Thank you for creating an awesome theme! I really like it a lot.
I tried to create a child theme. Basically, I created a folder, created the standard chile theme css file with the import, and that was all I did.
The result was that I lost your default graphics in many places, and the drop-down menu stopped (for the narrow screen) went black.
Can you please tell me the right way to create a child theme for Alexandria? I'm guessing that there are additional files to be copied over, but that is just a guess.
