There are plenty of resources on Drupal theming, let me have a look at some good ones to share with you First you have to create a child theme :)

Thanks, I know there are great resources. For now I created some styling changes with the help of AI and a css override extension. The problem is that I am not that intrinsic motivated to do coding as real devs, and some small parts that I like to change seem too hard for a good prompt or ai output 😅
Theming can be quite complex, so it takes some effort to get started.

But you can alter / hook into your current theme by making a subtheme.
Thanks. For now I am looking for a dev that like to help with the small questions such adding some space between the rows, and outlining the elements well.
