Missing several classes

[Jarrodsz]

Implemented like readme.md

But the problem is im missing all kind of classes like border-red-500 does not exists in the build tailwind.css

How to resolve this?

I even tried creating a new rails 7 application with the prefix for tailwind css and it gives the same result. No border-red classes only border-grey exists :S

<div class ="border-2 border-red-500">
  xxx
  x
  x
  x
  x
</div>
