How would I program this?

This is my blog, http://blackjackbettingstrategies.blogspot.com/

What I want to do is put a nice border around each one of my blog posts and make them have a light green background. I am then going to change the outside to dark green. How can I do this?

 

open css file.

find .post class and add

border: 1px solid #000; bacground: #123

Code (markup):

then find body and change color value of background.

good luck!

 

thanks chief!
