Design have two aspects, the doing (drawing, documenting, adjusting) and the thinking (what’s the actual problem and the concept to solve it, which will give me a frame of choices). There is a lot of content on solving the right problem - check the resources from IDEO, or for a broader view Don Norman for example https://www.amazon.com/Design-Everyday-Things-Revised-Expand...
Also don’t forget typography basics since most websites, apps and documents are mostly only text, there are lots of tutorials out there.
