I searched for this over an hour and just don't find how to do this. Maybe the Customizr themes name is not the best choice for easy searching. :)
Anyway, as far as I read here I have to create a child theme and should be able to override any file in the theme I would like to by building up the same folder structure the original file has.
According to templates/parts/loop.php the following two template files should be used by the theme:
templates/parts/content/post-lists/post_list_alternate.php
templates/parts/content/post-lists/post_list_plain.php
So I copied these two files to my child theme keeping the folder structure, inserted a large-sized span to test but nothing changes when viewing the website.
Can anyone give me a hint what I'm missing? Most information I find in the theme documentation relates to classical style.
Thanks in advance Steffen
