Custom CSS Editor to Make Website Imitating another

I would like my blog to look just like another that I've found. It's either squarespace or wordpress. Please let me know if you can help. NOTE: I do not have privileges to PM you since I'm a newbie. JR VIP only.

Maybe plug the url in this site and see if it actually is a WP site. If it is, it should make things a bit easier for you.
