Summary: According to some people from Japanese ebook companies, text-combine-upright (a.k.a horizontal-in-vertical, or tate-chu-yoko) is a must for Japanese vertical layout. Without the proper support of this feature, a book may not be considered complete, and thus cannot be sold online. This is also a common pattern for layout of Traditional Chinese.
There are two values for text-combine-upright, one is "all", the other is "digits <number>". We are currently going to implement only "all", because that's much easier to implement and can solve the majority of the problem people have. Bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1097499 Link to standard: https://drafts.csswg.org/css-writing-modes-3/#text-combine-upright Platform coverage: all Estimated or target release: Firefox 48 (or 49 if missed the cycle of 48) Preference behind which this will be implemented: layout.css.text-combine-upright.enabled DevTools bug: This doesn't seem to need any additional support from DevTools. Do other browser engines implement this? All other browser engines have had the support of the functionality of "text-combine-upright: all". Edge and Blink have already been shipping it unprefixed. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
