Maybe unrelated but can someone help me point to a good place to start learning CSS by really understanding it at fundamental level. I have had start and stop bouts of learning CSS several times before and I couldn’t understand it logically like other languages or frameworks for reasons I can’t clearly explain. I avoid frontend programming mainly because I don’t know CSS.
