CSS outline-color Property

The outline-color property defines the color of an outline.

An outline is a line that is drawn around an element. But it is different from the border property. The width and height properties of an element do not include the outline width because the outline is not considered a part of the element’s dimensions.

The outline-color property does not work if you use it alone. It must be used with the outline or outline-style properties.

Hexadecimal, RGB, RGBA, HSL, HSLA or color names can be set as a value for the outline-color property. See the color values in the HTML colors section.
