Involves gamma correction amongst other causes. We've experimented with some APIs but we haven't got improvements in all cases 16:25:03 ...: I don't think there's an implementation solution for this.

Can cause lots of jitter in lots of cases. I don't think it's a good solution 16:28:41 ...: Suggestion: pick one position, and that position has to stay constant, [...] 16:28:54 fantasai: MS Word changes the position of the underline with every change in font styling 16:29:02 ...: and vertical align switches 16:29:13 glazou: yep, I just tried in Word on Mac 16:29:40 SteveZ: I support your position that the underline ought to be calculated for the whole stretch... but how much is the strikethrough problem an issue in reality 16:30:13 fantasai: for people trying to use HTML as a word-processor format, the visual results are undesirable 16:30:24 glazou: the usual rendering for DEL is strike-through 16:30:33 glazou: it's probably not too common 16:30:41 s/common/uncommon 16:30:58 TabAtkins: Suggestion is reasonable 16:31:04 fantasai: because WYSWYG editing results in two nested elements, and it's a problem if the outer element is carrying the line and font size changes on the inner one 16:31:10 SteveZ: It'll be hard to get interop, so bugs would be filed 16:31:36 fantasai: I don't think the threshold would handle vertical alignment though. I think you'd have to ignore vertical alignment when doing these things 16:32:10 fantasai: One of the problems with an overline is that if the font-size increases then the overline looks like a strike-through 16:32:16 ...: need intelligent averaging 16:32:31 ...: the problematic case seems to be immediate nesting; that case is solved by averaging 16:32:47 glazou: What about overline? The original usecase? 16:33:03 fantasai: the overline looks like a strike-through, which is a problem 16:33:31 glazou: what do you want to overline? the whole element, or the characters inside? Is there one overline for the whole thing, above the highest thing? Or one per sub-element? 16:33:52 fantasai: neither. If the elements don't change size much; you want a common line. If there is, then the line should break 16:34:12 glazou: I tend to agree with the proposal 16:34:15 TabAtkins: yes 16:34:28 fantasai: So, how do you implement and test the proposal? 16:34:46 TabAtkins: I don't see the problem. [...] 16:35:01 SteveZ: Must define it with an understanding that there can be hanging fonts 16:35:04 I think any automatic behavior is going to be inadequate. underline-offset and underline-weight, etc. would be the way to solve this 16:35:26 TabAtkins: definition should be relative to the baseline, so that in a centred font the line would go through the centre 16:35:38 stearns, a fixed offset won't help here 16:35:50 SteveZ: this is a trigger that says that we'll break sequences of lines when the difference is bigger than a threshold 16:36:15 smfr: I haven't looked into this much 16:36:26 glazou: do folks want a week more to look into this 16:36:35 ACTION fantasai: write this up, with examples 16:36:35 Created ACTION-511 - Write this up, with examples [on Elika Etemad - due 2012-10-10]. 16:36:53 glazou: topic deferred to next week. 16:37:01 http://lists.w3.org/Archives/Public/www-style/2012Oct/0000.html 16:37:15 TOPIC: stacking contexts for position:fixed 16:37:54 sylvaing: should position:fixed elements create a stacking context? 16:38:07 ...: Microsoft are unconvinced about compat; reluctant to make a change 16:38:14 Zakim, mute me 16:38:14 glazou should now be muted 16:38:23 Zakim, unmute me 16:38:23 glazou should no longer be muted 16:38:25 TabAtkins: on mobile this happens, because fixpos is hard on mobile and this simplifies it 16:38:47 ...: easier to optimize scrolling on our mobile browser, if stacking context formed. 16:39:13 sylvaing: I'd like to see what makes you believe that. And are the sites in question designed for mobile web or for *webkit* mobile web? 16:39:40 ...: fixpos is a mess, so people relying on it doesn't tell us too much 16:39:51 TabAtkins: the scrolling people tell me this change would help 16:40:22 smfr: I implemented it on iOS and on desktop Safari. The proposed change makes implementation much easier 16:40:42 sylvain: so because it helps Webkit, we should adopt this change for CSS? 16:41:26 smfr: well, yes... we didn't find any big compat problem. Google also did some research and didn't find compat problem either 16:41:37 ..: I think it's a reasonable change 16:41:56 TabAtkins: It's bizarre to interleave into a fixpos element 16:42:17 TabAtkins: we think it's a reasonable change 16:42:35 ??: is this change in current versions of chrome? 16:42:43 s/??/krit 16:42:56 smfr: no desktop Chrome or Safari has released this yet. 16:43:04 TabAtkins: we've got Canary builds with this thing in 16:43:13 smfr: the sites that were broken are mostly Google properties 16:43:44 TabAtkins: and in those sites we didn't /need/ the behaviour which was breaking; it was accidental and we could work around the breakage 16:44:01 glazou: I haven't heard general agreement about this change 16:44:17 sylvaing: need more research 16:44:34 TabAtkins: I'll provide examples 16:44:52 -arron 16:45:02 Rossen(?): The overall intention doesn't seem crazy. But I would like to know what the damage would be across both mobile /and/ desktop 16:45:20 ...: please provide examples 16:45:21 +1 for this change, it makes implementation (and thus my job) much easier. But I don’t know about web compat. 16:45:25 ...: then we can make a group decision 16:45:38 TabAtkins: this change would also affect stickypos 16:46:09 antonp: Does the stacking context section of CSS2.1 explicitly distinguish between abspos and fixedpos? 16:46:19 antonp: fixedpos is considered abspos in most parts of CSS2.1 16:46:33 TabAtkins: issue is that abspos is auto, doesn't create a stacking context necessarily 16:46:35 -SimonSapin 16:46:41 TabAtkins: This issue is fixpos with z-index:auto - we want /that/ to form a stackign context 16:47:03 http://lists.w3.org/Archives/Public/www-style/2012Sep/0549.html 16:47:16 TOPIC: transform-origin-x/y 16:47:39 +SimonSapin 16:47:44 krit(?): Boris noted that apparently WebKit implements transform-origin-x and transform-origin-y properties. Should these be in the spec, perhaps? 16:47:58 TabAtkins: I think it's a reasonable set of properties 16:48:20 smfr: we should be consistent with properties which reference points and offsets, whcih don't have separate x/y properties 16:48:36 fantasai: in the case of backgrounds, where we have keywords it's hard to split it out 16:48:58 ...: transform-origin properties don't accept keywords so don't suffer from the awkward issues 16:48:59 x/y/z longhands is kind of natural for animations 16:49:14 TabAtkins: We don't want to do logical coordinates for transform-origin. Unlikely. 16:49:29 fantasai^: especially if we accept to add logical keywords, which i18n has been requesting for a long time and which we deferred to level 4 16:49:42 TabAtkins: so, webkit already does this 16:49:56 Bert: What is the use case? Yet more properties.. are they useful? 16:50:52 ?: Easier to animate when split up 16:51:07 fantasai: I can see wanting to animate axes separately for transforms 16:51:16 fantasai: Definitely would want that to be easier 16:51:30 fantasai: but for transform-origin, seems unlikely to be popular 16:52:26 sylvaing: Are there other places where we'd want to split this 16:52:37 smfr: perspective-origin 16:52:39 Sylvain: Could be fun to transform the origin 16:52:39 glazou: is there any objection from vendors? 16:52:39 sylvaing: do we do this only for origin? Why not other properties? 16:52:39 TabAtkins: it's definitely the only place in /transforms/ 16:52:39 smfr: no, there's perspective origin 16:52:52 http://www.webkit.org/blog-files/3d-transforms/perspective-by-example.html 16:53:25 TabAtkins: If you want to spin around the DOM structure: a) move the perspective origin (camera) or (b) move everything else. (a) is easy 16:54:01 glazou: the possibilities opened seem to be cool, but I need more than that to make a resolution 16:54:12 fantasai: i'd like to defer until dbaron has commented 16:54:12 lol 16:54:22 sorry, coughing 16:54:35 fantasai: re animations, seems more important to make transform itself easier to animate, rather than split up 16:54:48 transform-origin 16:54:48 glazou: OK, perhaps defer to F2F 16:55:07 glazou: 5 mins left.
