border-color property allows you to set the border color of a box.
border-color property is a shorthand property for
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.
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
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.
