Usually, things work identically in FF <-> Chrome (there are a few minor yet irritating exceptions -- most having to do with drawing things dynamically with css), and even the latest version of IE renders 95% of what I throw at it correctly without a hitch.
Unfortunately, saying something doesn't work in opera is like saying you can't play ipad games on a cookie tin.
That said, Opera uses blink now, so things *should* render 1:1 in chrome and opera, but opera has it's own little added quirks.
