Solved Background in search result (dividers)

I would like to put the background in the search result as well as in the list of articles (divider). I guess you can do something with CSS.
Attach:
img_1 = list of items
img_2 = search result

Thank you

 

I want to put the same background that is in:
https://apartamentosturisticosasturias.com/articulos/

On the search result page:
https://apartamentosturisticosasturias.com/?s=

All the best

 

Okay great.
I added a z-index to the pagination that was not working and that's it Ok.
I also changed 80% to 100% that affected single.php and more or less everything was as close to what I wanted.

Thank you so much
