css outline-width property syntax

Function:Set the width of the entire outline of the element.

Note:This width will only work if the outline style is not none. If the style is none, the width is actually reset to 0. Negative length values are not allowed.

Note:Always declare the outline-style attribute before the outline-width attribute. The color of an element's outline can only be changed after it has obtained its outline. Contours do not take up space and are not necessarily rectangular.
