+1. I know this sounds dumb, but where do yo go to edit the css in a wordpress theme? Do you have to fire up the ole Dreamweaver and connect to server? Theme I have now has a section for custom css, guess that may be a start.
You should just be able to go Appearance -> Editor within your Wordpress Dashboard.
From there, you can look on the right-hand side (usually down the bottom). Here there is usually a style.css file that you can edit within the Wordpress interface.
