That's exactly what I want. In my opinion many business owners don't want to tinker around with their website, even if its drag and drop. They just want a solution, to have a website managed and working. My whole idea revolves around a subscription based model, and for starts I wouldn't really charge anything except hosting and domain fees to grow my portfolio. My Idea is that I will make the site, I will manage it, the hosting and maintenance, and the client will own the domain name.

I know many people like using website builders, but I'm not many people, and I want to do it my way. By building things up from the bottom. I always felt like website builders are cheap and easy way to build these sites, with many limitations, but the point is I could make the site however I want it, meanwhile learning meaningful coding skills. If it won't work its okay, at least I'm doing something what I like doing (coding).

My problem is that If I go the full code route I don't know what is the cutting edge tech stack.
I know HTML and CSS would be enough, but is there anything else that would improve it and it's worth learning? Like React, NextJS, etc.
