Remove menu only, leave tag line and social links

I’ve seen how to remove the navbar box using the Customizr options in Appearance > Customize, and that’s done.

I’ve also seen the CSS to remove the menu (cf. https://www.ads-software.com/support/topic/remove-menu-bar?replies=19#post-4981971). However, that CSS also removes the social links and tag line. I want to keep those, deleting only the menu. I’ve tried not creating a menu, but that leaves “Add a menu.”

How do I remove only the menu, leaving the social icons and tag line?
