When I add the test script to your pen, I see the following message for the failed user story.
- The navbar should always be at the top of the viewport. AssertionError: Navbar’s parent should be body and it should be at the top of the viewport : expected 15.994318008422852 to be close to 0 +/- 15
The element with id=“navbar” should be a direct child of the body element. Currently, it is nested in a nav element. You could move the id=“navbar” from the ul element to the nav element, rename your #navbar CSS selector to something like .nav-bar and then add this class to the ul element.
