If there is one good thing to say about ChatGPT is that I think it's great for generating website templates (or entire websites) because it doesn't add unnecessary bloat like non-standard fonts from Google or CSS/JS frameworks, and the resulting code is easy to navigate without code comments. You will know exactly where to put your content, or you can tell ChatGPT to put the content in there in the second prompt.

I recommend using that over using a WYSIWYG editor or downloading some HTML5 template that includes a bunch of external scripts from Google, Meta, and Cloudflare, and being bound by some restrictive license.

Just remember to be very specific on what kind of website you want. Just typing "dark-themed HTML5 template" will generate the same template that everyone else has. You need to specify what you want in the prompt such as a side bar for social media links on the left with updates on the right. It's also a good idea to specify what it's for such as a blog, a company, or a portfolio.
