Custom CSS when Switching Theme

Hi,

I was using Jupiter theme previously and I edited the CSS via WP > Jupiter > Theme Options > Advanced > Custom CSS.

Now I’ve switched to Listimia and I can’t find something similar, as in Listima is not in the main WP admin control panel. I understand that the custom css can only be found under Appearance.

my question is, since Listimia is not in the main WP control panel, does my custom css from editing the Jupiter Theme options disappear?

Thank you.
