Hello,
I’ve added the feature image to my post, but now the element on the post page includes the feature image which I do not want.
I want to keep the element background the same on al posts, pages, etc
The featured image should only displayed as the background if you have a page hero assigned to it with Featured image as the background image option.
If you don’t want to use the featured image as the background, then you need to create a page hero with either custom image or solid color as the background and assign it to posts.
