There's also ruby-merge and ruby-align, but one thing at a time... (Via private feedback from Dae Kim) 119202 1 dakim 2015-04-02 20:22:58 +0000 I'm not sure this will be enough to support most use cases. Consider the snippet: 00:00:10.000 --> 00:00:15.000 <ruby>Line 1<rt>ruby1</rt></ruby> <ruby>Line 2<rt>ruby2</rt></ruby> Whitelisting ruby-position would allow control per cue, but how would I apply "over" to <rt>ruby1</rt> and "under" to <rt>ruby2</rt>? Wouldn't we need two unique <rt> spans or allow rubies to be class references or have attributes? 119211 2 philipj 2015-04-03 04:10:32 +0000 You would have to assign classes in that case: 00:00:10.000 --> 00:00:15.000 <ruby>Line 1<rt.over>ruby1</rt></ruby> <ruby>Line 2<rt.under>ruby2</rt></ruby> The style that with ::cue(rt.over) { ruby-position: over; } ::cue(rt.under) { ruby-position: under; } 119230 3 dakim 2015-04-03 23:20:38 +0000 In addition to whitelisting ruby-position, should the wording also change in the VTT spec? Change: A WebVTT cue span start tag "rt" that disallows an annotation. To: A WebVTT cue span start tag "rt". 119433 4 dakim 2015-04-10 22:55:38 +0000 (In reply to Dae Kim from comment #3) > In addition to whitelisting ruby-position, should the wording also change in > the VTT spec? > > Change: > A WebVTT cue span start tag "rt" that disallows an annotation. > > To: > A WebVTT cue span start tag "rt". Apologies. Change to the spec should be: A WebVTT cue span start tag "rt" that requires annotation; ... 119522 5 philipj 2015-04-15 09:06:41 +0000 Note that annotations are for <v> and <lang> and the annotation is the part after a space, like <v Roger Bingham> or <lang en>. I believe all tag allow classes without any modification, but we'll have to look closer when fixing this. 122528 6 silviapfeiffer1 2015-08-09 10:15:21 +0000 ruby-position is not supported by any browser other than Firefox. It's a bit early to adopt IMHO. 122550 7 dakim 2015-08-10 22:41:49 +0000 (In reply to Silvia Pfeiffer from comment #6) > ruby-position is not supported by any browser other than Firefox. It's a bit > early to adopt IMHO. I can't speak for them BUT ... the largest implementer of WebVTT uses it for more than native browser support. They also have a global presence. 123325 8 silviapfeiffer1 2015-09-26 22:13:31 +0000 I'd be happy to add ruby-position to the whitelisted CSS unless browsers object to it. 124219 9 zcorpan 2015-11-16 12:23:46 +0000 ruby-position is also supported in WebKit as -webkit-ruby-position: [ before | after | inter-character ] (Filed https://bugs.webkit.org/show_bug.cgi?id=151306 to unprefix.) 124221 10 zcorpan 2015-11-16 12:33:42 +0000 https://github.com/w3c/webvtt/pull/263 124222 11 zcorpan 2015-11-16 13:00:47 +0000 For ruby-merge, I suggest WONTFIX since the same effect can be achieved with markup, which is shown in the examples in the css-ruby spec. (VTT only has <ruby> and <rt> anyway.) For ruby-align, I filed https://github.com/w3c/webvtt/issues/265
