If you're a (junior) front-end developer, then use the website to show off your skills. In other words make it responsive, accessible, use js libraries _when it makes sense to do so_, maybe some visual bling (background effects, scroll snap, a nice design). Https obviously, clean css, small page size, must load quickly.
The reason I'm recommending this: I recently looked for a junior web developer, in the zero-to-little experience range (combined work & school curriculum). I received more than 50 CVs, all stating that they were fluent in HTML/CSS/js.
Less than 10 of these had personal web page links. I looked at all of these web pages, and they were a big factor in who got an interview. Off the top of my head, I don't think we interviewed a single person who didn't have a personal resume/portfolio webpage, because we already had a pool of candidates who demonstrated that they had an actual practical experience of building a web site.
