Why do I have to use the property of "border-color" ?

I don't know the reason for putting border-color property here.

header { background: #6ab47b; border-color: #599a6b; }

because it works without it. This nav rule below changes the background color..

nav { background:#599a6b; }

So, I don't see the point to use border-color property here.

Sorry for my poor english and thanks for helping me in advance.

These two property change the color of two different things; the background changes the color of the background while the border-color changes the color of the border. However, if you don't have a border-width set, you won't see a change in the border color. So, something like this:

header { 
   background: #6ab47b; 
   border-color: #599a6b; 
   border-width: 2px;
}

Hey Masae!

Is this question directly related to a quiz question or are you working on an HTML document yourself? Can you give me more context? My first thought would be the nav background is more broad than the header border. You may select more than you bargain for when using the nav background. I'm not sure if that helps?

EDIT: Emma said it better! They are two different things. The same result may be occurring visibly, but it is probably coincidence. Be sure to specify a border-width.
