CSS as a Query Language

The author discusses how CSS can be used as a query language to do things other than layout web pages, and proposes a new language called CSSLog that combines CSS with Datalog to allow for recursive queries and transitive closure. CSSLog would allow for more complex queries and styles, but it's unlikely to be implemented in browsers due to its potential for infinite loops and fixpoint semantics.
