When learning Ruby last year I took a quick course over at TryRuby … it’s basically an interactive terminal that executes ruby commands and holds your hand through the language.
Likewise, over at Codecademy, they will have you perform increasingly more advanced JavaScript inside of a console so that you can learn the language.
Does a similar site/app/plugin exist that will take me through a series of exercises to get familiar with CSS?
Thanks!
Currently there are no such comprehensive online tutorials on CSS.
However, I’d recommend http://dabblet.com/ for learning HTML&CSS — it have some features that makes it greater than jsfiddle:
BTW, it’s a great idea — to create the open tutorials based on any one tool available online, I hope that someone would do it (if noone would, well, maybe I’ll find some time for it).
