Definition and Usage

An outline is a line that is drawn around elements (outside the borders) to make the element "stand out".

The outline-width specifies the width of an outline.

Note: Always declare the outline-style property before the outline-width property. An element must have an outline before you change the width of it.

Default value: medium
Inherited: no
Version: CSS2
JavaScript syntax: object.style.outlineWidth="thin"

Browser Support

Internet Explorer Firefox Opera Google Chrome Safari

The outline-width property is supported in all major browsers.

Note: IE8 supports the outline-width property only if a !DOCTYPE is specified.

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.
