Expression Studio 4.0

Sets the width of the outline frame.


{outline-width: sWidth }

Possible values


String that specifies or receives one or more of the following values:


Default. About 4px.


Less than the default width.


Greater than the default width.


A floating-point number, followed by an absolute units designator (cm, mm, in, pt, or pc) or a relative units designator (em, ex, or px).

This property has a default value of medium. It is not inherited.


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.
