Yes they are completely different , but they are the two that I have been bouncing back and forth in terms of where I should spend my energy. Because they are so different this is why i’m asking questions in terms on what is best.
I’m finding that just about anything you can do in less , sass, and scss you can pretty much do in stylus. Stylus accepts syntax for the coffescript type syntax as well as native css , and using or not using brackets. It even allows you to mix in directly in the same file.
