Almost 100% in lighthouse for both mobile and desktop, responsive, reusable components, dark/light mode and a design that was better than I could do in the 2-3 hours I spent doing it (while sipping wine).
I know its not a solution for everyone, and probably won't work for the prettier designs out there, but you can go a long way with these tools this day.
I know there is a reluctance to not use LLM's for code tasks, and I am one of the largest critics, but for me this solves a real pain point. I don't want to write CSS/HTML anymore and these tools do a good enough job of it that I don't have to.
