You need to start by copying. Find a page and try to reproduce it on your own. Keep doing it and you'll get to the point where you're comfortable doing your own designs. I am currently maintaining three SaaS products I built with Go. It's a great tool for the job. One was with Go with vanilla HTML/CSS/JS (with Turbolinks classic for snappy page loads/transitions). The other two products were built with Go and HTMX+AlpineJS+Tailwind CSS. In retrospect, I'd like to remove Tailwind as it bloated the HTML a lot and rebuilds are slow (~300ms to ~500ms per-build). Alpine has its uses, but I don't think I used it enough to really need it.
