It’s the frames type of design, left an outline, right content.

Yeah, that's probably it. Late 90s, early 2000s, we all used these magical frames.

It's also the stars as background image. You don't see this stuff nowadays, it would be too low-pixel non-fancy. White little pixels on black background where so sci-fi in the 1990s.

Web design these days values "bland" and/or "look the same as everyone else" above all else, it seems, even to the point of reducing usability.
