I think this article is not a great introduction to Stylus, it's a better idea to check out their Github page: <a href="http://learnboost.github.com/stylus/" rel="nofollow">http://learnboost.github.com/stylus/</a><p>While you can write functions to create abbreviated versions of CSS properties, it's entirely optional.<p>Also I actually prefer Stylus' mixins and functions to SASS'.
I kinda doesn't like the concept of such cryptic representations of standard language. May be by writing such way you saved a lot of characters, but anytime standard CSS is lot more readable thus maintainable.<p>Though I also feel, browser specific styles are really painful. And I also miss lack of functions, variable in CSS.
