6647 - (css2outline) CSS2 'outline' property

Status: VERIFIED DUPLICATE of bug 281972

(Core :: CSS Parsing and Computation, enhancement, P3)

Description

[Hixie (not reading bugmail)]

The CSS2 outline property would allow widget focus to be drawn using
spec compliant methods.

There is a test page here:
   http://www.bath.ac.uk/%7Epy8ieh/internet/eviltests/outline.html

See bug 1859.

[Peter Linss]

The property data is ready for use in the style context.

Reassigning to Pierre.

Moving all Widget Set bugs, past and present, to new HTML Form Controls
component per request from karnaze.  Widget Set component will be retired
shortly.

Comment 5

[Kevin McCluskey (gone)]

This should be implemented for frames in general. It is not a form element
specific bug. The CSS border rendering code needs to be modified to include
support for rendering the outline border.

Verified dup of #9816

[Blake Ross]

Since bug 9816 turned into the 'remove CSS2 for FCS' bug, and is already 
littered with comments, I think we should make this the bug for FUTURE support 
of the 'outline' property.

Ian's comments from bug 9816 about remaining issues:

1. It appears that we don't support 'dotted' and 'dashed' outline-styles at all.
   This is wrong, IIRC we should treat them as 'solid' if we are not able to
   actually treat them as dotted or dashed styles (BUT I MAY BE WRONG THIS NEEDS
   TO BE CHECKED!!!).

2. We do not appear to support the 'invert' outline-color.

3. We have major drawing errors with inset and outset outline-styles.

4. We have some odd, annoying repaint problems (as I understand it, this is
   quite a major problem code-wise). This is bug 9809, marked Future, mostfreq.

5. We interpret 'groove' and 'ridge' the wrong way round.

6. We do not support outline on inline elements (the main use of outline!!!)

7. We draw the outline in the wrong place (as far as I can tell?).

8. According to bug 22892, we don't do 'outline' on XUL -- which I would 
   guess is one of the major uses of outline as far as we are concerned

Nominating this bug for nsbeta1 on behalf of [e-mail].

Comment 13

[Matthew T (active 1999-2002)]

--> Style System (which may not be correct, but this sure ain't a Form Controls bug)

Comment 14

[Kevin McCluskey (gone)]

To implement we would need to be able to draw to the outside of the frame. This
would require some major modifications.
Marking nsbeta1-.

Assigning pierre's remaining Style System-related bugs to myself.

Comment 16

[Jerry Baker]

Just curious: why does -moz-outline work, but the standard outline does not?
They have the same effect as far as I can tell.

Comment 17

[Jacek Piskozub]

Jerry: The reasons are listed in comment #9. This feature is just not ready for
the prime time. 

Sorry for the spam.

9. We don't merge outlines for inline elements correctly (bug 133165)

Comment 22

[Sekundes]

seems like the current -moz-outline is rendered inside the border but the web
standards outline property should be rendered over the border.

Comment 23

[Felipe]

It's worth pointing out that this property is in the default HTML 4.0 stylesheet
(*:focus). Hence, Moz should support it at least enough that a designer can
manipulate the default setting or turn it off.

Comment 25

[Aaron Leventhal]

-moz-outline-offset is now implemented
Negative offsets are allowed

Comment 26

[Robert O'Callahan (:roc) (email my personal email if necessary)]

I think we're ready to turn this on with the real 'outline' name. I will write a
style system patch to do that.

Comment 27

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

See bug 93156 for the aliasing stuff I did for -moz-opacity, which you'll want
here as well, I suspect.

It looks like Mats did this in bug 281972.

Comment 29

[Robert O'Callahan (:roc) (email my personal email if necessary)]

Yep. Thanks mats!
