Having grown tired of of JS overengineering hell and more dependencies than lines of code, I'd like to go back to the basics for a bit and make a website using just HTML/CSS
What are some good resources to master modern HTML/CSS?
TraversyMedia on Youtube. Brad has AWESOME tutorial videos, both crash courses to learn and project tutorials to build sites from start to finish to learn the skills you need. He also puts out Udemy Courses, one of which is "HTML / CSS From Scratch" (title might be off a bit) and you can usually get it for $10 from a link on his YouTube vids.
