I've been developing for 2 years now and have been working at my first full-time job as a software developer for 5 months now (not counting my contract work) where I get to spend about 70/30 in backend/frontend respectively.
Whatever frontend work I've done has mostly been focused on placing new components on an Angular app with a sprinkle of CSS and mostly Bootstrap.
Not that my job requires this yet, but I'd like to strengthen my CSS skills so that I can feel confident in my ability to whip up anything I can visually imagine; instead of using a lot of basic CSS to make things look good enough (some position tweaking or color/formatting changes). I want to rely less on Bootstrap.
What resources have you personally used to improve your CSS skill when you were learning? I know there's plenty of tutorials out there (and I've access to a few), but for some reason, I can't seem to get the most out of these tutorials since you need to practice CSS enough to get a good knack of things.
Did you have a certain list of web pages, shapes, etc. that you wanted to replicate and just trial and error your way to the end result? Was there a structured path involved? Are there any practical/online resources available that you found particularly useful?
My motivation/Why: I do mostly backend, but I'd like to be able to whip up mocks for my personal endeavors/side projects more confidently.
