'Responsive' child theme issue

How do I create a child theme that will inherit 100% of my original theme?

With only a style CSS in your child theme, it inherits everything in your parent theme.
BTW, did you modify the original files of your parent theme?
What are the files/templates in your child theme?

Thanks for your response.

I have only a style CSS in the child-responsive directory
containing the following code:

If I activate the parent theme it appears as expected.
If I activate the child a number of details change, menu, logo, etc.

Looks like a bug in Responsive, although I haven’t investigated fully. It reminds me of a problem I had with Nest and a child theme.

Responsive uses get_template_directory() to find its own directory (see functions.php), but when a child theme is in use this function returns the child theme’s directory instead. The result is that Responsive cannot find some of its own files.

A solution might be to copy the core directory from Responsive into your child theme, but if Responsive is ever updated without fixing the problem, you’ll have to remember to copy the updated core directory. I haven’t tried this myself.
