ScalaCSS aims to bring type-safety and clarity to

creating CSS

using CSS

maintaining CSS

correctness of CSS

You can create standalone CSS like SCSS/LESS, or you can create inline styles to be applied to directly without the need to manually manage class names.

Being 100% Scala, you benefit from all the normal type-aware advantages like jump-to-definition of a style, type-safe keys and values, worry-free refactoring, etc.

The goals and vision of the project are documented in its requirements. Most requirements are satisfied; some will be addressed a little later.
