I feel this may seem like a very strange question to ask given the circumstances, and hopefully this isn't breaking any rules. A few days ago I had a falling out with someone who happened to be hosting my website on their rented server. It's a very basic portfolio website with HTML and some JS for dynamically generating HTML elements from a Json file.

I'm pretty decent in HTML and JS but by no means a web developer, it's simply not my career. This means I can make a decent website but figuring out how to host it is beyond me. Are there any services that simplify this sort of thing, or is the process of renting and setting up my own basic server for a website straightforward? Github Pages maybe? Forms etc are not required.

I also own my domain, but it's currently still set up to link to that server. Once I get my own sorted out, will I have to worry about the two conflicting?
