Which CSS frameworks work well with React?

I'm curious to know which CSS frameworks people are using with React. I've been told that Jquery doesn't mix well with React, and most of the popular frameworks out there are built on Jquery, so I'm not sure what I should go with. It also seems like most of the CSS frameworks built for React aren't really production ready.

So, should I be looking for a framework which was built for React, or can I get by with something like Bootstrap or Semantic-UI?

As an example, HashNode is a great looking React app. I'd love to which CSS framework was used, if any.
