It seems like this isn't a Tailwind alternative, that's something the poster made up. I think it would be best for a mod to change the title here.

However, there's a point in using something like BEM (https://getbem.com/) for your class naming scheme, and go away with the utility classes within your HTML. The utility classes from Tailwind (and Bootstrap) provide great consistency, and this seems to provide the same but from within your SCSS itself.
