I'd like balancing to be a CSS feature available for arbitrary content, but then the algorithm in the spec seems too expensive. 75984 1 glenn 2012-10-11 14:49:13 +0000 FYI, my suggestion was to perform ordinary wrapping, then to keep reducing the width and re-wrapping the content until doing so would cause it to increase in height. This is more expensive than normal wrapping, since it's performing normal wrapping repeatedly, but it's just an increase in the constant factor, not to the algorithmic complexity, and binary searching the width could reduce it to just a few passes. An example in JS: https://zewt.org/~glenn/balanced-wrapping.html 78583 2 ian 2012-11-21 19:08:31 +0000 I'm confused. What's the problem with the spec here? 78586 3 glenn 2012-11-21 19:20:01 +0000 http://krijnhoetmer.nl/irc-logs/whatwg/20120418#l-30 78633 4 ian 2012-11-22 07:11:06 +0000 This isn't CSS, so... what's the problem here? 78635 5 zcorpan 2012-11-22 07:16:56 +0000 That it's not CSS is a problem. > I'd like balancing > to be a CSS feature available for arbitrary content 78659 6 ian 2012-11-22 19:16:11 +0000 If you want CSS to define a balancing feature, that's great, but then this is in quite the wrong component. Even if we did have such a feature, we would still want to define it more strictly for WebVTT than CSS, since that would improve interop, IMHO. So this seems orthogonal. 78662 7 glenn 2012-11-22 19:34:17 +0000 How does it improve interop, when the results are going to depend on the UA's particular font rendering anyway? This is just another word-wrapping mode, and if it's useful in general and not just for WebVTT, it doesn't make sense for WebVTT and CSS to have *different* balanced wrapping algorithms. 119305 8 zcorpan 2015-04-07 13:24:46 +0000 http://dev.w3.org/csswg/css-text-4/#valdef-text-wrap-balance 119341 9 philipj 2015-04-08 07:51:37 +0000 Thanks, bug 28432 is to use this in WebVTT.
