> I was working on top of a huge CSS framework Well, that's the whole thing then, isn't it? The huge CSS framework probably had tons of hacks (as you say) to make things work in IE8... it's a bit disingenuous to say you wrote everything to be clean and without browser hacks, if the hacks all exist but are buried under a "huge CSS framework". Your whole experience could probably be restated as "I was working with a CSS framework that did a bunch of cross-browser hacks for me, and the tweaks I made to it didn't work in safari", which is a pretty uninteresting statement, because it's equally likely that any issues you had in safari are the fault of the CSS, and not the browser. (In fact, much much more likely.)
