Default Do ribs move closer together during breathing?

Might seem like a simple question, but we can't find a single answer to this:
During inhalation, the external intercostal muscles contract and move the ribs.

Question is, do the ribs move closer to each other or not?

We found sources that say they do, we found sources saying they don't. Now we are confused.
