Change background header or entire header so it is different on each separate page or post

How to change background header or entire header so it is different on each separate page or post.
I use the full page template for the the gift store.

Does anyone know how to do this? I am putting a gift shop in the website and the main header background and header are not appropriate for the gift shop.... I use the full page template for the the gift store.

I prefer not to make major changes to code.

Check out what I am talking about at these links:

Thanks everyone,

add this to page css ( you will find it below excerpts box)

#header{background:#000 url('images/url/here/') no-repeat}

I pasted the code into page css and updated , but nothing on the page changed. Swift 6.1.8

#header{background:#000 url('images/url/here/') no-repeat}

see the test page at

Am i missing a step somewhere?

Where and how do I add the specific new background header after saving the code?

You should replace the bold text with your background image url
#header{background:#000 url('images/url/here/') no-repeat}
