Definition and Usage
An outline is a line that is drawn around elements, outside the borders, to make the element "stand out".
The outline-style property specifies the style of an
outline.

Tips and Notes
Note: Outlines differ from borders! Unlike border, the outline is drawn outside the element's border, and may overlap other content. Also, the outline is NOT a part of the element's dimensions; the element's total width and height is not affected by the width of the outline.
Browser Support
The numbers in the table specify the first browser version that fully supports the property.
