on Opera 11 and 12, old firefox (4 i think) my webpage which has in css set-up "font-size" to 1em and 1.4em, worked but on new Iron/Chrome, Firefox and Opera 15/16/17(chrome) the size in em is simply totally different rendered (site always zoomed in 100% - normal) check the screencaps, left is older, right is newer browsers: http://i39.tinypic.com/14o0uhk.png so what the hell is happening ? this isn't something ancient... it is css 2 so just in case I switched to % so I tried with 105%, then 112% and guess what... yet again huge difference in font size render seems like only Opera 11 and 12 render it correctly, while all other browsers are stubborn forcing their own crap so again what the hell is happening ?
