I'm a backend developer, trying to learn enough design that I can start to design my own projects. I'm following along on a course called Design for Developers: https://frontendmasters.com/courses/design-for-developers/
In it, she uses a lot of Photoshop. Now, I'm fine w/ learning CSS, and learning the basics of design (color theory, layouts, etc), buut I don't want to have to learn Photoshop or Gimp or another such tool. It seems like it'd take me a loong time to learn them.
Do most designers recommend learning them? Or is it possible to use another / easier graphics tool for mocking out things, then converting them to CSS?
