Remarks

Displaying an outline does not cause reflow, no matter how wide the outline is. The outline frame is drawn over an element, and does not influence the position or size of the box, or of any other boxes.

Windows Internet Explorer places the smallest contiguous outline around all elements or shapes that have an outline. Therefore, an outline may be non-rectangular if different sized elements or shapes are grouped together.

Windows Internet Explorer 8 and later. The outline property is supported in standards-based document modes. For more info, see How to Enable Standards Support.
