Style outlineWidth attribute

Definition and usage

outlineWidth Sets or returns the width of the outline around the element.

The outline is a line around the element. It is displayed around the element's margin. However, it is different from the border property.

The outline is not part of the element's size, so the width and height attributes do not include the outline width.
