> I think that separation of concerns (i.e., the whole idea that the markup should be completely independent from the styling) is something that has been burned into our brains because of the history of CSS (trying to get people away from using tables, sites like CSS Zen Garden, etc.) CSS has come a long way since CSS Zen Garden. With CSS grid and flex, you can create components with less markup and small amounts of CSS. The example on the tailwind site https://tailwindcss.com/docs/what-is-tailwind/ https://tailwindcss.com/docs/what-is-tailwind/ just looks like a steep learning curve to me. I could write that same component with much less HTML and just a few lines of responsive css.
