I'm trying to create an effect from the following link below for my navigation container and my container that will hold all my services. I don't know how to find such tutorials other than they look like grunge backgrounds.
Basically I will have a navigation container that will be 700px width and 60px height with a solid background color applied to it. Is there a way to add a background image to give the nav container a look like that? Same would apply for my services container (940px width and 600px height with a solid background color applied. I would need to somehow apply a background effect like the link below.
