XF 2.2 Need background image to appear on sides only

[CBI Web]

I figured out how to add a background image, but it shows up across the entire page.

I'd like it to only appear on the left and right sides, keeping the default color behind the content itself.

How do I do that?

What methods are you using to add the background image?

If I understood correctly you like the inner page to remain the same and set a background image for the body.

in order to do that first you have to give the inner page its own original (current) color

you do this by adding this code to your EXTRA.less template

.p-body-inner {
 
    background: #ececec;
}
