layout in opera

I’d guess that Opera isn’t picking up the ‘admin.css’ for some reason.
Tried a hard refresh ?

I’ve tried a hard refresh. No luck. Strange thing is that everything else has the right typography, in terms of fonts, colors and things.

It picks up the CSS file perfectly, but because of different float behaviors, Opera will display it differently. Don’t worry, nothing is broken, there are simply differences between how browsers will display different CSS rules.

Opera got a problem with floating fieldsets according to another post in these forums.

This IMHO is nothing to do with Opera specifically. It is to do with inconsistencies in the way a number of browsers implement floats. A uri would help so we can see the problem up close.

A minimal test would probably be something like https://www.cdr.se/fieldset.html which floats the fieldsets in FF0.9 but not in Opera 7.51.
