From: Andreas Prilop on 23 Apr 2010 10:39 Testcase: http://www.user.uni-hannover.de/nhtcapri/temp-5.html Opera 10.51 (Windows XP) takes "padding-right" to mean "padding-left" on table cells when the text direction is right-to-left; other browsers (Firefox, Internet Explorer, Konqueror) don't. Can you reproduce this behaviour in Opera? Bug or feature? -- In memoriam Alan J. Flavell http://www.alanflavell.org.uk/charset/

Yes, Opera 10.10 on GNU/Linux does it too. > Bug or feature? Bug. The spec says padding-right means padding-right (and it would be really confusing if right started meaning left when direction changed). What all browsers do is swap left and right for whichever of margin or padding they use in the default stylesheet to indent list items when direction is rtl. One way to do this, I think what Firefox did, is create some custom properties like -moz-padding-start and -moz-padding-end and use those in the default stylesheet. Another would be to invent a new pseudo called :rtl or something. CSS3 probably has padding-start/padding-end (or something like that, don't know what name they used) as well as padding-left/padding-right.

Bug or feature? Opera is a lone ranger when it comes to fonts and font sizes. "padding-right" means more what it says, for example, in Opera when you use pixels. -- dorayme

Confirmed for Opera/9.80 (Windows NT 5.1; U; en) Presto/2.5.22 Version/10.51 (on Wine, where it is a PITA as compared to Opera 10.10). > Bug or feature? Maybe neither. CSS 2.1 contains a note about the HTML `dir' attribute with regard to table columns. AIUI, it is not a good idea to use that attribute on a table cell, instead of the `direction' CSS property, and other CSS on the same element to begin with. <http://www.w3.org/TR/CSS21/visuren.html#propdef-direction> Isn't there a bug tracking system at opera.com?

The usual CSS Caveats are particularly important here, because writing direction is not a casual rendering feature like color, font, or padding. Instead, it is an inherent feature of the writing system. It would be absurd if your English-language page got right to left direction (with directionally neutral pieces running right to left, default alignment set to right, column order in tables right to left) just because your style sheet is not found, or is not applied. ?It would look odd, wouldn't it (Latin letters would still run right to left, since they have inherent left to right directionality, but e.g. some punctuation would get thrown in odd places.) Well, _that_ won't happen of course, since default direction is left to right, but the situation is just as absurd in the real case of writing systems that differ from this default. I don't see much reason to use the direction property (instead of the dir attribute in HTML) except in cases where you deliberately play with direction - on fun pages, basically. -- Yucca, http://www.cs.tut.fi/~jkorpela/ |
