Site Title, Tagline

I am using the free version of Catch Inspire for www.morrowtherapy.com. I would like to get rid of the search bar and center the site title and tagline. I looked thru the forums and found some CSS to add, but nothing seems to have changed after clicking "Publish". These are centered on the preview, so I was bummed when it was not actually centered on my site. Also, how to I change the font size for the page name titles? I would like them to be a bit smaller than the site title.
