2. jpg-png and different sizes and screen resolutions. How is it decided?
3. So I realized that with the advent of css3 it is now possible to do some graphic things that were previously only possible in graphic packages (like rounding for photos).

Answer 1

1. Yes, there is nothing difficult there. Learn a lot about Photoshop.
2. SVG graphics solve the problem or use css. Google "responsive image css"
3. Yes, that's right. You can do a lot more with css3 than you can imagine. Without any JS, they make full animations and other incredible things on css3 alone.
