You can still use normal css if you're styling multiple things. I think tailwind shines mostly when the css does not need to be reusable or is encapsulated in a component which is how it works in some modern web frameworks.

The reason why it is big is efficiency. Once people know those class names by heart, they get a "nice" (arguably) default style very quickly without jumping between multiple files. This matters more than one might think..
