Thanks for the reply. I have taken your advice and tried it out for the first time. I normally edit css files directly through FileZilla. Your solution presents the same problem for me however. I am still not sure which exact file(s) I need to edit or exactly what part of the file(s) I need to edit to get the changes I listed above.
I was hoping someone could direct me to a tutorial or maybe even quickly explain how to do it here. It would be so highly appreciated!
