How do i create a theme from scratch without knowing coding?

Hi, I’ve recently just started building a basic multi-vendor market using Elementor + WCFM.

I want a very specific look for it (as close to [this](takealot.com) as possible).
which I unfortunately cannot find through any of themes provided by elementor.
I did purchase elementor pro so I believe there’s nothing holding me back from achieving my goal except for the lack of knowledge on how to go about it.
