Anticipated spec changes

Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).

he CSS spec is still in early stage, it may be renamed, or the value may be moved to other properties, in that case, we may want to keep the current syntax for a while.

I don't think this should ship until the relationship between white-space and text-wrap is fully resolved and implemented. That just seems like a bad idea. I don't think it will be difficult or time consuming, but I think it needs to be done.

Also, as the editor of the spec, I'd also be interested to know if any specific aspects of the `text-wrap: balance` definition need improving, now that there's some implementation experience... Relatedly, from an authoring perspective, will this be sufficiently useful without any integration into intrinsic sizing? Does it actually solve the problems authors want it to solve, or is there something still unsatisfied here? Do we have any real feedback on this from the prototype?

Lastly, there had been some discussion about more control over the length of the last line, having it be not just "anything" or "same as the rest of the paragraph" but things like "at least 4em" or "at least 15% of a full line". Doing something like that would split this control into its own independent property, rather than being a keyword on `text-wrap`. Has there been any investigation in that direction? Are we sure we don't want to go there?

I don't understand what issues you might be thinking of. white-space
has effects on wrapping, yes, but text-wrap:balance is just using the
wrapping algorithm, *whatever* it is, and choosing different wrap
opportunities (as if the box was slightly narrower, generally) than it
would otherwise have.

If you think there are specific issues that need to be fixed (that
don't equally need to be fixed for text-wrap:wrap), could you list
them?

I'll let Koji provide more detail, but the only thing I'm aware of is
that the "10 lines" limit the spec currently allows for bailing out
appears to be too large. I think our initial implementation is bailing
on >4 lines.

We probably do want some type of control for orphan words, but it's an
unrelated problem; *all* of the text-wrap options can want it. Likely
it belongs in its own property.

The 'text-wrap' property is a longhand of 'white-space'. If you don't
implement it as such, the way that 'text-wrap' and 'white-space' declarations
override each other will change if/when you do.

This intent to ship just says that you will ship 'text-wrap'. It doesn't say
that you will also implement 'white-space-collapse' (the other longhand of
'white-space') or the shorthanding relationship between 'text-wrap' and
'white-space'. I therefore assume you're shipping 'text-wrap' as an
independent property, and this is not going to be spec-compatible.

How is (a hypothetical) 'last-line-length: 100%' different from 'text-wrap:
balance'? If they're the same, does it make sense to have 'text-wrap: balance'?

They're quite different. A balanced paragraph can very easily have the
last line *not* fill 100% of the line box, because being balanced
actually means averaging an 80% fill, for example; there's no way to
predict what the ideal fill is in a whole-para balance. There's also
perf concerns - a last-line control might very reasonably only try to
adjust the last several lines, rather than the entire paragraph, so
that it's generally usable on all text rather than just text short
enough to be efficiently whole-para balanceable.

Hi Koji,

Looks like the tests are in https://wpt.fyi/results/css/css-text/white-space?label=master&label=experimental&aligned&view=subtest&q=balance. There's one failing test there, do you know why that is? And overall, are you happy with the test coverage here, does it cover most important corner cases?

Best regards,

Philip

We have implemented a similar approach as the vertical-align/baseline-source case so that setting the `white-space` resets the `text-wrap: wrap`. The current impl passes this cascading test.

Looks like the tests are in https://wpt.fyi/results/css/css-text/white-space?label=master&label=experimental&aligned&view=subtest&q=balance. There's one failing test there, do you know why that is?

Thanks for pointing this out. The test passes in Chromium repo, I'll investigate why it fails in wpt.

 And overall, are you happy with the test coverage here, does it cover most important corner cases?

I'm keeping eyes on incoming issues and feedback. It's a pleasant surprise that more web devs than expected are excited with this feature, and gave us great feedback such as this test results. Paragraph-level line breaking is a new area for browsers, there should be more rooms to improve further and I'm looking into them, but I think it's at a good quality to ship, and we can expect more feedback for the next stage.

Yeah there seems to be a lot of excitement for this feature, which is great! I think you're saying that the test coverage in WPT is good, and there aren't any known missing areas that you're aware of, is that right?

It turned out that the build in the wpt is DEV, not Canary, so it should turn to green soon.

Yeah, this is a known problem, because there is no Chrome Canary on Linux, so Chrome Dev is the most frequently updated official Chrome binary we can use.

We have implemented a similar approach as the vertical-align/baseline-source case so that setting the `white-space` resets the `text-wrap: wrap`. The current impl passes this cascading test.

This mitigation makes sense to me and I think it's sufficient. In the case of the intent you're linking to here, vertical-align is specified to be a shorthand of baseline-source, and after feedback about the issue on that intent thread, Ian implemented a mapping from existing supported uses of vertical-align to baseline-source. And Koji implemented the same approach for white-space, which is specified to be a shorthand of text-wrap.

Just as with the other intent, there are other possible compat risks; in addition to some mentioned in the other intent thread, there is this CSSWG issue discussing it. But I don't think we have any information leading us to conclude that the risk analysis we performed for baseline-source differs from the one we're discussing here, so I don't consider these concerns blocking shipping text-wrap.

[Philip Jägenstedt]

LGTM2, it sounds like the compat risk described in https://github.com/w3c/csswg-drafts/issues/8398 prevents making the shorthand/longhand relationships exactly per spec, but that we're taking the same approach here as for baseline-source.

The current impl passes this cascading test <https://github.com/web-platform-tests/wpt/blob/69982c63f5/css/css-text/white-space/text-wrap-white-space-001.html>.

That test doesn't cover the interaction of other values of `white-space` with
the `nowrap` value of `text-wrap`. It would be incorrect for e.g.
`white-space: pre` to return `text-wrap: wrap`.

I think it would be better to just implement both longhands of `white-space`
properly.

I'm not concerned about the quality of the balancing, as I'm sure it's fine,
and it will improve over time... my concerns are mainly with
a) interaction of the properties
b) any layout interactions with e.g. floats, initial-letter, positioning, text
justification, box sizing, etc.
c) whether the CSSWG considers this stable enough to ship, or if there are
unresolved concerns about the design of the feature

I'll note that there was an issue filed in the CSSWG repo recently in response
to the Blink implementation:
https://github.com/w3c/csswg-drafts/issues/8516
and it raises questions about sizing and floats, among other things.

Implementing `nowrap` and other values is easy but it creates other new compat risks that are more difficult for authors to handle. With the current impl, authors can detect the situation by `supports(‘text-wrap: nowrap’)`.

I understand that the spec is still in early draft, it’s WD, not CR, PR, nor REC. If the spec changes, we can change our implementation accordingly. Even if names were changed or the feature was dropped, not applying `text-wrap: balance` doesn’t cause disasters; it just lays out the same as other browsers. Also, the NYTimes article says it detects the support of `text-wrap: balance`.

The #8516 you cited above has some initial feedback. Also I will share any feedback we get with the WG and I look forward to discussing them. If spec changes from the discussions, as I stated above, we’re willing to match the new spec. 

[TAMURA, Kent]

LGTM3.

  - The shorthand issue can be addressed separately.

  - The maturity of the specification is a risk. But it seems the risk of behavior changes after shipping would be small.

Can you outline these new compat risks that only apply to `nowrap`? Also, are
they filed as an issue against the CSS spec? If there is a real compat risk to
implementing the spec, then the spec needs to be changed.

Note that if the spec changes to not have a shorthanding relationship due to
compat risks, then that means your implementation would need to change to stop
faking a shorthand relationship also.

Going back to that first quoted point: you are currently not testing the value
of `text-wrap` when `white-space: pre` has been declared. If you are returning
`text-wrap: wrap` rather than `text-wrap: nowrap`, then we have a problem,
because that is not compatible with what the spec requires.

Since you think this is the correct thing to do, can you explain why you think
it is better for Blink to ship a behavior change in the future (to match the
spec) vs. shipping the correct behavior initially?

Btw, I notice you are only testing the shorthanding side-effects you have
carefully faked in your code, rather than all of them. I know it's natural to
only write (passing) tests for things you've specifically implemented, but it
is misleading... because if Blink intends to ever follow the spec, there are
property interactions here that will noticeably change. And your reviewers
should be made aware of that.

> With the current impl, authors can detect the situation by `supports(‘text-wrap: nowrap’)`.

I don't understand what this suggestion is solving.

As far as I understand, once Blink ships something, whether it is willing to
change its implementation generally depends on the usage rates of the new
feature. So if Blink ships the feature, and it is widely used, then Blink
would be unwilling to change or drop the feature. Does that not apply here?

Also, why not ask the CSSWG about (c)?

The reporter was agreeing specifically with adjusting the limit to 4 lines
rather than 10, not with anything else. Some of the other points brought up by
the reporter include:

* Interaction with `text-align` (which you seem to have fixed)
* Interaction with floats (no tests in WPT)
* Interaction with `initial-letter` (no tests in WPT)
* Interaction with intrinsic sizing (not seriously discussed, but imho one of
the most important questions that would have been worth investigating with the
prototype)

I also asked some specific questions inline, so let me quote them in list form
since they seem to be repeatedly overlooked:

* Will this be sufficiently useful without any integration into intrinsic sizing?
* Does it actually solve the problems authors want it to solve, or is there
something still unsatisfied here?

> Also I will share any feedback we get with the WG and I look forward to

I think it would be useful to know if you have positive feedback from web
developers who have tried to incorporate it into actual designs, or if you
only have feedback that developers are “excited about something like this” but
have not experimented enough to think about important details that might
matter to them (like the interaction with intrinsic sizing).

> If spec changes from the discussions, as I stated above, we’re willing to match the new spec.

You say that, but you're not even willing to match the spec in terms of
shorthanding... :/

Here's a few examples I've seen where not just developers getting excited about the single LOC they need to add for better results, but the designers on their teams wanting it after seeing it within the context of their design systems. Here's a couple example of teams trying it out in their design systems, with positive things to say (if lots of drooling are good signals) about the results:

Example #1:

Before:

I am very supportive of this feature being worked on, but I am very puzzled by Google's intent to ship something that is different from the spec. It doesn't seem that you have expressed any disagreement with what the spec says, or asked for it to be changed. If you think the spec's design is wrong somehow, the CSS-WG needs to be made aware of that, so that we can look into your feedback and address it accordingly. If you think the spec's design is right, then why take the risk to ship something subtly incompatible with it, which could cause a compat problem that will eventually prevent you (and everyone else) from shipping the thing we (apparently) agree is right?

Thanks for these examples, I think they show that intrinsic sizing interaction
isn't necessary for this feature to be useful. :) Which is good, because
addressing that request would be hard.

(It's been a request that comes up in general for text wrapping, but
`text-wrap: balance` makes the difference between our current intrinsic sizing
and true shrinkwrapping a lot more dramatic.)

agree, those are the times when balanced wrapping is undesirable, where manual placed <br>'s still have an advantage because they will shrinkwrap. 

manual <br>s wont help here, but like within a card, balance is not great because the intent to balance actually imbalances the design. see the below image, example on right is balanced but actually feels unbalanced.

def not a show stopper, but i would like to see a CSS property to help authors articulate the desire to shrink wrap. here's a demo i made showing the problem space of wrapping not shrink wrapping.
