Wait CSS supports nesting? Since when?

Also, SASS's mixins, variables (CSS has variables too but they work differently), and many of the other features are hard to beat, which is why I feel like it's almost never a negative to get it up and running on any project I work on (unless the project is a tiny one-off, then it's probably not worth it). One thing I like is that it's close to CSS - increasing the transparency - while still providing abstractions that let you save time and increase consistency across the project.
