Whenever I open Chrome developer tools, I come across something that puzzles me. I always assumed that a CSS property is crossed out when it's overwritten by another class.
However, I found myself in this peculiar situation:

This is at the top of the hierarchy, so I'm confused as to why it appears crossed out. If there was a syntax error, it should be accompanied by a warning sign. Can anyone clarify why it's displayed like this?
