Full Stack Path: One more problem

Sorry to say but there’s another fault in the course design.
This link takes you to the CSS code challenges where in the 4th exercise you will start getting that it’s wrongly placed.
It gets confirmed in the 7th exercise because all this border and positioning thing hasn’t been covered yet in the course and I think is covered after these code challenges.
I completely respect the amount of hard work it had to be done to design this course but wrongly placing the lessons and code challenges isn’t going to really help learners.
The link to previous problem is here.
I hope these get solved fast.
