Out of the 3 main web languages I use to develop my games (HTML, CSS, and JavaScript), CSS is definitely my least favorite.

HTML is relatively simple and understandable such that bugs rarely get introduced into my HTML code.

JavaScript, while janky and not known for good performance, will work without too much trouble compared to other languages (I'm looking at you, C++). No segfaults, effortless type casting, intuitive syntax, and debugging is fairly easy. Worst part is editing HTML and styles with JavaScript, it just feels clunky, to both the programmer and the CPU.

And then there's CSS. Despite being a language dedicated to making things look pretty, it's just an unintuitive list of properties on HTML classes. So many times it takes way too long to do a simple thing like center text in a div when there is other text that is meant to not be centered. But I guess I'm not using it to its fullest potential, as I recently came across an article that listed many pretty graphics, often animated, that was purely made using CSS.
