CSS outline properties

The CSS outline properties draw a border around an element that does not affect layout, making it ideal for highlighting. This covers the outline shorthand, as well as outline-width, outline-style, outline-color and outline-offset.

Firefox also supports the non-standard -moz-outline-radius property that acts similar to border-radius.
