I develop website using chrome and mac os as development environment.
Since my audience is pretty specific I don't feel the necessity for too much backward compatibility with IE8 and less.
However to my great dismay, even IE9 looks totally broken...
I would like to know if there's on the web a tool that could tell me what probably went wrong with IE, that is a webapp that parse the rendered css and check which rules are probably totally broken in IE9.
