Transparent sections overlay

Site URL: http://banjo-tuatara-524x.squarespace.com

Good day,

First post here, I am trying to set up a site for our product introduction. I have a product label jpg file which I want to act as a background to the home page and I want it to extend to the entire height of it.

Therefore, I am trying to achieve the effect of text sections plus the header and the footer being transparent.

I tried to enter several codes found in this helpful forum, but they do not yield the result I am looking for.

Sections remain with a solid colour.

I would appreciate your help.
