I typically build webapps using .net/angular/node/whatever. But I want to try build a landing page website using WordPress and a page builder, e.g. elementor.

I assume a “theme” is similar in concept to a ui framework (e.g. bootstrap / material design), with some typography, css presets, js widgets, etc.

Therefore, if I’m using a page builder (and building a page from scratch):

• do I still need a theme?
• can I uninstall the default themes?
• is there a super light theme just for typography, given that I won’t use it for anything else?
