Tips and Notes
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.
Browser Support
The numbers in the table specify the first browser version that fully supports the property.
| Property | ||||||
|---|---|---|---|---|---|---|
| outline-style | 1.0 | 12.0 | 8.0 | 1.5 | 1.2 | 7.0 |
Note: IE8 supports the outline-style property only if a !DOCTYPE is specified.
