Easier said than done, and completely ignoring the intricacies of "just have a website".

I can write the html, CSS, JavaScript needed for a website, I can spin up a local web server to serve these files, but setting up an internet facing website, no. No clue how to go about it, how to secure it, and how to maintain it.

Give me a step by step guide that is simple, and can ensure security and privacy, and I'll have a website. But until then I'll use what's convenient.
