".masthead" is an example of high-level abstraction class you might find in complex CSS. This is the kind of thing where there's no guarantee your markup will match how the classes were "intended" to be used. How the classes fit the markup is the hidden part. I didn't say Tailwind isn't an abstraction. It absolutely is, but it's a minimal one that is transparent. Every class does exactly what it says, nothing more, nothing less.
