I am trying to add a background layer that will go behind all of my content on all of my pages in my WordPress site. I want it to be one of those semi-transparent backgrounds and I have an example.
On this site they have that transparent grey background behind all their content that still allows the main "river" background to show. I want to attain that same type of semi background onto this site
so that once I get my sliders and all that on the pages, there is a contrast between the white background.
I am a beginner to web design and wordpress so anything will help. Remember I would like to apply it to all of the pages and posts on the site. Thank you so much.
My name is Chris.
