Hey @JFAN5 ,
sure! Child themes are very cool. They work in a way to give you more control over your theme in the areas you actually need it.
Yes, it looks almost empty. But all the files from the original are linked to your child and are available as for example, templates when creating a new webpage. So if the original theme is a file at this path:
@marketplace/@some-developer/theme/templates/example.html
That file is also available in the child, even though it isn’t visible.
But let’s say you want to change example.html. Put your own spin on it. You can recreate that file from the original under the same path within your child-theme. Now the new one with your changes becomes the one accessible for website pages.
The reason for this are updates from the developer. If the developer of your theme introduces changes to example.html these changes are feed into your child. But if you’re using your own version, updates aren’t possible, of course.
You read more about child themes here. Things will become a lot clearer then.
Cheers,
Chriso
