CSS Blocks vs Glamorous: What are the differences?
Developers describe CSS Blocks as "A component-oriented CSS authoring system by LinkedIn". By combining an opinionated authoring system, build-time analysis and rewriting of templates, and a new type of CSS optimizer, css-blocks breathes new power and ease of use into the technologies and best practices that stylesheet developers already know and love. On the other hand, Glamorous is detailed as "Maintainable CSS with React". Glamorous is React component styling solved with an elegant (inspired) API, small footprint (<5kb gzipped), and great performance (via glamor). It has a very similar API to styled-components and uses similar tools under the hood (glamor).
CSS Blocks and Glamorous are both open source tools. It seems that CSS Blocks with 6.07K GitHub stars and 141 forks on GitHub has more adoption than Glamorous with 3.74K GitHub stars and 282 GitHub forks.
