Good afternoon! :)
What does the discolored property mean in the browser inspector?

Answer 1

In the Browser Inspector (Chrome, new Opera, and others on webkit), grayed out indicates parent element settings that are not inherited by a child element.
In this case, letter-spacing inherits all of its children from the parent, but display does not.

Answer 2

Standard property from the browser?
