footer is above the background image

I went to look at your screenshot but it was a 404…can you repost it?

The background is in the theme options….go to Appearance >> Customize >> Colour >> Footer Widgets Background setting.

I deleted all the color settings. Still image is cropped. Figure decided to move to the footer id = “st-footer-wrapper”
What else is in the way? Gray background can not find the source code of the page.

Perhaps I’m misunderstanding what you are wanting to do? Are you wanting that green graphic image to extend into the footer bottom area?

I’m from the previous image do what I want to say.

Need to fully green image shows all. Preview now cropped.

if you remove all the colors of the settings – remains a gray background, which I do not see where it is in the page source code. It discourages me))

This is more of a personal customization from what it appears and to do what you want with that image to overlap as a background for the content area, the footer, and the outside page background, this would take some major creative HTML work for you to do…it’s actually very complex. Long story short, unless you are very good at HTML, or hire a web designer, I don’t think you will be able to do this one because of how the theme’s structure is setup. You would also have to make sure the responsiveness of the theme is still functional as well (if you still want it to be responsive).
