Need Inline CSS help

I've run into a theme conflict on my first GF project.

Labels and fields need to be on the same line.

Nothing I do inside the dashboard makes any difference, so I'm assuming additions will need to be added to my child style sheet. I've searched the forum, but so far I have only been successful at putting the 3-part date form in a single line (yay!), but can't unattach the Zip field or put the labels inline.

The form is on a test site here:

Thanks for any help.

Thanks David. "Output CSS" is set to "yes". I'm generally pretty good at scoping these things out but I couldn't find your CSS stylesheet either.

The site is being developed on WP multi-site. Could that somehow be a factor?

Rob, that worked. Now the form looks like the preview from within WP. I was able to delete all additional CSS instructions from my stylesheet. Wonderful! Thank you very much.
