The outline is a line drawn around the element, located outside the edge of the border. The outline-color attribute is used to set the color of the visible part of the entire outline of an element. The outline-style attribute must always be declared before the outline-color attribute; an element cannot change its color until it has an outline.

Note:

Always declare the outline-style attribute before the outline-color attribute. The color of an element's outline can only be changed after it has obtained its outline.
