Ask HN: LLM struggles to center div too?

I used AI coding agents for the past half a year a lot with Flutter. Recently I had to work on the tailwind web project, and I was surprised how often it gets layout/UI wrong. Even with puppeteer attached, haveing access to raw HTML output and screenshots, it's still struggles to do simple alignment, centering things.

In a way, it mirrors famouse "centering div in css" challenge, but I wonder if it's the same experience for other people who work with web stack more often.
