I've been working as a Front-End Developer for 2.5 years and now I want to be able to design my side projects. I can do some little editings due to my psd-to-html experience but I want to go a few steps forward. I'm in need of resources right now, most of the tutorials I've found about Photoshop are about editing photos or some functions that I'll probably rarely use. And there are literally millions of "web design"-tagged tutorials also. Are there any paid/free courses about "web & mobile"-only design courses that you can recommend?
