ff2 mac: doesn't understand floating-point percentages (ie: 107.3% = 107%) - ran into this with font sizes.
ff3 thinks that if your parent is visibility:hidden, but you are visibility:visible, that you should display. (wrong.)
IE8 VHD from microsoft on vpc2007 is not the same as ie8 in the wild. Button element widths seem to be at least 1px wider in the wild.
I've decided to use a very tiny bit of javascript to free me of css hacks. I already use js to add a class "jsEnabled" to the <html> element so that I can style things differently if I know that javascript is going to swoop in and alter them later (tabs, carousels, etc). Taking this a step further, I put the browser name + version number in the html element classname. Then in the css, you can write ".ie7 .my-div {float:none;}" Sure, we're not supposed to rely on javascript. But we usually do. And this is just for minor tweaks anyway. The site will still *work* with js turned off, you'd just lose that tiny css tweak you made that relies on it.
