Recently asked Codex (GPT-5.2) to write a small single-page HTML frontend to debug some REST endpoints. As it was just a one-off tool, I put in no instructions about looks or styling at all. Lo and behold, the tool it wrote came with exactly that round-box style.
It seems to be the "default" style of some models for some reason.
Which makes me wonder if people already experimented with different style suggestions to get different results: "Make it look like an 1998 GeoCities page" / 2005 Facebook / Newgrounds / DeviantArt / HN / one of those Windows XP simulators with built-in window manager / etc
I vibe code web apps with Google's Gemini and I think it actually mimics Google's UI and UX because I see similarities between my vibe coded web apps and Google's web apps.
Every vibecoded site have this same dark look with shining hue-gradient borders, can't wait for the future the entire web be filled with this generic look
This is fair, although I ask for it to be dark themed to match what I think was the style of typing game I remember growing up with (it's been a while). Bumped up the font though.
Next time please ask it to respect system dark/light mode preference, it's trivial to do, especially for an LLM which can spin up light/dark alternatives easily.
By "free windows" do you just mean an unactivated copy of Windows? That doesn't prevent the user from configuring their preference in the browser itself.
My top complaint is that if I've successfully used a pattern, I want my text removed. I keep forgetting to backspace a bunch, then get frustrated that my pattern isn't working.
Automated accessibility testing needs to be in your loop, whether you are using an llm or not. Aria labels are easy to get right but they are also easy to forget.
