So that sadly did not solve anything,

I added the CSS an enabled the header on all pages but even if I set the css to 111px there’s no change.
to make it better understandable I made screenshots of how it looks with the header and what I mean.
the 1st is the landing page with enabeled header, just the huge header picture on it, then you have to start scrolling to get to the page (ab2.jpg), and opn any other pages the header is cropped like in the 3rd picture.
I would like to have the header size like in the 3rd picture just with the whole image

Hi
My url is annabella.rocks

I will try to explain
At the moment I have a picture right below the header section. If now in customizing theme I add it to all pages it gets blown up to like 1/3rd of the page in the landing page and you have to scroll all the way down no matter how small I upload it
Then on the following pages it gets like cropped so only the middle shows.
So my question is it possible to have the picture in the size it’s currently on top of every page in the header.
