Yes using tailwind helps. In my experience you can use tools like vercel v0 to prototype design styles quickly and see which one you like. This step can be done manually if you have design experience and know what you want. Then you should write it down in a design document with specs like color scheme, font, overall style (minimalistic, futuristic, etc). This ensures that the LLM will keep this design style as context when creating components. It doesn't always work but it's better than relying on its internal context window.
