Chrome vs. Firefox margin/padding

I’m having issues with getting the sub-nav of this page displaying the same way in Firefox and Chrome. I’d like it to look exactly how it looks in Firefox. With everything lined up horizontally and nothing falling out of the one line (as it does in Chrome). There are four sub-navigation pages under “Studio” and that’s why they’re all black.

(The code is not compliant, but that’s because I was getting the sub-navigation to only show up when the parent was clicked, which took a lot of troubleshooting and I’ll leave it as for now.)

I’ve added the reset.css stylesheet and even added another wildcard to the regular stylesheet in case Chrome wasn’t picking up on the reset.

Thanks for any suggestions.
