It really is wild to have seen this happen over the last year. The days of traditional "design-to-code" FE work are completely over. I haven't written a line of HTML/CSS in months. If you are still doing this stuff by hand, you need to adapt fast. In conjunction with an agentic coding IDE and a few MCP tools, weeks worth of UI work are now done in hours to a higher level of quality and consistency with practically zero effort.
However, I feel that there is a big difference between the models. In my tests, using Cursor, Clause 3.7 Sonnet has a much more refined "aesthetic sense" than other models. Many times I ask "make it more beautiful" and it manages to improve, where other models just can't understand it.
