The 'outline-color' property specifies a color for the outline for
The outline properties create a uniform line around an object in order
to draw visual attention. An outline is slightly different than a border
in several ways: An outline is drawn starting "just outside the border
edge" and is allowed to be non-rectangular. Outlines are always rendered
on TOP of an element's rendering box and do not influence the
box's position or size calculation; the document does not need to be
re-flowed when a border is rendered or hidden, but the outline may
overlap other nearby elements.
Explicitly sets the value of this property to that of the parent.
This value inverts the color of the outline to the opposite value of
the color "underneath" the outline to ensure proper contrast.
Sets the border to the indicated color value.
