Thanks for the quick responses!
Have you checked the IE-only CSS files? They could be overriding some of your modifications.
I hadn't before, but have looked into that now; that proves to be quite tricky though... (Simply increasing CSS specificity didn't help, unfortunately.)
for the 90% : in main.css change this :
/* scale back up to a sane default */ #globalWrapper { font-size: 127%; width: 90%; margin: 0 auto; padding: 0; }
That's what I'd done before (except for the padding and font-size).
for the tabs : in monobook.php [...]
I was afraid that I might have to hack the skin... But this looks interesting; I'll give it a try!
there might be a cleaner way to do this (without changing php code)
None that I can think of, unfortunately...
using those dedicated css, you can correct all IE bugs
Good to know - I'll do that. Too bad there's no [[MediaWiki:Monobook_IE60Fixes.css]]...
Thanks again, to both of you!
