Carbon is absolutely amazing. They are using a very flat style in pursuit of a modern corporate brand, just like a lot of other tech companies today, but the design also incorporates a lot of traditional and familiar elements. It’s a rare instance of flat UI that does not feel mobile oriented and half assed on desktop.

Carbon components are also the most accessible component set I have seen, and they go through great lengths doing automated and manual accessibility testing.

The library though, is a bit lackluster. It’s tailored for IBM’s internal need, and is still a bit far from a complete framework. So you need to be prepared to write some CSS as well as designing your own components when you need one.
