Opus 5.5 is an order of magnitude better at design and design nuances than GPT 6.1 Sol, surprisingly.

If there is a design that LLMs do that you don't like, tell it that. You're allowed to be picky.

Using a coding agent really gives you that with minimal guidance. Try in opus session: "I want to build a website which looks similar to https://hackerbooks.org, but instead of showing books extract the top rated topics, render each toipic as a post it card" should give you a usable and maybe even good layout.

This is the stock claude UI

honestly claude did the frontend, my instruction was "make it feel like hackertube, but for books". radiospiel's advice is right, just try it. only needed nudges for performance, but otherwise its claude magic :)
