If you're new, start with "Tailwind CSS: From Zero to Production" (Video playlist, ~1 hour total, split in chunks): https://www.youtube.com/watch?v=elgqxmdVms8&list=PL5f_mz_zU5...

Alternatively, read this (it's a chapter from a book which is meant to help engineers "get" design): https://www.refactoringui.com/previews/building-your-color-p...

The book chapter outlines the philosophy, and Tailwind provides a functional system for putting it in practice.

For both of these, you don't need any CSS background. Not only does the video series teach you Tailwind, it'll also give a foothold onto CSS, and how to use it in practice to make reasonable websites even if one is design-challenged.
