outlinecreates a border outside the element’s area, not adding to its width and not influencing the surrounding layout. From the quirksmode.org page onoutline:That is a very useful feature indeed, because it allows e.g. highlighting an element on
hover/focusactions without disturbing the neighboring elements. The slight dotted outline around focused links in Firefox is done using theoutlineproperty.It’s not supported by IE < 8, though, so it’s only of limited everyday use.
