Font-size issues comparing chrome and Firefox

Question

I built a site and the problem is, chrome display font-size 1px bigger than Firefox. I tried several ways to match the font-size, specified it in px, in % set t

Answer 1

em is scalable and px is not. Set the font to a defined px size and you should be ok. em can be desirable in certain circumstances, but if you are worried about 1px then you should set strict pixel sizes.

EDIT: Just reread and I see you have tried setting the height as pixels already. Don't have a clue then as I don't have Chrome installed here to test. :(
