2.2.67 [CSS-Level2-2009] Section 18.4, Dynamic outlines: the 'outline' property

V0292:

The specification states:

The outline created with the outline properties is drawn "over" a box, i.e., the 
outline is always on top, and does not influence the position or size of the box, 
or of any other boxes. Therefore, displaying or suppressing outlines does not cause 
reflow or overflow.

Quirks Mode and IE7 Mode (All Versions)

The outline property is not supported.

All Document Modes (All Versions)

Outlines are drawn underneath positioned descendants.

V0293:

The specification states:

Outlines may be non-rectangular. For example, if the element is broken across 
several lines, the outline is the minimum outline that encloses all the element's 
boxes. In contrast to borders, the outline is not open at the line box's end or 
start, but is always fully connected if possible.

Quirks Mode and IE7 Mode (All Versions)

The outline property is not supported.

V0294:

The specification states:

The 'outline-color' accepts all colors, as well as the keyword 'invert'. 'Invert' 
is expected to perform a color inversion on the pixels on the screen. This is a 
common trick to ensure the focus border is visible, regardless of color background. 
Conformant UAs may ignore the 'invert' value on platforms that do not support color 
inversion of the pixels on the screen. If the UA does not support the 'invert' 
value then the initial value of the 'outline-color' property is the value of the 
'color' property, similar to the initial value of the 'border-top-color' property.

Quirks Mode and IE7 Mode (All Versions)

The outline-color property is not supported.

V0295:

The specification states:

This specification does not define how multiple overlapping outlines are drawn, or 
how outlines are drawn for boxes that are partially obscured behind other elements. 
Note. Since the outline does not affect formatting (i.e., no space is left for it 
in the box model), it may well overlap other elements on the page.

Quirks Mode and IE7 Mode (All Versions)

The outline property is not supported.
