CSS3 UI has reached CR. This means we can (and are encouraged to) drop the -moz-
prefix from the 'box-sizing' property.
Since quite a lot of sites rely on this property we should probably not remove
'-moz-box-sizing' but implement it like it was done with 'opacity'. (There is of
course the simple fact that lots of site authors were already using 'box-sizing'
because of Opera.)
Currently Mozilla supports 'padding-box' as a value, if we don't want to remove
that value, we should rename it to '-moz-padding-box', since it is not a valid
value according to the specification.

Since I don't have the ability to build and that will take some time before I
do I created a patch based on the 'moz-opacity' -> 'opacity' implementation.
It might be that I missed a few things, but like I said, I wasn't able to test
this.
Comment 2•21 years ago
|
||
1) I don't see a reason to create a DOM alias. box-sizing is not commonly
scripted, unlike opacity.
2) I'm rather opposed to throwing this switch unless some testing is done to
see how good our implementation is. In particular, I suspect that max and
min widths are broken (especially on replaced elements). In fact, I don't
see how the CSS2.1 algorigthm for min/max widths on replaced elements makes
sense as it stands in the presence of box-sizing. I've sent mail to
www-style to that effect. In any case, someone needs to start writing
testcases.
I suspect lots of stuff is broken and I'm opposed to the property in general. I
think we should not implement it.
Comment 4•21 years ago
|
||
Removing it altogether is fine by me.
Reporter | ||
Comment 5•21 years ago
|
||
Although I don't really like the property either, the 'calc()' proposal
discussed on www-style seems much better, /this/ is the property people are
using. I visit some fora quite often and this is what people are using to "hack
around" the box model differences.
This is also one of the solutions people are talking about and which is placed
on various webdesigner/webdeveloper resources. We can of course say they are
nuts for using this stupid property, but I don't think they will understand and
I don't think that we should break sites that are already using it.
I think this needs to be implemented (we should at least keep the
'-moz-box-sizing') and to do that we probably have to wait for W3C clarification.
Comment 6•20 years ago
|
||
I guess I'm one of the 'nuts'y people for wanting the ability to select between
box models, but the main reason why is that for the kind of web applications
that I'm building, 'content box' sizing is exactly the wrong kind of sizing I
need. I'm trying to do layouts that require 'border box' sizing. This is one
that Microsoft got right and the CSS committee got wrong.
In any case, there's no need to fight (or switch ;-)) - just give web developers
like me the choice via the 'box-sizing' property.
And *please*, if you're not going to implement this property, do *not* remove
-moz-box-sizing. Setting '* {-moz-box-sizing: border-box}' is the only way I've
been able to keep sane. My other stuff runs so well in Mozilla, but if I didn't
have border-box sizing, trying to lay out GUI would be a nightmare.
Cheers,
- Bill

It looks like box-sizing is dropped all together:

Please note that you are referring to a very out-of-date draft, CSS3 UI which
included this property as mentioned in comment 0 is a bit more recent.

IE 8 supports "box-sizing" now without prefix (Opera anyhow since 7.0). This should increase importance.
It would be a mercy for web authors and web compatibility to get this fixed soon.
Comment 10•15 years ago

My use case for this, for anyone who's interested in hearing it:
I've got a DHTML-based puzzle game. Some of its UI is the same no matter where the player is the game, while the rest is in several "screens" that get dynamically switched between. Now, for this game, different screens need to look different depending on what they need to present to the player; screens may need paddings of varying sizes and one of them doesn't need a border. But they all need to be the same size.
Ideally, I would write
.screen {
/* dimensions go here */
box-sizing: border-box;
}
and Mission Accomplished.
Comment 11•15 years ago

Sure, and right now you can write |-moz-box-sizing: border-box;|

Yes, as long as A. it doesn't get removed as per earlier discussion, and B. I repeat myself three times to ensure all major Web browsers listen to me. I'm a Web developer, not a leader of some snark-hunting expedition...

1. What QA can one help out doing to get this fixed?

That's what the whiteboard is saying so it is known ;)
I think it's too late for Firefox 4 but can we get it triaged for Firefox 5 ?
Comment 17•14 years ago
|

Florent, the property is not in CR. It's not well-defined how it should behave in many cases in the spec yet. Yes, some browsers dropped prefixes prematurely, but their implementations are not compatible with each other last I checked. So I wouldn't call this "well supported"....
Comment 18•14 years ago
|
||
And in particular, the interaction of box-sizing with replaced element sizing when max/min-width/height are used is still not defined.
Comment 19•14 years ago
|
||
Thanks Boris for this background information. I hadn't tested the different implementations beyond display:block (non-replaced) elements. And I obviously don't advise dropping prefixes prematurely.
Comment 20•14 years ago
|
||
Actually, it's been in CR for many years: css3-ui has been CR since 2004. The reason we haven't dropped prefixes is because there are some significant bugs with our implementation (see the dependencies).
Comment 21•14 years ago
|
||
Er, you're right that CSS3 UI defines box-sizing. But it doesn't define how it should work in enough detail that it can be implemented, leaving that to CSS3 Box, as far as I can tell...
But yes, we should fix the obvious dependent bugs, anyway, then create a decent test suite for this (which CSS3 UI certainly won't have otherwise).
Comment 23•13 years ago
|
||
The relevant part is not dropping the -moz- but correcting the behavior of min-height and min-width, as for now these ignore box-sizing, while other browsers apply to min-xxx the same rules as to xxx.

Niloy, we dropped the prefix for those because their implementations match the spec.
The implementation of -moz-box-sizing does NOT match the spec. See the bugs blocking this one.

There is one extremely important reason to drop the prefix even before fixing all issues with the current implementation - the technique of using:
* { box-sizing: border-box; }
has become popular recently (especially that some high-profile in web dev world people - as Paul Irish - has become advocating it) and if it's used for a mobile site, authors can easily forget about the prefix needed only for a browser with about 1% market share. And apart from most CSS3 features, not including a prefixed version of the property results not only in a minor degradation but in a completely broken site layout.
It would be interesting to know some stats about sites using border-box, especially on mobile. Nonetheless, this is something Mozilla should be wary about.

This blocks bug 850827 - Google have started using an unprefixed box-sizing on the Google Maps mobile site. I agree with this comment, it'd be really great to have this unprefixed, even if there are problems.

Just to note, desktop GMail also uses box-sizing, but only with a -webkit prefix, meaning we get spurious horizontal scrollbars in the 3-panel mode :( (I'll file a bug for evangelism)

Sure, I can look into this. Note that it's going to take a bit of time to determine the testing situation, and what we need to do to verify that our implementation matches spec. I will look into it in the next week or so.

Well, running a nightly or better yet a try build with the patch through the box-sizing test suite (which exists, right?) would be a good start....

OK, I've cloned the mozilla-inbound repo, build the OS X 64-bit debug build, run the test using:
./mach reftest layout/reftests/box-sizing/
then I applied the patch, re-run `./mach build` and then these tests.
All of them passed.
Anything else? :)

Looking in the csswg repo, I see no reason to believe that there is a test suite for any part of css-ui, fwiw.
Comment 44•12 years ago
|
||
> Anything else? :)
We obviously pass our own tests.
The question is whether our behavior sufficiently matches the spec to unprefix.
That requires either testing against the _spec_ test suite or verifying that our tests sufficiently match the spec and have sufficient coverage...

What Boris and Ms2ger are saying here is that there doesn't appear to be any tests in the CSS specification test suite, located here:
http://www.w3.org/Style/CSS/Test/
The css ui doesn't have any tests listed next to it, which indicates that there aren't any tests available for this spec yet. Probably as part of this bug, it might be a good idea to write some tests that should conform to the individual specification sections (see css3-multicol tests for an example).
Take a look here for more information on writing tests, too:
http://wiki.csswg.org/test/format
Comment 46•12 years ago
|
||
So, basically, we need to:
A) Construct tests that identify what the spec requires the behavior of box-sizing to be,
B) Verify our implementation passes these tests, and
C) Submit the tests to the W3C.
Comment 47•12 years ago
|
||
Hope dev will not mind this, since this patch passes FF own test suites and no W3C tests are available currently, I think real life testing by landing this patch in early FF24 Nightly cycle (which kicked in already) will be better if any site broken issues bugs filed against this, then it should be backout from next Aurora merger, all in all Nightly is bleeding edge test branch, so landing will not hurt. Just a suggestion..
Comment 48•12 years ago
|
||
The issue is not with whether sites are broken with the patch.
The issue is whether our implementation is broken enough that unprefixing it means we screw over web developers who then can't use the property.
Again, what needs to happen is checking what parts of the behavior are not tested and testing them. As a simple example, there are apparently absolutely no tests that test the interaction of box-sizing and the treatment of max/min-width/height on replaced elements with intrinsic sizes (read: images) that have nonzero paddings and borders.

The computed height is wrong in padding|border|(margin)-box model with window.getComputedStyle(object,null).height function.
That currently doesn't follow the box model.

Sorry for this bugspam, I've missed this codechange 1 month ago. I can confirm it works correctly on nightly with pagging|border-box model as well.
Comment on attachment 734251 [details] [diff] [review]
Patch v1
From a code perspective this patch looks fine, so r=dbaron on the code once we're ready to land it. But clearing review request to indicate that it isn't yet ready to land.
However, before it lands, as Boris said, we could use some additional test coverage of box sizing -- in particular, for the image scaling code. While the spec doesn't define precise wording, we should ensure that all the image scaling cases yield the same results for the same *specified content box width/height*, whether that width/height was specified directly or whether a larger width was specified and padding-box or border-box box-sizing was used.
I thought we had a bunch of tests for the image scaling code somewhere that could be modified to test this, but I can't find them. That doesn't mean they aren't there, though.
Attachment #734251 -
Flags: review?(dbaron) → feedback+
I think the test I was thinking of was https://test.csswg.org/suites/css2.1/20110323/html4/replaced-min-max-001.htm
So a good start would be converting that to reftests (which I think may already be done somewhere), then adding variants with padding, border, and margin, and then adjusting those variants for different values of box-sizing to make sure that changes that don't change the specified content-box widths/heights don't change the size of the box.

Is there any reason other than comments #3-5 why this bug can't be shipped in either 23 or 24?
There are no longer issues with this bug. There aren't many test cases. I suspect you cover over 99.9% of all cases with your implementation at least. Wouldn't it be easier to just ship it now and let people file bugs as the happen?
You already shipped the flexible box model in spite of the fact that the implementation is incomplete (IE flex-wrap:wrap). As a developer I can't stand vendor prefixes. This is the only prefixed property I use anymore (webkit included).

Allen, please do read the whole bug; this is discussed at length starting in comment 44.
Comment 58•11 years ago
|
||
Believe me I have read the whole bug. I've been following this bug for 2 years at least.
I'm suggesting that any issues with the implementation are minor and it will be easier to find them by shipping now rather than trying desperately to create tests that will aim at the odd aspects of the spec. If you look at comment 45, he said that there doesn't seem to be any tests for this part of the spec.
The last couple of bugs that were blocking this were all minor. The image padding bug for example, I never encountered it and after I checked out that bug I had no problems creating a work around.
I only mentioned comments #3-5 because the very people that said they didn't want to implement this part of the spec are the same people that seem to be delaying it for looking for non-existent tests. In other words this is being delayed for political reasons rather than technical.
Comment 59•11 years ago
|
||
I think the issue is that for flexbox we knew in what ways it didn't match the spec and we agreed those were minor enough to ship.
The problem here is that we don't even know what's broken; once we do we can decide whether it's minor...
Comment 60•11 years ago
|
||
That's kind of my point. You don't know and you won't know what's broken.
If you were to ship now I can only see 3 things happening.
1) A website doesn't use box-sizing at all and shouldn't be affected
2) A website only uses non-prefixed box-sizing and is currently broken as a result (may or may not be fixed by shipping this patch)
3) A website uses the -moz- prefix in addition to being non-prefixed and either works or doesn't, but shipping this bug wouldn't change that.
A 4th scenario involves -moz- prefixing only, but that would only break if you removed the prefix rather than just not requiring it.
One commonality you'll notice in my scenarios is that anything that would be broken by shipping this is already broken anyway.
From what I've read here there are no tests and therefore this bug will continue to rot for another 10 years and you'll never know what is actually broken.
At the very least you should consider making a preference to enabling box-sizing unprefixed (personally I would rather skip that). That will at least allow us to actively search for websites that are broken under the implementation. As of right now there are websites that are broken by not shipping this patch as is, in fact you have 2 of them listed as blocked bugs. Maybe they have additional issues and maybe they don't, but you won't know until you ship this.
Comment 61•11 years ago
|
||
> 3) A website uses the -moz- prefix in addition to being non-prefixed and either works or
> doesn't, but shipping this bug wouldn't change that.
Assuming they use the same value for the two properties.
But the real issue with unprefixing broken crap is not site breakage today but causing issues for web developers tomorrow.
> there are no tests and therefore this bug will continue to rot
No, what will happen is that someone will step up and write tests. Worst case, the spec will need them anyway, so they will happen much sooner than 10 years from now.
Comment 62•11 years ago

Actually there are only 3 possible values. border-box, padding-box, and content-box. Firefox is the only vendor that supports padding-box. content-box is the default and is implemented automatically. That leaves border-box, so no that argument is invalid.
As a web developer myself I'm telling you right now you are causing more problems by NOT unprefixing it than the .0001% odd cases that MIGHT crop up as a result. The web developers of tomorrow are almost universally using it RIGHT NOW. Most of them develop on webkit. You are the ONLY vendor that doesn't support this. I can't tell you how many times I see webkit only prefixing (without the W3C version) in code. That's a problem in itself, but by eliminating as many vendor prefixes as possible, it minimizes the requirements to get things working in firefox. I'm also beginning to see people implement this as * { box-sizing:border-box; } (in other words firefox isn't supported) This is a MUCH bigger problem than a couple minor issues cropping up.
Why is it ok for IE (ironically I believe they were the first to support it), chrome, safari, and opera to do this a long time ago if they don't have any tests? It's obviously worked out for them. I can promise you that any odd issues that might crop up aren't worth the delay because you will fix more problems than you create.
The real problem you guys had was lack of support for min/max values as well as table support. That's been fixed for a while. One day out of the blue, the SVG bug disappeared, which was minor, as well as the image padding issue, which I had a work-around.
Comment 63•11 years ago

So, I've got some tests in my patch repository I've been working on. I should have them ready to post shortly. They might need some tweaking to get into W3C format.
One thing I've noticed, though, is that webkit and opera don't seem to implement box-sizing for replaced elements. More specifically, the test in comment 54 that dbaron mentioned doesn't seem to be different with opera (I think I still have an old presto version) or chromium when I add padding to the images and then specify box-sizing: padding-box (or -o-box-sizing: padding-box or -webkit-box-sizing: padding-box).

Ah, you know, it might be just that webkit/presto don't implement padding-box...

Afaict, IE 10 doesn't implement it either. If I remember correctly, 'padding-box' is a recent addition to the spec. And it is marked as 'at risk'.

We should probably have tests for these, though. Even if no browser pass the tests, it would be useful for future conformance.

Or if no other browser cares to implement it, maybe it should be removed from spec and Gecko... (let's have this discussion in a different place if interested)
Comment 69•11 years ago

Finished tests for box-sizing, but there seems to be a slight problem on some platforms where the p element in box-sizing-replaced-{001,002}.html (by looking at it using the inspector) in example 1 below produces a box with a slightly larger height (~4px) than the <p> element in box-sizing-replaced-{001,002}.ref.html. I'm still analyzing why this is going wrong.
The devtools inspector shows that there are no margins or padding, and if I set the line-height to be the same on both <p> elements, or turn off margins and padding globally using the * selector, it has no effect. Basically, the problem comes up on OSX platforms - there's about a 4px gap between the top line and the bottom line (e.g. in https://tbpl.mozilla.org/?tree=Try&rev=2f1c02122c4f ) that isn't there in the reference images.

So what's needed to breath life into this bug again? Tests?
Comment 72•11 years ago
|

I still think if the people at mozilla didn't hate it, it would be implemented by now. Just look at the comments at the beginning of the page. I don't get the hate for it. And contrary to their comments I feel that while calc() is great, there are many cases where border-box is far superior. I use both where I feel appropriate. I just think its embarrassing that -moz-box-sizing is the only prefixed code I have left.
I may not like chrome, but I'm happy that they said they will never prefix anything else and plan to remove all prefixes. I just hope they actually kill them too. I don't ever want to see -webkit-border-radius again especially if its implemented. I wish Mozilla would adopt the no prefix policy as well.

box-sizing-tests
In general, could you use "-ref" in filenames rather than ".ref"?
(Should be easy to fix by search-replace on the patch.)
The test files (but *not* the -ref files) need at least a <link
rel="help" pointing to the relevant section of the spec, which is
presumably http://www.w3.org/TR/css3-ui/#box-sizing . A
<meta name="assert"> describing what the test is trying to test
wouldn't be a bad idea, either.
I think the box-sizing-content-box tests (not references) should use
percentages just like the box-sizing-padding-box and
box-sizing-border-box tests. Otherwise they're just testing the initial
value of the property, which is tested well enough by
property_database.js-based tests.
box-sizing-padding-box-003.ref.xht (the reference!) probably should
have set widths/heights rather than using min-width/min-height, so
that it tests that min-width/height are working correctly a little
better.
box-sizing-replaced-* should probably mention in a comment at the
top that they're derived from replaced-min-max-001.
I don't understand why #img1 is so much simpler in your test than the
test you derived it from -- could you use the same test?
I'm also not convinced that the tests are all still testing what they
are supposed to at the new sizes. My intent was that you'd still
produce a test that was leading to 75x75 images, but you'd increase the
numbers in the tests (which is using padding-box/border-box) to account
for the padding/border. (Instead, you decreased the numbers in the
reference so all the images are smaller, but that means thet math that
was worked out to ensure all the combinations were tested isn't
*necessarily* valid anymore, though it might still be true.) I think it
would be better to have 75x75 results, and increase the numbers in the
test file rather than decreasing them in the reference. (And the
references should just be able to use width:75px and height:75px for
*all* the images rather than having min-width/max-width at all.)
I think these are good with those things fixed, but I'd like to take a
quick look at the box-sizing-replaced-* tests after those changes, so
marking as review-. But thanks for writing these, and sorry for the
delay getting to the review.

Oh, and if you happen to have the replaced variant for content box sizing, that would be useful to have as a reftest if we don't already.

I did both of these, but you may want to review my wording for the <meta name="assert"> tags.

Fixed, although, I noticed that the replaced-min-max-001 is flagged as having problems in the CSS test suite (#48 under "48 Untestable Reftests": http://wiki.csswg.org/test/reftest )

Yes, I modified this.

Ok, I reworked all of the tests so that the height/width is adjusted such that it takes into account the padding/border in such a way that the image remains 75x75.

I added another test, box-sizing-replaced-003, which tests the box-sizing: content-box attribute. This is essentially the same as the replaced-min-max-001 that was in the w3c test suite. We have it in our tree under layout/reftests/bugs/234686-*.html, but these are individual tests rather than a larger set of 10 images in one page. I'm not sure if we want to duplicate the tests, so I added the new test for your perusal. Just let me know if you want to remove it. I guess it still tests to make sure that the -moz-box-sizing: content-box value is being processed correctly.

Instead of:
>+ <meta name="assert" content="The box-sized elements should each take up 1/2 of the horizontal space of the containing element, including their borders and padding." />
it would probably be better to write something like:
>+ <meta name="assert" content="-moz-box-sizing: border-box should make the element's (percentage) width be the distance from the left border edge to the right border edge." />
and similar for the other tests. In other words, describe the feature
being tested rather than exactly what the test shows.
In box-sizing-replaced-001.xht, change:
#img1 max-width from 175px to 115px
#img2 min-height from 60px to 70px
unless I'm missing a reason they should be as they are.
same for box-sizing-replaced-002:
#img1 max-width from 185px to 125px
#img2 min-height from 60px to 80px
same for box-sizing-replaced-003:
#img1 max-width from 165px to 125px
#img2 min-height from 50px to 60px

Just a word of encouragement guys. I don't do anything particularly complicated replacing elements (reading this thread briefly it seems to be the sticking point as I understand it).
But.
I've been using:
-moz-box-sizing:border-box;
box-sizing:border-box;
Without issue, for months and months now. Love this property for various reasons e.g. for making input and select the same width in a responsive design, it is saving me plenty of time and my sanity.
Keep up the good work, I hope we can resolve the final issues and drop the prefix soon.
The only thing I want more from FireFox is flex-wrap.

This patch makes the changes noted in comment #78.
It uses the exact wording you made, with just padding, border, and content words switched out depending on the test.

So just "element's width"?

It would be pixels, right?
Also, shouldn't the tests use box-sizing instead of -moz-box-sizing?

pixels are a type of length; the point here is that we have a length test and a percentage test, so it's better to say length

A basic search on GitHub:
https://github.com/search?q=box-sizing%3A+border-box&ref=cmdform&type=Code
shows that `box-sizing: border-box` is used very often and very few people add a `-moz-` prefix to the list.
Now that all the hard work has been done (thanks a lot for that!), there are no hanging critical bugs, tests have been written etc., can we get this into Firefox 29?

I don't know. At a minimum we'd probably want to move them to the layout/reftests/w3c-css/submitted/ directory. But there might be a bunch of other issues raised by the code that checks them when they get submitted to the w3c repository.

The last patch was step 1. This patch takes care of step 2. However, I'm not sure that I was supposed to change files in the following directories:
browser/extensions/pdfjs
layout/reftests/w3c-css/submitted

The tests in layout/reftests/w3c-css/submitted were actually the primary subject of "the tests" I was talking about in part 2.
The other patches are good, but it's probably worth splitting them into multiple patches for different reviewers to look at. In particular, I'd split them up as:
* browser/extensions/pdfjs (r? to :bdahl)
* rest of browser/ and toolkit/ (r? to :gavin or similar... who might ask for it to be split further)
* mobile/android/ (r? to :mfinkle or :margaret or similar)
* content, dom, layout, widget (r? to me)
and skip these changes, which shouldn't be touched since they're imported code:
* testing/xpcshell/node-http2/
It's probably worth filing a separate bug for this, and marking this bug as fixed.

If you do make this a preference setting, please consider defaulting it to enabled.
The preference would be a preference for the prefixed -moz-box-sizing (not the unprefixed box-sizing), defaulting to enabled, so that authors can test their sites in advance of our dropping support for the prefixed version. See http://dbaron.org/log/20130225-removing-prefixes

https://hg.mozilla.org/integration/mozilla-inbound/rev/13f6dad08f3a
We should probably close this bug and do the substitution of our own code in other bugs (i.e., continue from attachment 836570).
Whiteboard: [parity-IE] [parity-opera] [parity-webkit][leave open] → [parity-IE] [parity-opera] [parity-webkit]
And test updates imported in http://hg.csswg.org/test/rev/2aa42c3a4da5

I'm not sure we really _need_ uplift for the preference thing. Not uplifting it just means that in 29 both the prefixed and unprefixed form will be supported unconditionally, which is not fatal. Starting with 30 people will be able to experiment with the removal of the prefixed form. So all it'll really do is delay when we can remove the prefixed form by that one release cycle.
On the other hand, uplifting that patch won't hurt anything either; it's pretty simple...

I've created bug 968029 for this purpose.
Comment on attachment 8365750 [details] [diff] [review]
Bug 243412. Use unprefixed box-sizing internally
cancelling this review request since this is now happening in bug 968029 (as described in comment 107)

It's probably better not to uplift the preference, since if anyone tried it, the browser would end up somewhat broken (lacking the fixes in bug 968029).

We should probably just resolve this as FIXED, then.
Yep.
Also setting assignee to one of the many people who helped get this code in.
