I'm still hanging in understanding how themes in magento 2.0.7. So far it seems one practically has not to touch a single template file, only design files it seems. Though I'm struggling to find where to start when I want to have my own design. Just a starting point where to start adjusting. Seems to be hard.
For example. I base my theme on blank. Blank has not a single template file. I found that instead module-theme delivers the template files for blank. Now I wanted to follow the conventions and create my page with design files. But it is hard to do. Template hints does not really help since it seems to only show small template parts, not the surrounding templates and it does not show the design files at all.
I then found that default.xml seems to define somewhat of a base layout. So I copied the default.xml from module-theme. I found that seems to be defined in there and I can find it in sourcecode then. Though in sourcecode there are more surrounding divs:
It seems none of them is defined in default.xml, though I need to access those classes in order to put in my own classes to define my design.
So can someone tell me where to look at to finally find the real main design file where everything starts?
PS: I would like to write registered but it seems stackexchange has a problem with the email formats. It seems it does not understand that an email can contain a "-", which is a problem I came over on many sites. It leads to me not getting a single email from stackexchange. Unfortunately I can't even ask in meta, where the right place should be, because only registered users can post... ::)
