Hello @Johan-Jubin,
Great effort completing and submitting this challenge
Regarding your question about inheritance, it is my understanding that some properties inherit their parents computed value, and other properties do NOT inherit the parents computed value.
A typical example of an inherited property is the color
property.
A typical example of a non-inherited property is the border
property.
Take a look at the documentation here for more information.
I hope this helps
Well done on your submission
