css outline-offset property syntax


How to use the outline-offset attribute?

Theoutline-offset property sets the distance between the outline and the edge of the border. Basic syntax: outline-offset:length; indicates that the distance between the outline and the border is length. The unit of length can be an absolute unit (such as px) or a relative unit (such as %).

Function: The outline-offset property offsets the outline and draws it on the edge of the border. Outlines differ from borders in two ways: outlines take up no space, and outlines may be non-rectangular.

Syntax: outline-offset: length|inherit;

Description: length Outline and border edge distance. Inherit specifies that the value of the outline-offset attribute should be inherited from the parent element.

Note: All major browsers support the outline-offset attribute, except Internet Explorer.
