You suddenly reminded me about another good Tailwind thing: linter will highlight "p-1 p-0" as a mistake. I've never seen linters that warn on "your-custom-p1 your-custom-p0", but Tailwind makes it possible.

This is not a cascading issue. This is a "You're holding it wrong" issue. And when Phoenix does write 'p-0 p-1', Phoenix and Tailwind are not a good match.

If the alternative is:

.foo { padding: 0; padding: 1rem; }

then I can see the precedence but I don’t see how it’s an advantage. You can write bad code in any methodology.

That seems like an issue with Phoenix and not Tailwind or the Tailwind approach.
