Hello All!
This should be pretty straight forward, but I'm having trouble adding a new class.
I've attached my CodePen example. Can anyone point me in the right direction to what I am doing wrong?
The example should change all the box colors from Blue to Green, then add the .blackBox class to the third box, then change all boxes without the .blackBox class to Red, leaving the third box Black.
Any input would be greatly helpful!
