CSS auto horizontal margin with a bottom margin

Question

I have a div with a margin: 0 auto; and that part works great. I also want to give this div a bottom margin of 80px. I've tried margin: 0 auto 80px; and that work fine in webkit browsers, but not in FF. Anyone know how to achieve this for all browsers?

Answer 1

What you said (0 auto 80px) should work, regardless of browser unless too old. I've done it many times myself without error. I think something else is going on here, I know it sounds silly but maybe some other selector you're not aware of? this happens a lot more than one would guess.
