Except Opera did tabs on top first. Please people every god damn time you say someone is copying Chrome, the idea originally came from Opera. Stop talking about things you know nothing about.Chrome really struck a chord with their tabs-on-top approach, with both Firefox and IE mimicking it to a degree.
It's also about time IE got their shit together as a browser, both on the rendering and GUI fronts.
They had such a huge market share lead they didn't need to improve.Ive never gotten the point why they dont really treat it as a part of a system and make sure it is absolutely right. I mean, it does come with every single windows computer/laptop.
IE8 introduced standards mode. You should not really have to write separate CSS rules for IE today, unless your site must absolutely have IE6 compatibility. Otherwise I leave things broken in IE6first they need to make it standards compliant, i should not have to special mark my css/html code for IE, at least all the other browsers are mostly standard compliant.
