The outline-width property sets the physical width of the outline. This property is not inherited.

An outline is a line drawn around an element with the purpose of making that element stand out (i.e., become more noticeable on a page). You can set the color, style, and width of the line. The outline is drawn outside of the border edge of the element. Therefore, an element can have both a border and an outline. Unlike a border, an outline does not have to have a rectangular shape.
