Change menubar width

I tried to find the topic but I couldn't find the right answer.
I would like to change the width of the menubar and make it smaller.
Here is my site: soliloquycollective.com

Do I have to go into my Style.css and change this?
#index { width: 180px; background: #fff; /* line-height: 1.3em; */ }
#exhibit { margin: 0 0 0 215px; }

Thank you for your time.
