A way of organising CSS (composition, utility, block, exception) that leans on the cascade instead of fighting it.

A CSS methodology by Andy Bell. CUBE stands for Composition, Utility, Block, Exception, and it is built to use the cascade and inheritance.
Composition handles macro layout and how elements fit together, utilities do one job each, blocks hold component-specific styles, and exceptions cover state changes. The site also has sections on grouping, examples and resources.
It takes inspiration from BEM but puts less weight on blocks. The site calls itself a work in progress and points to a blog post for a short introduction.
