Outline: solid, dashed, dotted
Set the type of pen used to draw an element's outline ("outside-the-box" border).
Unlike many other similar properties, the outline-style property does not have corresponding top, right, bottom and left properties. Outline-style rules can only be set for all four sides at once.
Specify the outline style using any one of these keywords:
|auto||Use the browser's default for this property|
|none||Do not display an outline|
|dotted||Use a series of small dots for the outline|
|dashed||Use a series of short dashes for the outline|
|solid||Use an unbroken line for the outline|
|double||Use two parallel unbroken outlines (|
Or choose one of these special effects when
outline-width is at least 2px):
|outset||A raised content appearance is created by adjusting the bottom and right edges to be slightly darker|
|inset||A sunken content appearance is created by adjusting the top and left edges to be slightly darker|
|groove||A raised border is created by adjusting half of each edge to be slightly darker|
|ridge||A sunken border is created by adjusting the opposite halves of each edge to be slightly darker|
