Hi Alan, > Mmm, ok, these are the same results that I see when IE9 preview is in > IE7 document mode or when IE8 is in IE7 compatibility mode. > > For IE7, /9, /a, /b, /c and /d works. > For IE8, /0, /9, /a, /b, /c and /d works. > For IE9 preview, /0 works.
Interesting... It looks like if you replace "background" with "color" then \9 works. Hence why I suggested to use :root #ie9 {color: teal\9;} but then :root #ie9 {background: teal\9;} would fail. So it's more reliable/safe to go with this instead: :root #ie9 {background: teal\0;} -- Regards, Thierry www.tjkdesign.com | www.ez-css.org | @thierrykoblentz ______________________________________________________________________ css-discuss [cs...@lists.css-discuss.org] http://www.css-discuss.org/mailman/listinfo/css-d List wiki/FAQ -- http://css-discuss.incutio.com/ List policies -- http://css-discuss.org/policies.html Supported by evolt.org -- http://www.evolt.org/help_support_evolt/
