Ok, thank you. It is possible to customise it somehow? Do you have any tips?

Thanks

Hello,
this is the code I had already added, as you can see in my first post. 🙂
The problem with it is that it shrinks it permanently. I want it to get smaller when i scroll down the page and back to normal size when I get back to the top of the page.
Just to give you an idea:https://www.w3schools.com/howto/howto_js_shrink_header_scroll.asp but applied to the image and, if possible, the menu font too.
Thank you
