I have been writing a "clean" web development guide focusing on writing HTML and CSS that scales well: https://webdev.bryanhogan.com/

Maybe it's useful for people here. I don't use Tailwind or similar for styling, just CSS with modern frameworks like Astro or Svelte.

For every project I have the following CSS files:

- reset.css

- var.css

- global.css

- util.css

Other styling is scoped to that specific component or layout.

Using a JavaScript framework kind of defeats the whole purpose doesn’t it?
