[jasss]

hello, i would like to add a background image in the Dawn theme.
here is an example of what i mean:  the image in the background around the page
https://www.universeonatshirt.com/i-like-it-here-by-universe-on-a-t-shirt-shop

but i want to create that in the dawn theme here:
https://almost-summer.com/

i dont care if it's not in the full width image photo banner

Hi there,

I can't seem to get this to work either on Dawn 2.0.

Can you assist? Please let me know where approx this needs to go in the Base.CSS coding and if there have been any alterations?
