Really really need help here. Line codes do not match with CSS.

Okay, I would really appreciate some help and I have explored many articles in an attempt to remedy this issue. When I use firebug for a specific area of code I want to change it displays line coding. Specifically, I am trying to change the color and font style of the title and tagline. The website is http://www.autofindvb.com

Please read on:
It says line 61, which is supported by opening the source code. Moreover, when using firebug I am able to edit it to look like what I need.

This is how I am attempting to edit my code. I copy/paste twenty eleven style sheet into dreamweaver and have tried notepas++. I locate code line 61 and it does not match.

Am I editing wrong? Is my saved style sheet wrong? Why is it showing properly in firebug, when pressing ctl U to open source, but not when I need to maker permanent changes?

I have been at this for 3 days now with no progress. I really need help with this. I am totally new, so please dumb it down for me slightly so I am able to mentally map what you are conveying or so I can physically navigate your instructions.

My ineptitude is through the roof right now!
