I18N-ISSUE-358: [css-text] Arabic letters connecting between elements with display: inline [T] [css-text] http://www.w3.org/International/track/issues/358 Raised by: Richard Ishida On product: css-text Thread: http://lists.w3.org/Archives/Public/www-style/2014Feb/0302.html Raised by: fantasai About: http://www.w3.org/TR/css3-text/ So, probably this thread should be copied over to the bidi and ww-style lists. :) Adding them and topping off with a summary... and presuming that smontagu doesn't mind being quoted. ;) Reply here! The issue is (as the title says) whether Arabic letters connect between elements with 'display: inline', for example in this case: <p>foo<span color="blue">bar</span>baz</p> Browsers differ in their behavior. Simon Montagu suspects FF only connects if they are using the same font (face, style, and weight). Existing tests/discussion - Simple testcase: http://www.unics.uni-hannover.de/nhtcapri/temp/nastaliq.html Mediawiki bug: https://bugzilla.wikimedia.org/show_bug.cgi?id=60916 Mozilla bug (resolved WORKSFORME): https://bugzilla.mozilla.org/show_bug.cgi?id=236135 Webkit bug: https://bugs.webkit.org/show_bug.cgi?id=6148 Chromium bug: https://code.google.com/p/chromium/issues/detail?id=6122 Smontagu notes: > I think it would be very reasonable to expect cursive scripts not to connect > and shape across boundaries of "block" elements with display: inline, just > as we make such elements do bidi reordering in isolation from one another > (https://www.w3.org/Bugs/Public/show_bug.cgi?id=10815). Aharon suggested that we overload 'unicode-bidi: isolate' for this. Smontagu pointed out it's not a bidi issue and also affects non-RTL scripts. My take: Affecting non-RTL scripts isn't an issue; you can use bidi isolation on any element even if you are not changing its direction. And while it makes sense, it is overloading a bidi property for non-bidi reasons. I wouldn't object to it, given the correspondance of desired behavior is probably 1:1, but I see the point about joining behavior being "off-topic" for bidi. A reasonable switch might be whether there is positive padding/border/margin between inlines. It seems unlikely that joining behavior is desired across a non-zero margin, or that block elements would be inlined together without either whitespace or margin/border/padding as a separator. I don't think change of font or color should cause a joining break, however. ~fantasai
