the property's initial value.
Represents the computed value of the property on the element's parent.
This value acts as either inherit or initial, depending on whether the property is inherited or not. In other words, it sets all properties to their parent value if they are inheritable or to their initial value if not inheritable.
