New to DW, need CSS Help/Advice

[liri_stargazer]

Hello, all!

I am new to DW and am trying to tweak the coding on my page. I did quite a bit of tweaking to my journal on LJ and I understood how to do that because I understand standard HTML and how to structure the commands/code.

However, DW is CSS and I know absolutely nothing about CSS or layers. I am not afraid to get into the basic code and change things to see what happens as I do it. I oddly love coding so I like to learn and build on my knowledge as I go.

At this point I want to do a simple tweak of the Title and Subtitle. I want to change font and probably color.
Currently I am using Abstractia.

My questions are:
1. Is there a basic tutorial or how-to that will walk me through where to find the code I need to modify?
2. Does anyone know of any basic online CSS tutorials that will help me learn what I need to do?

Thanks in advance for any help,
Liri
