Toolkits are closer to a library than to a framework. They do not provide actual styling but utilities (e.g. mixins) that you can use in your CSS preprocessor.
Frameworks that have not seen any real development for more than about one year or officially have been deprecated. We are keeping them here for reference/inspiration and hope for a revival.
