I spent about a weeks worth of time to learn leptos. In order to understand the examples I basicly rewrote a lot of them to my style and created a page to show diffent SPA concepts in a simple page.
I took the resulting release build and dropped it on netlify. leptos-app
Eseentially you need to run trunk serve in the root directory. In order to build the css you can run a simple command. If you want the tailwind cli to watch the folder for changes you can add the -w flag at the end of the associated command and run trunk on a seperate terminal.
npx tailwindcss -i input.pcss -o output.css
trunk serve
