1. When you're working with this code, it's far easier to read with proper formatting and syntax highlighting. I know people take issue with the verbosity of tailwind, but anything will look awful if you remove formatting.
2. This is lacking an equivalent non-tailwind approach. If you can share the equivalent vanilla HTML/CSS (or pick your preferred framework), and then paste it here as an unformatted text blob, this might be a bit more fair.
3. I don't think it's fair to describe this as just a "box with rounded corners and a top and bottom section". That can be done with tailwind with less complexity/syntax, if that's truly all you want.
