I'm starting to get into frontend development after sticking to backend for years. Does anyone know of a more fleshed-out set of rules of thumb for beginners in UI/UX development?
A collection of ui patterns https://every-layout.dev/
A great resource for css reference https://css-tricks.com/
https://typographyforlawyers.com/ Covers the basics with zero pretense
Kevin Powell on YouTube has great css rutorials https://youtu.be/rg7Fvvl3taU
Jen Simmons on YouTube and https://labs.jensimmons.com/
https://www.refactoringui.com/
Full of great tips and no fluff. Basically gives you a large but fantastic set of rules to live by, cohesive enough that you don't have to deviate from them unless you know what you're doing and have a solid need to. But otherwise it's a great foundation that you can implement in any design system.
