outline-offset

The outline-offset CSS property sets the amount of space between an outline and the edge or border of an element. An outline is a line that is drawn around an element, outside the border edge. The space between an element and its outline is transparent; in other words, it is the same as the parent element's background.

/* <length> values */
outline-offset: 3px;
outline-offset: 0.2em;

/* Global values */
outline-offset: inherit;
outline-offset: initial;
outline-offset: unset;
