Customizing FORMFIELDS / DROPDOWNS using CSS

Hi guys, I’m just starting to learn advance css coding and was playing around on how to customize a formfield. I was successful with the SEARCH BAR but is having problems with the DROPDOWN OPTION. I attached a screenshot on how the file looked like on IE vs FIREFOX, and another file that I wish to achieve the looks from.

I can not seem to find any tutorial here (Kirupa’s) and even is unlucky with google lately. Can someone please point me somewhere?

thank you
