Tailwind classes are a syntax (especially since you can set arbitrary values e.g. `top-[-113px]`) and they still represent CSS. So really you're using a DSL with its own syntax, functions and directives on top of the CSS you should still understand. The main benefit is speed: you have a library of utility classes that are shorthand for common CSS patterns. If you are pretending that you're not writing CSS, you are forgetting how the browser is actually working -- eventually you may have to leave Tailwind and you'll find you've forgotten how to write good CSS.
