Definition and Usage
The outline property sets or returns all the outline properties, in a shorthand form.
With this property, you can set/return one or more of the following (in any order):
- outline-width
- outline-style
- outline-color
An outline is a line around an element. It is displayed around the margin of the element. However, it is different from the border property.
The outline is not a part of the element's dimensions, therefore the element's width and height properties do not contain the width of the outline.
