Search Styling – css help

Hello, first of all, thanks for the wonderful plug-in. I am requesting a bit of direction and help with the css styling of the search feature. To me, the search feature is one of the most important features of this directory plug-in. Is there a simple way to control the spacing and styling so it looks like the other gravity forms do?

Photo of how it looks now on my site:

I would post the url but it is a private directory. Just needing a bit of help to get me started. Thanks!
