@upsuper's issue https://lists.w3.org/Archives/Public/www-style/2015Feb/0096.html > It is not clear how text decorations should be rendered on ruby elements, or more specifically, what should happen on sides of short base text with long annotation? > > For example, if we have content like: >``` > <ruby>base 1<rt>a very very very long annotation</rt>base 2<rt>another very > very very long annotation</rt></ruby> > ``` > > then we specify "text-decoration: underline" to `<ruby>` or some of its inline ancestors. What should happen? Currently, WebKit and Blink and Trident won't draw the underline in the gap between the bases, and between text preceding/following and the ruby, while Gecko will draw lines in those places. More precisely, Gecko currently extends the decoration lines to the boundary of each box, other impls don't do that. > > It seems to me that our (Gecko) impl makes more sense if the ruby is part of a sentence, while other impls make more sense when ruby is put alone as a single word. > > This problem becomes more complicated when considering the different values of ruby-align. I guess users of "center" and "start" probably don't want to extend the lines to the boundary of boxes. @patrickdark's response https://lists.w3.org/Archives/Public/www-style/2016Dec/0106.html > I think underline text decorations should always extend over annotations for `ruby-align: center`. I ran into this issue in Firefox 50 recently where a link was split into two to three components because of the "ruby overhang skip" effect and ultimately decided to hide all annotations nested within annotations because the presentation was so ugly. > > I can imagine desirability for ruby underlines not extending over a final overhang for `ruby-align: start` or empty bases at either end of a ruby sequence, but I don't think it would be terrible for underlines to extend over those annotations either. > > I've posted some (real world) ruby examples of the text I was working with at > https://patrick.dark.name/sandbox/miscellaneous/ruby.text.decoration.break.xhtml -- GitHub Notification of comment by fantasai Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/5996#issuecomment-800743869 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
