CSS Battle is a fun way to solve some CSS puzzles. There are many ways to solve a CSS battle problem and certain ways that are better than mine. The point is having fun and not worrying about the characters or the properties used. You can also make use of Unicode solutions which are mostly used as the top solution in many CSS battles. Having said that, I won’t recommend learning CSS for professional work through these solutions as you will rarely encounter them in a professional setup. You can check MDN, CSS Tricks or my other page: mini projects to learn some CSS skills for frontend development.
